Impact of Sinus Rhythm Restoration on Mitral Regurgitation in Patients With Atrial Fibrillation: A Comparative Echocardiographic Study

Restoration of sinus rhythm is associated with significant improvement in functional MR, potentially reducing the need for surgical intervention. These findings suggest that rhythm control should be considered in managing patients with AF and significant MR, as it may lead to improved cardiac function and better clinical outcomes. Further large-scale prospective studies are needed to determine the most effective management strategy for functional MR in the context of AF.
