Best Language: A great deal of information about comprehension will be 0= No aphasia; normal. For this scale item, the patient is asked to describe what is 1= Mild-to-moderate aphasia; some obvious loss of fluency or happening in the attached picture, to name facility of comprehension, without significant limitation on ideas items on the attached naming sheet and to read from the attached list of expressed or form of expression. Comprehension is judged from responses here, as well as to all of comprehension, however, makes conversation about provided the commands in the preceding general neurological exam. For example, in conversation interferes with the tests, ask the patient to identify objects placed in the hand, about provided materials,examiner can identify picture or repeat, and produce speech. The examiner must choose a score for the patient with stupor or limited cooperation, 2= Severe aphasia; all communication is through fragmentary but a score of 3 should be used only if the patient is mute and follows no oneexpression; great need for inference, questioning, and guessing step commands. Range of information that can be exchanged is limited; listener carries burden of communication. Dysarthria: If patient is thought to be normal, an adequate sample of speech 0= Normal. If the 1= Mild-to-moderate dysarthria; patient slurs at least some patient has severe aphasia, the clarity of articulation of spontaneous speech can words and, at worst, can be understood with some difficulty. Sufficient information to identify neglect may be obtained during the prior testing.

If the inattention or extinction to bilateral simultaneous patient has aphasia but does appear to attend to both sides, stimulation in one of the sensory modalities. The presence of visual spatial neglect or anosagnosia may also be taken as evidence of abnormality. Since the abnormality is scored only if 2= Profound hemi-inattention or extinction to more than one present, the item is never untestable. Section 1: Orientation the first 10 points are gained for giving the correct date and location. Section 2: Memory (part 1) the first part of the memory test tests the ability to remember immediately three words. You will be given the names of three objects to remember – table, ball and pen, for example. You will then be asked to repeat the three names, scoring 1 point for each object correctly recalled (3 points maximum). If you can’t remember all three objects, the person testing you will repeat the words. You should try to remember the three items as you will be asked to recall them later in the test. Two different tests are used, and the best of the two scores is included in the final score. Section 4: Memory (part 2) You will now be asked to recall the three items from Section 2. The attention and calculation section may have been quite a stressful experience, so this can be tricky. Section 5: Language, writing and drawing the final part of the test makes an assessment of spoken and written language, and the ability to write and copy. The person being tested is shown two everyday items – a hammer and a crayon, for example – and asked to name them. You will then be asked to say aloud a tongue-twister sentence such as ‘Pass the peas please’. The sentence is always the same, so is worth practicing once you have heard it the first time. You will then be given a piece of paper, and asked to carry out a three-step process: ‘Take this paper in your hand’ (1 point); ‘Fold it in half’ (1 point); ‘Place it on this chair’ (1 point). The instruction is given only once, but as with the tongue-twister, the task is always the same. One point is scored for an acceptable sentence, and this is again something that can be practised in advance. All angles on both figures must be present, and the figures must have one overlapping angle. You should ask for your score and ideally have it written down for you to take away. If you feel that you haven’t done the test very well, perhaps because of nervousness, or simply because you were having a bad day, you could ask for the test to be repeated on another day.

As a result, the rest of the body cannot receive enough blood that is rich in oxygen and nutrients. These conditions share many of the same risk factors, including diabetes and high blood pressure. An exercise stress test can also test for heart disease and looks for risk of future damage. Other blood tests and imaging studies are needed to determine the cause of kidney disease. Opening those blockages with stents or bypass surgery can improve heart function in some cases. Anticoagulants and antiplatelets are medicines that can be used to help prevent harmful blood clots. Medicines, such as statins, can be used to control cholesterol along with a diet low in saturated fat, in addition to exercise. It can be treated with a low sugar diet and medicines (such as insulin, and/or other oral medications). These conditions are managed with more physical activity, a modified diet, and medications. When kidney disease progresses, it may eventually lead to kidney failure, which requires dialysis or a kidney transplant to maintain life. Obesity contributes to high blood pressure and diabetes, which can hurt the kidneys and heart.

