Del Nido cardioplegia in isolated adult coronary artery bypass surgery.

Background: Del Nido cardioplegia (DC) offers prolonged single-dose myocardial protection in pediatric cardiac surgery. We set out to evaluate the efficacy of DC in adult patients undergoing isolated coronary artery bypass grafting (CABG).

Methods: From January 2012 to October 2017, 851 consecutive isolated CABG surgeries were performed by 2 study surgeons at our center with blood cardioplegia (BC, n = 350), used from January 2012 to April 2014, and DC (n = 501), used from May 2014 to October 2017.
