Clinical Trial: Catheter Ablation for Functional Mitral Regurgitation in Persistent Atrial Fibrillation: Development and Validation of a Predictive Model-A Multicenter Prospective Cohort Study

U.S., Aug. 1 -- ClinicalTrials.gov registry received information related to the study (NCT07096219) titled 'Catheter Ablation for Functional Mitral Regurgitation in Persistent Atrial Fibrillation: Development and Validation of a Predictive Model-A Multicenter Prospective Cohort Study' on July 24.

Brief Summary: Mitral Regurgitation (MR) is the most prevalent type of valvular heart disease in clinical practice, with an average prevalence of approximately 1% in populations with moderate-to-severe or worse MR, which increases significantly with age. Functional MR (FMR) is one subtype of MR and can be further classified into atrial FMR, ventricular FMR, and mixed FMR based on its underlying mechanisms. Pathophysiologically, FMR is closely asso...