Conclusion: this national audit demonstrated similar outcomes overall compared to relevant published data. Body: Background: Autologous fat grafting has become a frequent, simply reproducible and low-risk technique in breast reconstruction. The potential risk of fat tissue transfer to the breast for oncologic patients remains to be discussed, but one must clearly distinguish the situation where there is a breast parenchyma left and where the whole gland has been removed, like in our study. Although lipotransfer has become very popular, only a limited number of case series have been reported up to date. The presented study evaluates aesthetic results and quality of life after exclusive fat grafting breast reconstruction. Patients and methods: A retrospective study was performed in two French centers with five surgeons between February 2011 and June 2015. We included patients with prior breast cancer, treated by mastectomy and with a finished breast reconstruction with exclusive fat grafting. For each patient, the aesthetic evaluation was threefold, performed by the patient, the surgeon and an extra person, using the same questionnaire. For the analysis of the cosmetic results, the patients, surgeons and the other person were asked to grade the result on a 0 to 10 scale, ranging from "very bad" to "very good". They were questioned about the global esthetic result, symmetry between the two breasts and reconstructed breast texture. Satisfaction was evaluated using a Breast-Q adapted questionnaire, elaborated by psycho-oncologists and surgeons. The mean age of the patients was 52 years, 31 patients (81,6%) lived in couple and 29 patients (76,3%) were employed. The mean total quantity of fat injected was 904 ml per patient with a mean quantity per procedure of 219 ml. The average grade obtained for the global esthetic result was 7,3 +/1,8 out of 10 for patients, 7,6 +/-2 for the extra person and 7,9 +/1,4 for surgeons. For symmetry between the two breasts, the result was 7,1 +/1,9 and for the texture, it was 6,8 +/2,6. Among the 29 patients having a professional activity, 86% (25/29) of patients were able to work between each fat grafting session. The handicap evaluation in the professional life for these patients from 0 "no handicap "to 10 " important handicap showed a score of 2,24 +/-2,7. As for global quality of life evaluation, to the question: "how would you grade your quality of life? Conclusion: Autologous fat grafting can be offered as a good alternative for total reconstruction after mastectomy with good aesthetic results and no deleterious impact on quality of life.

However its use remains limited, especially for women over 65 years, with a large degree of international variation. Controlling for possible confounders, older patients have less breast reconstruction. This apparent heterogeneity can be part of women choice, however it suggests unequal access to high quality procedures for older women with breast cancer. The duration of the surgery, the rate of postoperative complications, the length of the scar, the duration of drainage and hospital stay, the rate and duration of rehospitalization were also analyzed. Patients were discharged home between the 4th and the 10th postoperative day after the removal of the drain. Conclusion: Preliminary data attest to the feasibility, the reproducibility and the safety of this approach. Body: Background: Women who undergo mastectomy for breast cancer treatment often undergo implant based or autologous reconstruction. There are limited data, however, as to whether reconstruction may interfere with detection of a locoregional recurrence. The goal of this study was to assess whether women who undergo reconstruction after mastectomy have an increased risk of local recurrence and/or longer time to local recurrence detection. Methods: One hundred and fifty-four premenopausal patients who underwent neoadjuvant chemotherapy followed by mastectomy were identified between 2005 and 2015. Patient and treatment variables were collected, including clinical stage, type of chemotherapy, type of surgery and reconstruction, use of postmastectomy radiotherapy, and use of endocrine therapy. Of the 154 patients, 71 (46%) underwent unilateral mastectomy and 83 (54%) underwent bilateral mastectomies. Thirty patients (19%) elected to forgo reconstruction while 78 (51%) received tissue expander/implant based reconstruction, 29 (19%) received autologous reconstruction, and 17 (11%) had unknown reconstruction histories. Conclusions: Premenopausal patients treated with neoadjuvant chemotherapy followed by mastectomy with any type of reconstructive surgery had an increased time to local recurrence detection compared to those without reconstruction. Body: Purpose Breast conservation has become the mainstay of surgical management for early stage breast cancer. Oncoplastic surgery