Introduction
Combined heart–liver transplantation (CHLT) has resulted in acceptable survival rates compared to orthotopic liver transplantation (OLT) alone and orthotopic heart transplantation alone. Using the US transplant registry, we compared outcomes following sequential and combined HLT.
Methods
We conducted a retrospective cohort study. De-identified data were obtained from the United Network Organ Sharing Registry. The primary outcome was patient survival from the date of OLT. Secondary outcomes included liver allograft survival and heart allograft survival.
Results
The study cohort included 301 CHLT recipients and six sequential heart–liver transplantation (SHLT) recipients. Patient survival after CHLT was 88% at 1 year, 84% at 3 years, and 82% at 5 years compared to 83%, 67%, and 50% in the SHLT group (p = 0.010). Liver allograft survival at 1, 3, and 5 years was 88%,83% and 82%, respectively, in the CHLT group compared to 83% and 67%, and 50%, respectively, in the SHLT group (p = 0.009). After OLT, heart allograft survival at 1, 3, and 5 years was 86%, 79%, and 74% in the CHLT group, respectively, compared to 83%, 67%, and 50% in the SHLT group (p = 0.037).
Conclusions
Despite the limited size of the SHLT cohort, we found that CHLT was superior to SHLT in survival rate and graft survival. The better outcomes noted in CHLT may relate to immunoprotection provided by liver transplantation from the same donor.
