Microplegia vs 4:1 Blood Cardioplegia: Effectiveness and Cost Savings in Complex Cardiac Operations.

Background: Microplegia has been studied during isolated coronary artery bypass grafting and valve surgery but not in more complex operations. Objectives of this study were to demonstrate safety and effectiveness of microplegia relative to Buckberg cardioplegia during these operations.

Methods: From January 2012 to January 2017, 242 patients underwent multicomponent operations with simplified microplegia delivered via syringe pump and 10,512 with modified Buckberg cardioplegia.
