IMPROVEMENT OF MITRAL REGURGITATION AFTER CATHETER ABLATION FOR ATRIAL FIBRILLATION

Atrial fibrillation (AF) has been reported to cause left atrial dilatation with dilatation of mitral annulus (MA) which is associated with functional mitral regurgitation (MR). The impact of catheter ablation (CA) for AF on MR remains unknown. We defined significant MR as that with p MR jet
