Long-term experiences on cardiac retransplantation in adults

Background: It remains disputed whether cardiac retransplantation should be performed. This study aimed to evaluate our long-term experiences on cardiac retransplantation in adults. Patients and methods: Between March 1989 and December 2004, 2% (28/1290) of cardiac retransplantations were performed. Results: The reasons for cardiac retransplantation were cardiac allograft vasculopathy (n = 13; 47%), primary graft failure (n = 11; 39%), and refractory acute rejection (n = 4; 14%). The 30-day mortality risk was 29% (acute rejection: 50%; primary graft failure: 36%; cardiac allograft vasculopathy: 15%, p = 0.324), compared to 8.5% for primary cardiac transplantation (p < 0.001). The causes of early death were acute rejection (n = 3; 37%), multiorgan failure (n = 3; 37%), primary graft failure (n = 1; 13%), and right ventricular failure (n = 1; 13%). The late mortality rate was 96/1000 patient-years. The causes of late death were acute rejection (n = 4; 50%), cardiac allograft vasculopathy (n = 2; 25%), multiorgan failure (n = 1; 13%), and infection (n = 1; 13%). The 1-, 5-, 10-, and 15-year survival was respectively 78, 68, 54,and38%(primarycardiactransplantation),and46,41,32,and32%(cardiacretransplantation)(p = 0.003).Theshort-termsurvivalforcardiac retransplantation due to cardiac allograft vasculopathy was likely better than primary graft failure and refractory acute rejection (p = 0.09). Conclusion: The overall outcomes of cardiac retransplantation are significantly inferior to primary cardiac transplantation. Cardiac retransplantation should be only performed for selected patients. # 2007 European Association for Cardio-Thoracic Surgery. Published by Elsevier B.V. All rights reserved.
