This book was released on 2012-12-06 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers presented at the Fifth International Symposium on Heart Valves and published in this volume discuss clinical experience with heart valve replacement in pediatric patients, in adults (age 65 and younger), and in the elderly (age 66 and older). Special considerations in heart valve replacement, such as valve selection, reoperation, results of double valve implantation, quality of life, and the use of valved conduits are also included. Finally, long term clinical follow-up with the ST. JUDE MEDICAL® heart valve, giving 7- and 8-year data is discussed. HEART VALVE REPLACEMENT IN PEDIATRIC PATIENTS Anticoagulation Anticoagulation in children is a difficult and interesting problem. Three princi pal considerations in the use of anticoagulants are patient education, timing, and anticoagulating substance. Additional considerations are patient tolerance and compliance. Generally, the findings indicate, if pediatric patients receive anticoagulation following mechanical valve replacement, it is well accepted and results in few complications. If children are not anticoagulated, complications arise. Conflicting results regarding the efficacy of PERSANTINE® and the use of aspirin vs. COUMADIN® were reported. Doctor Sade's data address some of these questions. * After a 5-year study in * See J Thorac Cardiovasc Surgery 1988; 95:533-561.

Download or read book Guide to Prosthetic Cardiac Valves written by Dryden Morse and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weare entering an especially prolific era in reporting and publishing clinical experiences with cardiac valve replacement. A voluminous litera ture on this subject is already in existence, emanating from clinicians, surgeons, bioengineers, and other scientists. Additionally, information presented at heart valve symposia in the form of bound collections reaches the shelves of the medical book stores every year. This activity reflects the dynamic state of cardiac valve technology, highlighted by the introduction each year of new valve designs that often utilize new materials. As a result, the authors recognized the need to update their book The Pacemaker and Valve Identification Guide, separating the contents into two volumes dealing with pacemakers* and cardiac valve technology. For this Guide to Prosthetic Cardiac Valves, we have gathered a group of recognized authorities in the field, all of whom have contributed in depth analysis in their areas of expertise. New material dealing with the preoperative and postoperative care ofthe heart valve patient, pathol ogy of cardiac valves, bioengineering problems of cardiac valve technol ogy, and separate chapters on valve implantation in children and ultra sonography have been added. Chapter 3, "The Radiology of Prosthetic Heart Valves," we feel will be particularly helpful to the physician in identifying a prosthetic valve and revealing the most likely complica tions. Chapter 10 is an atlas with descriptions to supply the reader with the essential features of the various prostheses when he or she is faced with a new patient bearing an implanted cardiac valve.

Download or read book Heart Valve Surgery written by Jan Dominik and published by Springer Science & Business Media. This book was released on 2010-05-26 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: T e four heart valves reside in the center of the heart. T is indicates their crucial role in cardiac performance. Fau- less function of the valves is a prerequisite for unidir- tional forward movement of the blood, and such function is necessary to support the ef orts of the cardiac atria and ventricles. Healthy heart valves function gracefully and of er mechanical durability. Bioengineers have to marvel at the biomechanical evolution of these perfectly placed valves. Heart valves can be involved in pathological processes, however, and only then do we realize just how indispensable they really are. At one time, serious valve disorders used to be a matter of life and death for patients. Only in recent decades have surgeons been able to reverse the ominous course of heart valve disease and of er patients a quality of life and life span comparable to that of healthy persons. T e story of this ef ort began approximately 100 years ago, and today heart valve surgery is a substantial subspecialty of cardiac surgery, with accumulated experience in indications, procedures, risks, and outcomes. T e aim of this book is to present a richly illustrated compendium of the present knowledge related to heart valve surgery, based on the clinical expertise of the authors as well as the newest treatment modalities. T e authors thank Dr. Alireeza Matloobi from the Mayo Clinic for his help in preparating the book.

Book excerpt: Each year, over 250,000 heart valve repair and heart valve replacement operations are performed for conditions including stenosis, prolapse, insufficiency, aneurysm, Tetralogy of Fallot and regurgitation. However, most patients and caregivers surveyed felt their expectations were mismanaged - both before and after surgery. The Patient's Guide to Heart Valve Surgery was written by Adam Pick, a double heart valve surgery patient, to address this troubling issue and prepare the patient and caregiver for the challenges and opportunities of valve surgery - from diagnosis through recovery.

Download or read book Pathology of Heart Valve Replacement written by A.G. Rose and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dr Rose honoured me with a request for a Foreword. I am delighted to oblige. The treatment of valvular heart disease has improved remarkably in the past 40 years. Many factors have contributed; not least being the introduction of artificial heart valves for treatment, more than 25 years ago. Their use has shown that they are good, but not an ideal substitute for native valves. A galaxy of pathological changes are associated with the insertion and malfunction of artificial heart valves. Each has to be defined, classified and related to clinical procedures or problems with a prosthesis; then a means sought to prevent them. Often, in understanding their cause, investigative procedures have/will improve patient care and broaden knowledge in other spheres. Dr Rose has been a student of this pathology for many years and has made many contributions. No doubt his interest in the area was whetted by colleagues in Cape Town, leaders in the field of cardiovascular medicine and surgery. This monograph provides a collected review of his experience. In it one finds lessons in geographic pathology, in considering the causes of valvular heart disease in Cape Town and valuable information regarding the identification of artificial heart valves and a means of examining a heart bearing one.

