Prognostic value of preprocedural 6-min walk test in patients undergoing transcatheter mitral valve repair—insights from the German transcatheter mitral valve interventions registry

Aims The 6-min walk test (6 MWT) has been established as an important tool for functional assessment in heart failure patients. However, its prognostic impact on the outcome in subjects with mitral regurgitation undergoing transcatheter mitral valve repair is unknown. Methods This present work repre...

Description
Summary:Aims The 6-min walk test (6 MWT) has been established as an important tool for functional assessment in heart failure patients. However, its prognostic impact on the outcome in subjects with mitral regurgitation undergoing transcatheter mitral valve repair is unknown. Methods This present work represents a sub-analysis of the German, prospective, multicenter, Transcatheter Mitral Valve Interventions (TRAMI) registry. Of the main study cohort ( n  = 828) 326 patients underwent 6 MWT prior to the procedure. Patients were assigned to two groups depending on the preprocedural 6 MWT distance using the median (
