AbstractMechanical circulatory assistance has become a necessary supplement to more conventional means of hemodynamic support as a shortage of donor organs and associated increase in waiting time have contributed to an increased incidence of hemodynamic deterioration in potential transplant recipients. This review summarizes the experience with circulatory support before and after transplantation of the Utah Transplantation Affiliated Hospitals (UTAH) Cardiac Transplant Program and draws conclusions on the efficacy of one program's use of mechanical circulatory support. Between March 1985 and October 1990, 401 patients were accepted for first-time heart transplantation by the UTAH program. One hundred and eighty patients (46%) were supported before transplantation with conventional hemodynamic therapies, 72 patients (18%) with oral enoximone, 96 patients (25%) with intravenous inotropes, and 34 patients (9%) with an intraaortic balloon; nine patients (2%) required centrifugal blood pump circulatory support. Not included in these statistics are 10 patients awaiting transplantation as of October 10, 1990. Thirty-eight candidates (10%) died awaiting transplantation, 329 (84%) received transplantation, and 24 (6%) were removed from the transplantation list for other reasons. Ten patients (3%) required mechanical circulatory support after transplantation with 38% of this group surviving 1 year after after transplantation. No single factor, including either hemodynamic support before transplantation or donor heart ischemic time, was found to be predictive of the need for mechanical circulatory support after transplantation. One-year survival rates after transplantation of patients requiring mechanical circulatory support before transplantation (86%) were not significantly different than for all transplant patients (88%). The experience of the UTAH Cardiac Transplant Program shows that with the judicious use of mechanical circulatory support transplant patients with advanced forms of hemodynamic support can have as equal a probability of survival as patients who undergo elective transplantation.
