Abstract

Introduction: There is not enough data in the literature regarding the safety and efficiency of del Nido cardioplegia in patients with prolonged cross-clamping time. This study aims to determine the efficacy and safety of del Nido cardioplegia compared to cold blood cardioplegia in patients with prolonged aortic cross-clamping time.

Methods: In this retrospective study, patients with an aortic cross-clamping time ≥ 90 minutes were included. One hundred consecutive adult patients undergoing cardiac surgery using del Nido cardioplegia comprised the study group, and 100 consecutive adult patients undergoing cardiac surgical procedures using cold blood cardioplegia comprised the control group. Propensity score matching yielded 88 del Nido cardioplegia and 88 cold blood cardioplegia patients.

Results: There were no significant differences when comparing the matched groups regarding the requirement for intraoperative defibrillation, postoperative peak troponin T levels, inotropic support, intra-aortic balloon pump requirement, and left ventricular ejection fraction at discharge and on the sixth postoperative month; also, there were no significant differences when comparing cardiopulmonary bypass time and total operation time. Mean cross-clamping time was significantly shorter in the del Nido group (P<0.001).

Conclusion: Del Nido cardioplegia may be a safe alternative to cold blood cardioplegia in adults undergoing cardiac surgical procedures with prolonged aortic cross-clamping time.
