Book Description :

These studies have shown that: (1) Sinus flow dynamics are highly sensitive to valve-root interaction. (2) Decreased flow and shear stress in valve-in-valve procedures indicate a higher risk of leaflet thrombosis secondary to flow stasis, perhaps more so in the non-coronary sinus. (3) Patient’s low coronary arteries can dictate the optimal transcatheter aortic valve types to mitigate coronary obstruction risk. (4) Inflow tissue ingrowth and calcification – that are inherently patient-specific - greatly influence valve-in-valve performance due to dynamic effects that result in an anomalous performance different than that seen in vivo. (5) Comparing patient-specific models with idealized rigid models, valve hemodynamics were drastically different mainly in terms of the turbulence associated with every model and to every valve type. The intellectual merit of this study is the development of new mechanistic understanding about (a) how aortic sinus flow patterns are altered after TAVR affecting therefore flow stasis regions (b) how TAV types whether balloon expandable short profile valves or self-expandable long profile valves and valve deployment positions alter sinus flow characteristics and (c) how patient-specific parameters such as sinus geometries and valve and leaflet calcification distribution patterns affect main flow, sinus flow patterns and adverse effects in TAVR and ViV. This proposed research lays groundwork for knowledge that can be translated to update the currently adopted clinical guidelines beyond bench studies.

Book Description :

Transcatheter Valve Repair discusses all aspects related to percutaneous and established valve repair methods. The book is divided into few major sections covering all four valves and other topics. Each section contains several chapters discussing everything related to that valve. Beginning with the pulmonary valve, since it was the first valve to be tackled in the catheterization laboratory, and then moving to the aortic, then the mitral and then finally end with the tricuspid valve. 1.5M US citizens alone have some degree of aortic valve stenosis, with half (750K) requiring aortic valve replacement. Aortic valve replacement, on the whole, is performed by surgeons, requiring bypass machines and technicians, as well as the usual operating team. The operation is expensive and occupies a considerable amount of operating room time. Mostly, the aortic valve is calcified and the usual option available to patients is valve replacement with a variety of choices, ranging from porcine valves to synthetic, for which there are many manufacturers. It should be noted that the aortic valve is the most problematic of valves. Percutaneous procedures are the answer. The bottom line is that given the growing elderly population, many more patients will require valve repair, thus increasing health care costs with not only surgical operations but also hospitalisation. Percutanous valve repair, whilst requiring a cath lab team, does not involve bypass machines nor extended hospitalisation. Like percutaneous transluminal coronary artery interventions (PTCA) has replaced coronary artery bypass grafts (once the golden standard), and now stenting having replaced PTCA and its balloons. We now see drug eluting stents replacing ordinary stents (though at a much higher cost. There will be a huge movement toward percutanous valve repair, which should presumably cut costs but also morbidity and mortality.

Book Description :

Cardiovascular disease is the major cause of morbidity and mortality worldwide. While the past 40 years have brought major progress in cardiac valve repair and replacement, there remain large patient populations that do not receive such therapies. This, in turn, implies a great need for future basic, applied, and clinical research and, ultimately, therapeutic developments. Heart Valves is a state-of-the-art handbook dedicated to: 1) cardiac valve anatomy, 2) models for testing and research methods; 3) clinical trials; and 4) clinical needs and applications.

Book Description :

This book provides comprehensive information on transcatheter aortic valve implantation (TAVI), which was introduced for the treatment of aortic valve disease less than two decades ago. It explains how TAVI has delivered satisfactory results even in high and intermediate risk patients and outlines how it continues to evolve, thus requiring awareness of state of the art approaches to indication, risk stratification, device choice, procedure, and follow-up. In addition, it reports on the complex and multidisciplinary approach needed to maximize the efficacy, safety, and appropriateness of TAVI, providing detailed clinical, interventional and surgical perspectives focusing on the development of this cardiovascular intervention. Starting with the history of TAVI, addressing the interventional anatomy of aortic valve disease, and reporting on the expert authors’ day-to-day experiences, this highly informative book offers an essential update for all cardiologists and surgeons interested in transcatheter aortic valve implantation, as well as any clinician, decision-maker and stakeholder involved in patient selection, procedural management, and follow-up.

Book Description :

"Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure that repairs the valve without removing the old, damaged valve. TAVR is reserved for those patients for whom an open heart surgery procedure is not an option due to age and overall health. Most of the patients that are good candidates for this procedure are over 70 years old. The TAVR programs are multi-disciplinary units with nurses at the front. The NPs and CNSs are responsible for setting up the programs and ensuring that the right candidates are chosen to participate by conducting patient screenings, gather medical records, schedule pre-diagnostic testing and setting up appointments, and communicating with all physicians. Over 200,000 procedures have been performed in the first decade of innovation. TAVR is poised to become the standard of care for most patients with aortic stenosis. The maturity of the technology is not matched with the availability of practical tools for allied health professionals working in this complex field. The authors are international leaders in TAVR program development and have the collective expertise to fill this gap. The primary objective for this text is to serve as the "go-to" resource for TAVR programs development and organization of the clinical evaluation pathway. To date, this information has been conveyed by the author group through conference proceedings, didactic industry-sponsored sessions or social networking on a limited basis. The author team has received repeated requests for the information conveyed. This reference text will be highly sought after by clinicians and industry partners. It will become the recognized standard resource across centers"--Provided by publisher.

Book Description :

Much has evolved in the field of aortic valve disease because of the increase in knowledge in the last decade, especially in the area of its management. This book "Aortic Valve" is comprised of 18 chapters covering basic science, general consideration of aortic valve disease, infective endocarditis, aortic sclerosis and aortic stenosis, bioprosthetic valve, transcatheter aortic valve implantation and a special section on congenital anomalies of the aortic valve. We hope this book will be particularly useful to cardiologists and cardiovascular surgeons and trainees. We also believe that this book will be a valuable resource for radiologists, pathologists, cardiovascular anesthesiologists, and other healthcare professionals who have a special interest in treating patients with aortic valve disease. We are certain that information in this book will help to provide virtually most new areas of aortic valve disease that will be employed in the current era.
