Abstract

Background: Chronic ischemic mitral regurgitation (CIMR) presents a surgical dilemma: repair or replace the mitral valve during coronary artery bypass grafting (CABG).

Aim of the work: This study investigates early outcomes following mitral valve repair versus replacement during CABG for CIMR patients.

Methods: The study employed a retrospective design, enrolling 100 patients who underwent CABG surgery with either mitral valve repair or replacement at the National Heart Institute. Patients were stratified into Group I (repair) and Group II (replacement). Further stratification within each group categorized patients by mitral regurgitation (MR) severity (moderately severe or severe).

Results: This analysis of mitral valve repair versus replacement during CABG for chronic IMR (n=100) reveals trade-offs. Younger patients opted for replacement (p=0.005), which, though associated with lower post-operative ejection fraction (p=0.044) and extended ICU (p=0.043) and hospital stays (p=0.001) for severe IMR, showed significant dyspnea improvement for most groups (p

Conclusions: Mitral valve repair and replacement during CABG for chronic IMR appear viable options, but early outcomes suggest potential trade-offs. Replacement in younger patients with severe CIMR might come with a lower postoperative ejection fraction and longer recovery times.