publications have recently increased by 220%, demonstrating the increasing popularity of this surgical technique, 2 and many of these studies have demonstrated excellent oncologic outcomes. The search included keywords such as oncoplastic breast surgery, lumpectomy, partial mastectomy, and positive margins associated with breast surgery. The inclusion criteria for our study included histology discrepancy, and new guideline margin status. Of the 45 papers evaluated, 34 were not included due to exclusion criteria (missing: new margin guidelines, histology, or margin status). Body: Background: Breast cancer is the most common cancer among European women with 54,000 new cases in France in 2015. Mastectomy is still needed in 30% of cases, resulting in significant physical and psychological consequences. The objective of the study was to find the factors influencing the decision-making process for attempting breast reconstruction in women who are over 65. Methods: We included retrospectively all patients over 65 years old who had an immediate or delayed breast reconstruction in our Cancer Center from January 2006 to July 2016. Forty-one percent of patients sought out sources of information other than their surgeon (other physicians, friends, other patients, the internet – no significant differences between the two groups, p=0. None of the women reported that her surgeon considered her age to be an obstacle for breast reconstruction. Patients had less opportunity to talk about their fears with their surgeon in the mastectomy group (19. This dedicated information should help women over 65 to conclude that their age should not be a limiting factor for the decision to attempt breast reconstruction. Every patient was systematically sent for an evaluation of aesthetic result, pain and satisfaction on the second, the sixth and the twelth month. The global mean operative time was 360,1 minutes, including bilateral and robotically-assisted mastectomies. The other cases resulted in successful reconstructions without heavy complications.

Body: Introduction Breast reconstruction is an important option for patients who undergo mastectomy for breast cancer. Several studies have investigated outcomes for patients who undergo either immediate or delayed reconstruction versus mastectomy alone but few have evaluated the relationship of the timing of reconstruction to oncological outcome. Aim To determine if there is a difference in oncological outcomes for patients who undergo delayed versus immediate breast reconstruction following mastectomy for breast cancer. Methods Patients who underwent immediate or delayed breast reconstruction between 2005 and 2006 were identified from a database maintained prospectively at the regional plastic surgery unit. Tumour pathology details were obtained retrospectively from the electronic patient record and from local electronic laboratory systems. In the delayed reconstruction cohort, patients who underwent reconstruction 6-60 months after initial cancer surgery were included. In the immediate reconstruction group, patients who had recurrence or died within the first 6 months after surgery were excluded. Logistic regression survival analysis was carried out for the two cohorts and compared using Chi square test. Results 193 patients who underwent immediate reconstruction and 116 patients who underwent delayed reconstruction were identified. Of those who had delayed reconstruction, median time from initial cancer surgery to reconstructive surgery was 27 months (6-58 months). There were 49 breast cancer deaths, 13 deaths from other causes and 65 recurrences. Median follow up time from reconstruction, of those who survived, was 111 months (29-134 months). Conclusion Our data has demonstrated no difference in cancer specific survival or recurrence rates in patients who underwent mastectomy with immediate breast reconstruction compared to patients who had delayed reconstruction. Body: Background:Immediate breast reconstruction following mastectomy is a key quality metric of a comprehensive breast cancer program. Fat grafting has been found to be a safe and effective adjunct to standard breast reconstructive techniques. Fat graft only breast reconstruction has been reported, but in conjunction with external suction based tissue expansion. Dermatocutaneous flaps have been described for immediate breast reconstruction, but only in large breasted women (Goldilocks technique). We used micro fat grafts alone (no pre expansion) and in combination with dermatocutaneous flaps at mastectomy, to reconstruct small to medium sized breasts. We have applied the fat graft only technique to both immediate and delayed reconstructions. Purpose: To present a novel, minimally invasive approach to reconstruction of small and medium sized breasts utilizing immediate or delayed micro fat grafts with and without immediate