A Study on the Efficacy and Safety of TEER Combined With Electrical Cardioversion in Patients With Severe Mitral Regurgitation and Atrial Fibrillation
Recruiting now · Not applicable
Conditions studied: Atrial Fibrillation Mitral Valve Insufficiency
In brief
This study aims to evaluate the safety and efficacy of combined electrical cardioversion and TEER in patients with severe mitral regurgitation and atrial fibrillation after undergoing TEER. The main objective is to assess the superiority of the combined treatment strategy in reducing the composite endpoints of all-cause mortality, re-hospitalization for heart failure, and stroke within one year, providing high-quality evidence-based medical evidence to optimize the "structural repair + rhythm control" comprehensive intervention strategy for such patients.
