Purpose: To evaluate cardiac recipient survival and incidence of coronary artery vasculopathy (CAV) in recipient hearts that have been exposed to lung preservation solution, Perfadex.
Methods: The UNOS database from 2007-2014 was retrospectively reviewed for: 1) donor hearts procured alone or 2) procured with lungs was performed. For donor hearts procured with lungs, hearts were a grouped by exposure or no exposure to Perfadex. Weighted Inverse-propensity scores were used to control for the baseline covariates of donor/recipient age, gender, diabetes, African America (AA), and ischemic time. Survival curves for five-year survival and time to CAV were compared using the generalized Wilcoxon test.
Results: Of 22,337 donor hearts, 8,360 (37.4%) were procured with lungs with 7,386 (88.4%) of them exposed to Perfadex. The remaining 13,977 (62.6%) of donor hearts were procured alone and were not exposed to Perfadex. The majority of these donor hearts were male (D/R), not AA, and not diabetic. Heart-only recipients and donors were younger than donors procured with lungs (28.2 vs. 27.9 and 43.5 vs. 47.9 years (y).
5 year survival for donor hearts procured with lungs is 0.763 (95% CI: 0.752, 0.775) vs 0.744 (95% CI: 0.735, 0.753) for donor hearts procured without lungs (p=0.0098). In donor hearts procured without lungs the probability of not having a CAV at 5 years post-transplantation was 0.943 (95% CI: 0.938, 0.948) vs 0.930 (95% CI: 0.922, 0.938) in donor hearts procured with lungs (p=0.0084). Those that were not exposed have nearly 96% chance of being free from a CAV versus a 92.8% if they were exposed (p= .0009) at 5y. Conclusion: Donor heart exposed to perfadex have a higher 5y incidence of CAV.
