Ablation for leaky valve with constant atrial fibrillation
This study tests whether a catheter ablation procedure (a way to fix abnormal heart rhythms) can help people who have both constant atrial fibrillation and severe mitral regurgitation (a leaky heart valve). It is for people whose heart valve leak is caused by the rhythm problem, not by valve damage.
