Impact of LV Dilatation on Outcomes of Concomitant Mitral Valve Repair in Patients Undergoing CABG with Moderate Ischemic MR
Key Points
To evaluate the effect of left ventricular (LV) dilatation on the outcomes of concomitant mitral valve repair during coronary artery bypass grafting (CABG) in patients with moderate ischemic mitral regurgitation (MR).
Randomized trial involving patients undergoing CABG with moderate ischemic MR.
Assessment of LV dilatation measured preoperatively and its relation to postoperative outcomes.
Follow-up duration of six months post-surgery.
Patients with significant LV dilatation showed a higher rate of adverse cardiac events (25% vs 10%, p=0.03).
Mitral valve repair success rate was lower in those with LV dilatation (60% vs 90%, p=0.01).
Overall mortality was significantly associated with LV dilatation (HR 2.4, 95% CI 1.3-4.5, p=0.02).
