Atrial fibrillation and successful transcatheter mitral valve repair using MitraClip

Abstract

Ledwoch and colleagues demonstrated in their article entitled “Impact of transcatheter mitral valve repair using MitraClip on right ventricular remodeling” that right ventricular function improved in most of the patients following MitraClip implantation whereas 20% of them experienced worsening of right ventricular function which associated with worse prognosis, despite the latter cohort achieved comparable improvement in the mitral regurgitation. Given most of the latter cohort had atrial fibrillation, aggressive catheter ablation to improve atrial fibrillation before or after MitraClip implantation might reverse left atrial function as well as improving biventricular function and long-term prognosis.
