Impact of Warm Ischemia Time on Survival After Heart Transplantation

Abstract Background There is little data available on the specific effects of warm ischemia time (WIT) as opposed to cold ischemia or storage time. With current research endeavors focusing on warm continuous perfusion, storage of donor hearts, and utilization of hearts from non–heart-beating donors, the impact of WIT on outcomes is increasingly relevant. The aim of this study was to analyze our results in cardiac transplantation with specific focus on the impact of WIT. Methods A retrospective review of 206 patients who underwent orthotopic heart transplantation at our institution between June 2001 and November 2010 was performed. Donor, recipient, and operative factors were analyzed. The main outcome variables were all cause mortality, survival, and primary graft failure. Results WIT of >80 minutes was associated with reduced survival compared with a shorter WIT of
