This full-color atlas with accompanying video DVD provides a complete and practical "how-to" guide to planning and performing mitral valve repair surgery for mitral regurgitation. The book reviews the natural history of mitral regurgitation, the functional anatomy of the mitral valve, and the use of echocardiography in preoperative evaluation and surgical planning. Chapters describe and illustrate all techniques currently used for mitral valve repair and discuss results. A bound-in DVD presents narrated video clips of six cases that show the application of specific techniques. Each case begins with preoperative echocardiograms demonstrating the mitral valve defect and proceeds through key surgical maneuvers.

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.

Mitral valve disease is widely prevalent among pediatric and adult population across the world, and it encompasses a spectrum of lesions which include congenital valve defects, degenerative valve lesions, and valve dysfunction due to secondary pathologies. Though replacement of the diseased mitral valves with artificial heart valves has been the standard of care until early 1990's, current trends have veered towards complete surgical repair. These trends are encouraging, but current repair techniques are plagued with lack of durability and high rates of failure within 10 years after repair. With increasing number of patients receiving mitral valve repair, there is now an immediate need to understand the mechanisms of repair failure, and assess the role of several clinical risk factors on valve repair. In this thesis, an in vitro pulsatile left heart simulator was developed to mimic the congenital and adult mitral valve pathological morphologies in normal porcine valves, and simulate the pathological valve hemodynamics and mechanics. Different surgical repair techniques were used to correct the valve lesions, and the post repair valve hemodynamics, mechanics and geometry were assessed using quantitative measurement techniques. The extent to which each repair restores physiological valve function and mechanics was assessed, and the impact of different pathological risk factors on repair failure mechanisms was investigated. It is expected that the knowledge from this thesis would play an important role in the evolution of mitral valve surgical repair, and guide the development of more effective and long-lasting heart valve repair technologies.

It also includes tools for repairing the chordae tendinae, resecting a portion of the valve, applying MV material properties, boundary conditions and exporting these as an Abaqus (.inp) file where the simulation is carried out. The results of these simulations ultimately serve as biomechanical markers for identifying the best surgical method to be used.

The tricuspid valve, which is located on the right side of the heart, prevents blood backflow from the right ventricle to the right atrium. Regurgitation in this valve occurs when its leaflets do not close normally. Tricuspid valve regurgitation is one of the most common tricuspid valve dysfunctions, often requiring valve repair or replacement. The long-term success rate of the repair surgeries has not been promising; in many cases, reoperations are required within a few years after the first surgery. A limiting factor in understanding the etiology of tricuspid valve repair failure is our lack of knowledge regarding tricuspid valve biomechanics. In particular, tricuspid valve mechanical behavior has not been accurately studied. In addition, there is no precise analytical and/or computerized model to predict the mechanical responses of the valve under normal and pathological conditions. In the current study, we have used biaxial tensile testing, small angle light scattering, ex-vivo passive heart beating simulation, and sonomicrometry techniques to quantify the mechanical characteristics, microstructure, dynamic deformations, and geometric parameters of the tricuspid valve. We aimed to develop a more accurate computerized model of the tricuspid valve for simulation purposes. Our studies are important both for understanding the normal valvular function as well as for development/improvement of surgical procedures and medical devices.
