Abstract
Cardiac transplantation is the definitive surgical treatment for patients with severe left ventricular dysfunction and congestive heart failure. Unfortunately, however, the supply of donor hearts remains severely limited, so transplantation is an option for only a minority of these patients. Even after being approved for a heart transplant, patients often have a long wait until a suitable donor heart can be found. This waiting period entails a significant mortality rate. Because the supply of donor hearts is not expected to increase, surgeons have introduced several alternatives to heart transplantation, including partial left ventriculectomy, mitral valve repair, myocardial revascularization, and endoventricular circular patch plasty. For maximal benefit, surgeons must refine the selection criteria for determining which patients are the best candidates for each of these procedures.