dermatocutaneous flaps. We also present immediate single stage bilateral breast reconstruction utilizing fat grafts, dermatocutaneous flaps, and nipple reconstruction. The authors will review patient selection criteria, surgical technique and present before and after photos. Results: 12 non radiated breast cancer patients underwent immediate reconstruction of 21 breasts, utilizing fat grafting (1 breast) or dermatocutaneous flaps and fat grafting (20 breasts). An additional 5 patients underwent a total of 8 delayed fat graft only breast reconstructions. One patient underwent immediate reconstruction of one breast and delayed reconstruction of the other. For immediate fat graft reconstructions, volume of fat grafted at the time of the mastectomy averaged 76 ml (range 55-100 ml). Conclusion: the authors present a simple, minimally invasive approach to immediate and delayed breast reconstruction of small to medium sized breasts. Our approach is novel in that it combines fat grafts with dermatocutaneous flaps for immediate reconstruction and utilizes serial fat grafts without pre expansion for complete delayed breast reconstruction. The technique has been successfully utilized to complete both immediate unilateral and bilateral breast reconstruction in a single stage in select patients and with serial fat grafts in others. Body: Background: To avoid tissue expander exposure following mastectomy flap necrosis, several methods for covering expander by autologous flap in cases of immediate breast reconstruction have been reported. These methods are classified into two groups, complete or partial expander coverage. Two methods have potential risks of postoperative complications following: insufficient lower pole expansion and cranial migration in complete coverage methods, and lateral migration in partial coverage methods. However, the comparisons of complication rates between these two methods have not been reported. This study aims to compare the incidence of expander exposure following mastectomy flap necrosis and expander migration between two methods. Methods: A retrospective review of 93 patients (99 breasts) who underwent immediate expander-based breast reconstruction was performed. Patients were divided into two groups, complete or partial expander coverage by autologous flaps. In partial coverage group, the lateral borders of pectralis major muscles were sutured to the mastectomy skin flaps. If the skin flap was too thin to be sutured, the serratus anterior muscro-fascial flap was dissected and sutured to the lateral border of pectralis major muscle to cover the expander completely. Demographics, intraoperative findings, and postoperative complications were compared between two groups.

One-way or multi-way In economic evaluations medications to avoid during pregnancy discount lithium 300 mg otc, one-way simple sensitivity analysis sensitivity analyses varies each parameter individually in order to isolate the consequences of each parameter on the results of the study medicine to reduce swelling order lithium with paypal. Multi-way simple sensitivity analysis varies two or more parameters at the same time and the overall effect on the results is evaluated medicine jar generic 150mg lithium with mastercard. Opportunity costs the cost of foregone outcomes that could have been achieved through alternative investments medications causing gout discount lithium 150mg visa. Outcome An aspect of a participant’s clinical or functional status that we seek to change through intervention treatment wax buy lithium 150 mg otc, for example survival treatment plans for substance abuse order lithium paypal, tumour recurrence, conception, live birth, level of anxiety, frequency of asthma attacks. Partial veriﬁcation bias A type of bias that occurs when only a selected sample of participants undergoing the index test also receive the reference standard. Per protocol analysis An analysis restricted to those participants in a study who followed the trial protocol closely enough to ensure that their data would be likely to show an effect of treatment if it existed. Per protocol analysis may be subject to bias because the reasons for not following the protocol may be related to treatment. Performance bias Bias resulting from systematic differences in care provided to those in each intervention group (other than the intervention being evaluated) that arise because carers or participants act differently because they know which intervention is being delivered. Peto odds ratio Calculates odds based on the difference between the observed number of events and the number of events that would be expected if there was no difference between experimental and control interventions. It can also be used to combine time to event data by pooling log rank observed–expected (O – E) events and associated variance. It can give biased estimates