Mitral valve surgery combined with on-pump versus off-pump myocardial revascularization: A prospective randomized analysis with midterm follow-up.

Background: The aim of the study was to compare results off-pump coronary artery bypass (OPCAB) combined mitral valve reconstruction (MVR) with standard on-pump approach.

Methods: From January 2014 to December 2017, a total of 53 patients received a combined myocardial revascularization and MVR for multivessel coronary artery disease (CAD) complicated by severe ischemic mitral regurgitation (IMR). All the subjects were divided into two groups: group I: 27 patients, received OPCAB + MVR, and group II (control group): 26 patients with on-pump myocardial revascularization (ONCAB) + MVR.
