PREDICTORS OF HEART FAILURE DEVELOPMENT IN ATRIAL FIBRILLATION PATIENTS WITH FUNCTIONAL MITRAL REGURGITATION

Functional mitral regurgitation (MR) can occur as a result of atrial dilatation in patients with atrial fibrillation (AF), and concomitant MR is associated with worse outcomes. However, risk factor of congestive heart failure (CHF) in AF patients with functional MR has not been determined. In
