“…A previous analysis of the Joint ISHLT/United Network for Organ Sharing Thoracic Registry suggested that the outcome following RTx was significantly affected by the time between transplants, where an inter-transplant interval of less than 2 years resulted in a 2-year survival less than 60% (19). Furthermore, an analysis of data in the Cardiac Transplant Research Database showed that survival following RTx were lowest for acute rejection (32% and 8% at 1 and 5 years, respectively) and early graft failure (50% and 39% at 1 and 5 years, respectively) (20). In another report from Columbia University, the authors reported that since 1993, when selection criteria for RTx excluded those with primary allograft failure and intractable acute rejection occurring less than 6 months after HTx, 1-, 2-and 4-year survival following RTx was 94%, 94% and 94%, respectively (24).…”
