['Orthotopic heart transplantation (OHT) remains the gold standard for end-stage heart failure. However, donor availability is severely limited. With a median wait time of 6.6 months and more than 12% of patients waiting 5 or more years, the decision is often made to implant a left ventricular assist device (LVAD) as\xa0a bridge to transplantation for medical stabilization. Furthermore, the number of patients who have had at least one prior sternotomy while awaiting transplantation is increasing. Previous studies have indicated reoperative sternotomy as a risk factor for compromised survival. Concerns are specifically focused on perioperative, short-term, and long-term outcomes after LVAD explantation or redo sternotomy before OHT because of increasing operative complexity. We hypothesize that despite the greater technical difficulty caused by LVAD explantation or redo sternotomy, outcomes would not be compromised.', 'We retrospectively analyzed patients who underwent OHT at the University of Pennsylvania during a 5-year period (2008-2013; n\xa0= 253). All patients who underwent a bridge to transplantation LVAD (n\xa0= 72) or prior sternotomy (n\xa0= 65) were compared with those undergoing OHT with a virgin chest (n\xa0= 116). Preoperative, intraoperative, and postoperative variables were analyzed. Short- and long-term survival were studied (minimum follow-up, 6 months).', 'Comorbidities were similar among the groups. There was no difference in donor allograft ischemic time (p\xa0= 0.6). However, cardiopulmonary bypass time was longer in both bridge to transplantation and prior sternotomy cohorts (p < 0.00001). The blood transfusion requirement was higher in bridge to transplantation (12.5 ± 13.7 units; p\xa0= 0.0007) and prior sternotomy groups (11.7 ± 12.9 units; p\xa0= 0.02) as compared with the virgin chest cohort (7.1 ± 10.7 units). For bridge to transplantation, both time to extubation (1.0 ± 1.6 versus 0.9 ± 1.0 days; p\xa0= 0.03) and intensive care unit length of stay (7.0 ± 7.0 versus 6.0 ± 7.0 days; p\xa0= 0.06) were longer compared with the virgin chest cohort. The same was true for prior sternotomy (extubation time, 1.9 ± 4.4 days; p\xa0= 0.005; intensive care unit length of stay, 8.0 ± 12.0 days; p\xa0= 0.06). There was no difference in hospital length of stay (p\xa0= 0.2). Overall, there was no difference in short- or long-term survival.'] Do prior Sternotomy and Ventricular Assist Device Implantation Adversely Impact Survival or Allograft Function After Heart Transplantation?
