Gebiet: Chirurgie Abstract: Background: Preservation of cardiac grafts for transplantation is not standardized and most centers use a single administration of crystalloid solution at the time of harvesting. We investigated possible benefits of an additional dose of cardioplegia dispensed immediately before implantation. – – Methods: Consecutive adult cardiac transplantations (2005?2012) were reviewed. Hearts were harvested following a standard protocol (Celsior 2L, 4?8°C). In 2008, 100 ml crys-talloid cardioplegic solution was added and administered immediately before implanta-tion. Univariate and logistic regression analyses were used to investigate risk factors for post-operative graft failure and mid-term outcome. – – Results: A total of 81 patients, 44 standard (?Cardio???) vs. 37 with additional cardiople-gia (?CardioC?) were analyzed. Recipients and donors were comparable in both groups. CardioC patients demonstrated a reduced need for defibrillation (24 vs. 48%, p D0.03), post-operative ratio of CK-MB/CK (10.1_3.9 vs. 13.3_4.2%, p D0.001), intubation time (2.0_1.6 vs. 7.2_11.5 days, p D0.05), and ICU stay (3.9_2.1 vs. 8.5_7.8 days, p D0.001). Actuarial survival was reduced when graft ischemic time was >180 min in Cardio?? but not in CardioC patients (p D0.033). Organ ischemic time >180 min (OR: 5.48, CI: 1.08?27.75), donor female gender (OR: 5.84, CI: 1.13?33.01), and recipient/donor age >60 (OR: 6.33, CI: 0.86?46.75), but not the additional cardioplegia or the observation period appeared independent predictors of post-operative acute graft failure. – – Conclusion: An additional dose of cardioplegia administered immediately before implan-tation may be a simple way to improve early and late outcome of cardiac transplantation, especially in situations of prolonged graft ischemia.A large, ideally multicentric, randomized study is desirable to verify this preliminary observation.
