Early mitral valve repair surgery versus active surveillance in asymptomatic severe primary mitral regurgitation-insights from the Dutch AMR registry.

ABSTRACT:

Background

Management of asymptomatic severe mitral regurgitation (MR) is challenging. Both early mitral valve repair surgery and active surveillance with facilitated surgery are possible strategies. The DutchAMR registry compares clinical outcomes between these two strategies.

Methods

Patients were included between 2013-2019. Primary endpoints were cerebrovascular accidents (CVA), reoperations, and mortality. Facilitated surgery was defined as mitral valve repair surgery performed after developing a surgical indication during active surveillance.

Results

Ninety-nine patients were enrolled; 71 in active surveillance and 28 in early surgery. Over a median follow-up time of 5.1 years, 51% of active surveillance patients underwent facilitated surgery due to ESC guideline
