Partial Left Ventriculectomy: Its Theory, Results and Perspectives(v.1173 International Congress S.)

This proceeding of the first Symposium features every aspects of partial left ventriculectomy , including original concept by Batista, theoretical analysis and actual observation using strain gages, pressure-volume relationship and stress-strain relationship. These theoretical background are follwed by clinical experiences by pioneers from Brazil (Batista), United States (Cleveland Clinic, Buffalo General Hospital) and others. i) Original concept outlined by the pioneer, Randas JV Batista, MD ii) Basic and clinical research that shed lights into the mechanism of the Batista operation. iii) Clinical experiences by pioneers from Curitiba, Buffalo and Cleveland Despite the fact that cardiac transplantation has been established as the last measure to resort, there has been an ever increasing gap between those who need it and those who actually benefit from it. Partial left ventriculectomy has been developed in Brazil to be employed in areas where heart transplantation has been limited because of donor shortage, socio-economical reasons or both, namely in the world to fill the gap. This proceeding scopes not only the clinical experiences by the pioneers but also the theoretical analyses on clinical cases and effects of isolated mitral valve repairs, focusing the mechanism of action and risk-benefit of the epoch-making procedure. The proceeding is designed to fill the gap between the lay press and scientific publications, that slag way behind the interest of physicians, scientists and patients with severe heart failure. Although the Symposium is the first of such, it includes either pros or cons of the procedure, providing invaluable information for cardiologists and surgeons who are planning to start the procedure and will be giving hope for those with heart failure awaiting or rejected from heart transplantation.
