Cardiac Structural Anomalies and Repair

Since the initiation of the UTAH Cardiac Transplant Program, echocardiography has been used to evaluate 74 potential donors including 65 of 71 hearts ultimately used for transplantation. Of these 65 donors, 46 had normal studies, nine had pericardial effusions, five had mild septal hypokinesia with otherwise normal function, four had equivocal mitral valve prolapse, and only one heart could not be visualized. All transplants were successful and all donor hearts exhibited satisfactory hemodynamic function immediately after transplantation, including the hearts that were mildly abnormal before transplantation. These hearts included 21 (29%) that could have been excluded by conventional screening criteria. Nine potential donor hearts with grossly abnormal echocardiograms were not used for transplantation, including eight hearts with severe hypokinesia and one heart with significant mitral and tricuspid regurgitation. Inspection or histologic analysis confirmed the presence of severe dysfunction or morphologic damage in those hearts subjected to these additional measures. We conclude that echocardiographic screening is a useful method of evaluating potential cardiac transplant donors. It can identify potential donors that would otherwise have been excluded and it can identify potential donors with severe cardiac dysfunction without the need for direct surgical inspection.