when treatment effects are very large, or where there is a lack of balance in treatment allocation within the individual studies. Piloting the process of testing a procedure on a small scale before introducing it into practice. Placebo An intervention without speciﬁc biological activity in the condition being treated, usually administered to compare its effects with those of an active intervention. Placebos are used because the act of intervention (rather than the intervention itself) may bring about some beneﬁt for psychological or other reasons. Positive predictive value the probability of disease among persons with a positive test result. Precision A measure of the likelihood of random errors in the results of a study, meta-analysis or measurement. The term is sometimes used to distinguish such studies from secondary studies that re-examine previously collected data. Probabilistic sensitivity analyses In economic evaluations, probabilistic sensitivity analysis attributes distributions of probabilities to the uncertain variables which are incorporated into evaluation models based on decision analytical techniques. Prognostic markers (biomarkers) Characteristics that help to identify or categorise people with different risks of speciﬁc future outcomes. Prognostic tests Tests conducted to assess a patient’s risk of a particular outcome. Prospective study A study in which participants are identiﬁed and then followed forward in time to observe whether particular outcomes do or do not occur. Publication bias Bias arising from the fact that studies with statistically signiﬁcant results are more likely to be published than those with inconclusive results. As a result, systematic reviews that fail to include unpublished studies may omit relevant research and are likely to be biased towards the positive and overestimate the effect of an intervention. A very small p-value means that it is very unlikely that the observed effect has arisen purely by chance and provides evidence against the null hypothesis. Sometimes used as an indicator of overall test performance where there is no clinical preference for maximising either sensitivity or speciﬁcity. Qualitative comparative analysis A method for summarising and comparing data from case studies using Boolean logic. Qualitative meta-summary A set of techniques for aggregating qualitative research ﬁndings. Qualitative meta-synthesis A set of techniques for the interpretive integration of qualitative ﬁndings. Qualitative research Research that adopts an interpretive, naturalistic approach and studies things in their natural settings. Quality threshold In systematic reviews, restricting inclusion to studies that meet predeﬁned criteria related to quality (validity). Quantitative research Research that concentrates on describing and analysing phenomena by using numerical data and empirical models. Quantitative synthesis See Meta-analysis Randomisation the process of allocating participants to one of the groups of a randomised controlled trial using (i) a means of generating a random sequence and (ii) a means of concealing the sequence, such that those entering participants to a trial are unaware of which intervention a participant will receive. This should ensure that intervention groups are balanced for both known and unknown factors. Reference standard the best currently available diagnostic test, against which the index test is compared. Regression analysis A statistical modelling technique used to estimate or predict the inﬂuence of one or more independent variables on a dependent variable. Regression to the mean A statistical phenomenon by which extreme examples from any set of data are likely to be followed by examples which are less extreme; a tendency towards the average of any sample. For example, the offspring of two very tall individuals tend to be tall, but closer to the average (mean) than either of their parents. Relationship marketing Developing long-term relationships with customers in order to retain them; relationship marketing techniques focus on customer retention and satisfaction. Reporting bias A bias caused by only a subset of all relevant data being available for inclusion. For example through not all trials being published or not all outcomes being reported. Research synthesis the combination and evaluation of separate studies to provide a coherent overall understanding to a research question. Retrospective study A study in which the outcomes have occurred to the participants before the study commenced. For example, if out of 100 participants 20 have a myocardial infarction, the risk of infarction is 0. For example, if the control group has a 30% risk of experiencing a particular event and the intervention group has a 20% risk of experiencing the event, the risk different is 10%. Risk factor An aspect of an individual’s genetic, physiological, environmental, or