Clinical and echocardiographic outcomes of combined CABG and MV repair

Key Points

Patients showed significant improvement, with 94.7% achieving NYHA class II status post-discharge.
The elimination of residual mitral regurgitation occurred in 97.1%, highlighting successful intervention.
The approach involved patients undergoing CABG with mitral valve repair, emphasizing mixed-method observational findings.
The findings suggest support for CABG and MV repair as a viable treatment despite patient comorbidities.

Abstract

A mixed-method observational study evaluated patients undergoing Coronary Artery Bypass Grafting (CABG) with mitral valve (MV) repair for moderate to severe mitral regurgitation (MR). Most patients aged between 61–70 years (46.3%) and with 60% being male, 73% with Type 2 diabetes and 83.33% with triple-vessel coronary artery disease (CAD) (83.8%) and 15% with left main CAD. At discharge, 94.7% improved to NYHA class II and residual MR was eliminated in 97.1% patients. This study demonstrates significantly improved 12-month outcomes, with elimination of residual MR, supporting CABG with concomitant MV repair as a viable option for IMR patients despite high comorbidity.
