Outcomes of Del Nido and hyperkalemic blood cardioplegia in adult cardiac surgery with prolonged aortic cross-clamp times★.

Background: The utility and uptake of Del Nido cardioplegia in adult cardiac surgery is rapidly increasing. Cases with prolonged aortic cross-clamp times necessitate multi-dosing however an understanding of safe ischaemic times and definitive guidelines in this domain are lacking. Therefore, this study aimed to assess the safety and efficacy of our DNC strategy by comparing post-operative troponin profiles and clinical outcomes between Del Nido and hyperkalaemic cardioplegia for cases with aortic cross-clamp times of greater than 90 min.

Optimal Conduit Diameter Selection in Coronary Bypass Grafting Using Saphenous Vein.

Background: Predictors of long-term saphenous vein graft (SVG) patency following coronary artery bypass grafting (CABG) include harvesting technique, degree of proximal coronary stenosis, and target vessel diameter and runoff. The objective of this study was to evaluate the association between vein graft diameter and long-term survival.

Methods: Patients undergoing primary CABG (2000-2017) at Flinders Medical Centre, Adelaide, Australia, were categorised into three groups according to average SVG diameter (<3.