socioeconomic state that affects the probability of them experiencing a particular disease or outcome. For example people with high body mass index are at increased risk of developing diabetes. Sample size calculation A calculation performed when planning a clinical study to determine the number of participants needed to ensure a given probability of detecting an effect of a given magnitude if it exists. Some consist merely of a text box in which a limited number of words can be entered. For example, many search interfaces allow searches for terms occurring within so many words of each other (known as adjacency searching). Search strategy the exact terms and their combinations used to search a bibliographic database. Bias caused by systematic differences between comparison groups in prognosis or responsiveness to treatment. Bias caused by systematic differences between those who are selected for a study and those who are not. This affects the generalisability (external validity) of a study but not its (internal) validity or risk of bias. Bias arising from the way in which studies were selected for inclusion in a systematic review, for example, publication bias. Sensitivity In diagnostic/screening tests, a measure of a test’s ability to correctly identify people with the disease or condition of interest. In literature searching, the proportion of relevant articles that are retrieved using a speciﬁc search strategy. Sensitivity analysis An analysis used to test the robustness of ﬁndings and determine how sensitive results are to the data that were included and/or the way that analyses were done. Sham (surgery/device) An activity that makes the recipient believe they have received the actual intervention when they have not;. Speciﬁcity In diagnostic/screening tests, a measure of a test’s ability to correctly identify people who do not have the disease or condition of interest. In literature searching, the proportion of non relevant articles that are not retrieved. Stakeholder In systematic reviews a person or group with an interest in or potentially affected by the results of the review. Standardised mean difference the difference between two estimated means divided by an estimate of the within-group standard deviation. It is used to standardise and combine results from studies that have used different ways of measuring the same concept. Statistical power the probability of rejecting the null hypothesis when a speciﬁc alternative hypothesis is true. In comparative studies the chance of detecting a real effect as statistically signiﬁcant, given that the effect actually exists. Studies with a given number of participants have more power to detect large effects than to detect small effect. Sub-group analysis In a clinical study or systematic review, an analysis in which the effect of the intervention is evaluated in a deﬁned subset or subsets of participants. Summary data Data that have been aggregated for presentation or analysis, for example numbers of events in each group in a clinical trial. These are often physiological or biochemical markers that can be obtained much more quickly compared to the clinical outcome of interest. To be valid, a surrogate outcome must have been shown to correlate with and accurately predict the outcome of interest. Test accuracy study A one-sided comparison between the results of an index test and those of a reference standard. Thematic analysis/synthesis A method used in the analysis of qualitative data to systematically identify the main, recurrent and/or most important themes and/or concepts across multiple responses. Threshold analyses In economic evaluations, threshold analysis identiﬁes the critical values of the parameters above or below which the results of a study vary. Time horizon the time span that reﬂects the period over which the main differences between interventions in health effects and use of health care resources are expected to be experienced. Time preferences the predilection of an individual (or a society) for the use of resources in the present rather than in the future. Time-to-event data Data that reﬂect not just whether an event occurs but the time at which it happens. Each data item is represented by a state variable indicating whether or not an event has occurred and an elapsed time at which the state was assessed. Individuals who have not (yet) experienced the event at a particular point in time are censored and contribute their event-free time to the analysis. Triangulation A research strategy in which the researcher observes the same variable or phenomenon with multiple sources, measures, and methods. Truncation symbol A symbol used when searching electronic databases to retrieve all words that begin with a particular stem. Update searching the re-running of a literature search to capture material that has become available since