Download or read book Cardiac Valve Replacement written by Jack M. Matloff and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiac Valve Replacement: Current Status is the proceedings of the Fourth Interna tional Symposium on the ST. JUDE MEDICAL@ valve. The first three symposia on this topic were held primarily for designated investigators involved in clinical trials of the ST. JUDE MEDICAL valve. The last meeting, chaired by Michael E. DeBakey, M.D., was held in November 1982 [1], immediately before the valve was released for general clinical use in the United States by the Food and Drug Administration. These proceedings then are the first comprehensive compilation of clinical data since that time; and they include, particularly in the discussions, the experience of physicians other than the original clinical investigators. Over the past 5 years the character of these symposia has changed. Whereas the first two dealt almost entirely with the ST. JUDE MEDICAL valve, the last two have evolved into a more generic cardiac valvular surgery meeting, focusing primarily on valve replacement rather than valve repair [2]. Thus, these proceed ings contain a wide spectrum of topics, including a keynote presentation on criteria for selection of cardiac valve substitutes in 1984, complications of cardiac valve replacement and their treatment, a review of the current status of cardiac valve substitutes other than the ST. JUDE MEDICAL valve and a consideration of cardiac valve replacement in special circumstances. Among these special circum stances are four presentations on pediatric use of the ST. JUDE MEDICAL valve.

Download or read book Learning Cardiac Auscultation written by Allen J. Taylor and published by Springer. This book was released on 2015-10-13 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book contains a series of core auscultation “lessons”. All are case based and describe auscultation as it relates to a patient and in terms of the gold standard for interpretation of heart sounds. Auscultation is the term for listening to the internal sounds of the body, usually using a stethoscope. It is performed for the purposes of examining the circulatory system and respiratory system (heart sounds and breath sounds). As a topic it is one of the oldest in cardiology but its utility should never be underestimated. In this era of hugely expensive imaging tests, auscultation is a cornerstone of efficient diagnosis and therefore needs a fresh look. The core content of this book describes the search for diagnostic clues within patients’ heart sounds and as such this book provides superb practical advice in the form of a series of clinical pearls reflecting what accurate diagnosis with auscultation can mean to patient prognosis and outcome. This often subtle but ultimately simple subject often produces complex results and these must be considered in light of modern next-level diagnostic methods and patient management.

Download or read book Percutaneous Heart Valve Replacement written by U. S. Department of Health and Human Services and published by Createspace Independent Pub. This book was released on 2013-05-06 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the proportion of older adults increases in the U.S. population, the prevalence of degenerative heart valve disease is also increasing. Calcific aortic stenosis (narrowing) and ischemic and degenerative mitral regurgitation (leakage) are the most common valvular disorders in adults aged 70 years and older. For patients with severe valve disease, heart valve replacement involving open heart surgery can improve functional status and quality of life. A variety of conventional mechanical and bioprosthetic heart valves are readily available. However, some individuals are considered too high risk for open heart surgery. These patients may benefit from a less invasive procedure. Percutaneous heart valve replacement is a relatively new interventional procedure involving the insertion of an artificial heart valve using a catheter, rather than through open heart surgery. The portal of entry is typically either via the femoral vein or artery, or directly through the myocardium via the apical region of the heart. An expandable prosthetic heart valve is delivered and deployed at the site of the diseased native valve. The percutaneous heart valve replacement procedure usually takes less time to perform and is less invasive than open heart surgery. The Agency for Healthcare Research and Quality (AHRQ) has commissioned this Technical Brief to: Describe the types of conventional and percutaneous heart valves now in use or in development and their theoretical advantages and disadvantages for different patient populations; Describe the literature comparing various types of conventional heart valves in adults and determine whether a systematic review of this literature is feasible and needed; Describe the literature evaluating percutaneous heart valves in adults, including the patient populations and major outcomes studied to date; Describe implantation techniques for percutaneous heart valves and the factors associated with surgery or setting that may impact outcomes. The research team further clarified and refined the overall research objectives and the key questions. The key questions addressed are as follows: Question 1. What are the different types of heart valves in use and in development (including tissue, mechanical, and percutaneous valves)? a. What are the existing or potential U.S. Food and Drug Administration (FDA) indications for each valve (patient characteristics, etc.)? b. What are the theoretical advantages and disadvantages of different valves for different patient populations? Question 2. From a systematic literature scan of studies on different types of tissue and mechanical valves, describe the types of comparative studies, including basic study design, size of study, length of followup, and outcomes assessed. This literature scan will provide data to determine if a systematic review of this literature is possible and needed, and to provide needed context for understanding the evaluation and development of percutaneous heart valves. Question 3. From a systematic literature scan of studies on different types of percutaneous heart valves, provide a synthesis of the following variables: a. Number for each type of valve. b. Type of studies—comparative and non-comparative randomized controlled trials (RCTs), non-randomized controlled clinical trials, case series, etc. c. Variables associated with surgery (implantation technique), setting, etc. d. Size of studies/length of followup. e. Patient population/concurrent and prior treatments. f. Hemodynamic success rates reported. g. Harms reported. Question 4. What are the variables associated with surgery or setting that may impact outcomes for percutaneous heart valves? a. What are the different implantation techniques (i.e., position of implantation, delivery, and axis techniques)? What is the evidence of success (i.e., absence of narrowing and regurgitation) and harms? i. For percutaneous aortic valves. ii. For percutaneous mitral valves.
