Bridge to heart transplantation: importance of patient selection.

Abstract

Since 1986, 26 candidates were evaluated for mechanical support as a bridge to heart transplantation. Group 1 consisted of 15 patients who were accepted and who received support with a ventricular assist device (14 patients) or a total artificial heart (1 patient). Seven of the 15 patients received transplants and survived, whereas contraindications to transplant developed in seven patients while they were receiving support, and these seven died. One patient remains hospitalized after transplantation. Group 2 consisted of 11 patients rejected for circulatory support because of renal insufficiency or infection (9), pulmonary embolus (1), and cerebrovascular accident (1). Two group 2 patients underwent transplant procedures after their complications resolved, and one survived. One other group 2 patient who recovered without transplantation or mechanical support was discharged. There was no significant difference in age, gender, or cause of cardiogenic shock between the two groups. Four of five patients accepted for mechanical support on the first evaluation survived, and three of 10 accepted after the initial evaluation survived, indicating that delayed selection often results in complications that preclude transplantation and survival. Only one of the 26 patients survived without transplantation or support. These data emphasize the importance of patient selection on the outcome of bridging to transplantation.