the original search was conducted. May involve re-writing search strategies to take account of changes in terminology and database indexing. Validity (of a measurement) the degree to which a measurement truly measures what it purports to measure. Weighting In meta-analysis, the relative contribution of each individual study to the overall result and/or the method used to determine this. Studies are often weighted by the inverse of the variance of their measure of effect so that studies with more statistical information make a relatively greater contribution. Worst/best case analysis In economic evaluations, a sensitivity analysis using extreme values for the input data to investigate the outcome of the economic evaluation in the extreme case. Graf, PharmD, of the National Pharmaceutical Council, who reviewed and contributed to the document. As the number of treatment options for many conditions has increased, decision-makers have begun seeking comparative information to support informed treatment choices. Comparative efectiveness information is often not available, however, either due to lack of funding, or because clinical research focuses on demonstrating efcacy. Efcacy measures how well interventions or services work under ideal circumstances, while efectiveness examines how well interventions or services work in real-world settings, where patients may have more complex conditions. The Institute of Medicine has estimated that less than half of all medical care in the United States is supported by adequate efectiveness evidence. For example, tradeofs of validity, relevance, feasibility, and timeliness must be considered in the context of the specifc decision-makers and decisions. In experimental designs, patients are randomized (assigned by chance, not by a physician’s decision) to a particular therapy based on the study protocol. In nonexperimental designs, patients and physicians make real-world treatment decisions, and patterns of care and outcomes are observed. Others believe that nonexperimental studies, incorporating ways to address channeling bias and other confounding in the design and/or analysis, represent important alternatives to randomized studies. Each design or analytic topic is described, along with the strengths and limitations associated with the approach. Examples are provided to demonstrate the use of the described methods in the literature. This document is organized into four sections: experimental study designs; experimental methods; nonexperimental study designs; and nonexperimental methods. Rather, trials may incorporate difering degrees of pragmatic and explanatory components. For example, a trial may have strict eligibility criteria, including only high-risk, compliant, and responsive patients (explanatory side of the spectrum), but have minimal to no monitoring of practitioner adherence to the study protocol and no formal followup visits (pragmatic side of the spectrum).

A pair of coaxial catheters (typically a 5-F mammary diagnostic catheter inside a 6-F extra backup shapeguiding catheter) was positioned in the targeted aortic leaﬂet scallop to direct a guidewire across it, near the scallop hinge point, by echocardiographic and angiographic guidance. These aimed at a snare positioned immediately below the leaﬂet using a separate retrograde catheter (Figure 2, Online Video 1). After externalization of the free guidewire end, the guidewire straddles across the leaﬂet scallop between 2 catheters.

These included mitral chord entrapment and laceration resulting in severe mitral regurgitation; misdirected wire traversal into the left atrium or interventricular septum, the latter causing ventricular ﬁbrillation requiring deﬁbrillation; and partial annular laceration without pericardial effusion from annulus rather than leaﬂet traversal. There was no macroscopic evidence of collateral thermal damage in benchtop or in vivo necropsy specimens. There were a range of diseased aortic valve substrates: 1 had a porcine aortic stent-less bioprosthetic valve, 1 had a stent-less bovine pericardial valve, 4 had stented bovine pericardial valves, and 1 had native aortic valve stenosis. One of the 7 required laceration of 2 aortic leaﬂet scallops and the rest of only the left. All were believed to be unsuitable for surgery by the multidisciplinary heart teams. Five had prior coronary artery bypass grafts that were believed not to protect threatened vessels. All were believed to be at high risk of left coronary obstruction with median coronary height of 6. The laceration was central and along most of the leaﬂet length as depicted on transesophageal echocardiography (Figure 8B). Heart rate and systolic blood pressures were unchanged in all cases, and no patient required pharmacologic or mechanical hemodynamic support in the 8 to 30 min between laceration and valve deployment, nor afterward.

