The systematic view of ventricular functional mitral regurgitation and the treatment through transcatheter mitral valve edge-to-edge repair / 中国介入心脏病学杂志

ABSTRACT

Mitral regurgitation is one of the most common valvular heart diseases,with a incidence rate of about 10％in the population,most of which are functional regurgitation.V-FMR patients are caused by weakened left ventricular systolic function combined with left ventricular enlargement,resulting in valve ring enlargement and relative tendon tethering.Due to poor cardiac function and basic condition,the surgical risk and prognosis of these patients are not as good as those with conventional mitral regurgitation.In recent years,transcatheter mitral valve edge-to-edge repair has gradually developed into a mature mitral regurgitation intervention technique,achieving good clinical results in V-FMR patients and providing new options for the treatment of V-FMR.
