Abstract:

OBJECTIVE

To assess the feasibility of correcting moderate ischemic mitral regurgitation (MR) simultaneously with myocardial revascularization in patients with coronary artery disease (CAD) complicated by impaired left ventricular (LV) contractility.

MATERIAL AND METHODS

We analyzed postoperative outcomes in 68 patients with complicated form of CAD, impaired LV contractility (ejection fraction <30%) and concomitant moderate ischemic MR who underwent coronary artery bypass grafting (CABG) alone or in combination with mitral valve (MV) repaird. Mean follow-up period was 39.3±8.3 months.

RESULTS

The highest prognostic significance for delayed MR recurrence after myocardial revascularization and mitral annuloplasty was observed for posterior wall thickness, transverse left atrium (LA) dimension, damage to S4 and S5 segments of lateral and posterior (lower) LV walls >50% of thickness and LV ejection fraction identified by preoperative cardiac magnetic resonance imaging (MRI).

CONCLUSION

LV posterior wall thickness and transmural cicatricial changes of the same localization detected by cardiac MRI demonstrate the greatest prognostic significance regarding progression or recurrence of MR in long-term period after surgical treatment.