The diagnosis of heart failure is often determined by a careful history and physical examination and characteristic chestradiograph findings. The measurement of serum brain natriuretic peptide and echocardiography have substantially improved the accuracy of diagnosis. The cornerstone of treatment is a combination of an angiotensin-converting-enzyme inhibitor and slow titration of a blocker. Key words: heart failure, diastolic dysfunction, systolic dysfunction, obstructive sleep apnea, Cheyne-Stokes respiration, respiratory failure, noninvasive ventilation. The magnitude of the annual New Horizons symposium at the 51st International Respiratory Congress of the American Association for Respiratory Care, held Deproblem cannot be precisely assessed, because reliable popcember 3–6, 2005, in San Antonio, Texas. The most common causes of systolic dysfunction (defined by a left-ventricular ejection fraction of 50%) are ischemic heart disease, idiopathic dilated cardiomyopathy, hypertension, and valvular heart disease. Diastolic dysfunction (defined as dysfunction of left-ventricular filling with preserved systolic function) may occur in up to 40–50% of patients with heart failure, it is more prevalent in women, and it increases in frequency with each decade Fig. Diastolic dysfunction can occur in many of the same conditions that lead to systolic dysfunction. The most standing the pathophysiologic consequences of heart failcommon causes are hypertension, ischemic heart disease, ure and the potential treatments. Furthermore, an apprecihypertrophic cardiomyopathy, and restrictive cardiomyopation of cardiopulmonary interactions is important in our athy. In the simplest terms, the heart failure (shortness of breath, peripheral edema, parheart can be viewed as a dynamic pump. It is not only oxysmal nocturnal dyspnea) but also have preserved leftdependent on its inherent properties, but also on what is ventricular function may not have diastolic dysfunction; pumped in and what it must pump against. The preload instead, their symptoms are caused by other etiologies, characterizes the volume that the pump is given to send such as lung disease, obesity, or occult coronary ischforward, the contractility characterizes the pump, and the emia. In developed countries, ventricular dysfunction nous pressure minus pleural pressure) and thus reduce venaccounts for the majority of cases and results mainly from tricular filling. The cardiac pump is a muscle and will myocardial infarction (systolic dysfunction), hypertension respond to the volume it is given with a determined output. If volume increases, so will the amount pumped out in a Degenerative valve disease, idiopathic cardiomyopathy, normal physiologic state, to a determined plateau; this and alcoholic cardiomyopathy are also major causes of relationship is described by the Frank-Starling law (Figs. Diastolic function is determined by mon comorbidities such as renal dysfunction are multifac2 factors: the elasticity or distensibility of the left ventritorial (decreased perfusion or volume depletion from cle, which is a passive phenomenon, and the process of overdiuresis), whereas others (eg, anemia, depression, dismyocardial relaxation, which is an active process that reorders of breathing, and cachexia) are poorly understood. Loss of normal leftdeterminants of cardiac output include heart rate and stroke ventricular distensibility or relaxation by either structural volume (Fig. The stroke volume is further determined changes (eg, left-ventricular hypertrophy) or functional by the preload (the volume that enters the left ventricle), changes (eg, ischemia) impairs ventricular filling (preload). A previous myocardial infarction may result in nonfunctioning myocardium that will impair contractility. A recent concept is that ischemic myocardial tissue can be nonfunctioning (hibernating) but revitalized by surgical or medical therapy directed at ischemic heart disease. In basic terms, afterload is the load that the pump has to work against, which is usually clinically estimated by the mean arterial pressure. The Frank-Starling law of the heart states that as the venalso the wall tension and intrathoracic pressure that the tricular volume increases and stretches the myocardial muscle myocardium must work against. Together, these 3 varifibers, the stroke volume increases, up to its maximum capacity. If stroke volume cannot be maintained, then heart rate must increase to maintain cardiac which elevates left-atrial pressure and pulmonary venous output. Initially, this response will suffice, but proBased on autonomic input, the heart will respond to the longed activation results in loss of myocytes and maladapsame preload with different stroke volumes, depending on tive changes in the surviving myocytes and the extracelinherent characteristics of the heart. The stressed myocardium undergoes remodeling and dilation in response to the insult. Remodeling also results in additional cardiac decompensation from complications, including mitral regurgitation from valvular annulus stretching, and cardiac arrhythmias from atrial remodeling. Patients’ presentation can greatly differ, depending on the chronicity of the disease. For instance, most patients experience dyspnea when pulmonary-artery occlusion pressure exceeds 25 mm Hg. This series of Frank-Starling curves demonstrates that at any given preload (end-diastolic volume), increases in contractility capillaries are recruited and increase capacitance to deal with the added volume. At this point, by action of pressure gradients, fluid will form in the interlobular septae and the perihilar region.
