Mechanical Circulatory Support During Surgical Revascularization for Ischemic Cardiomyopathy

This study aimed to describe the use of perioperative mechanical circulatory support (MCS) and its impact on outcomes in patients with ischemic cardiomyopathy undergoing surgical revascularization. Between 2015 and 2021, data from 378 patients with an ejection fraction below 35 percent and undergoing isolated coronary artery bypass grafting (CABG) were analyzed based on utilization of MCS—no MCS, preoperative MCS and postoperative MCS. Authors included patients requiring intra-aortic balloon pump, extracorporeal membrane oxygenation, or Impella device within the MCS groups. The primary outcome was operative mortality.
