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.
莱多赫及其同事在题为“经导管二尖瓣修复术对二尖瓣夹合术对右心室重构的影响”的文章中表明，大多数接受二尖瓣夹合术的患者的右心室功能得到改善，而其中 20%的患者的右心室功能恶化，尽管后者在二尖瓣反流方面取得了可比的改善。鉴于后者大多数患者患有心房颤动，在二尖瓣夹合术之前或之后进行积极的导管消融以改善心房颤动，可能会逆转左心房功能，改善双心室功能和长期预后。
