Impact of effective regurgitant orifice area on outcome of secondary mitral regurgitation transcatheter repair.

ABSTRACT:

Objectives

To assess the value of effective regurgitant orifice (ERO) in predicting outcome after edge-to-edge transcatheter mitral valve repair (TMVR) for secondary mitral regurgitation (SMR) and identify the optimal cut-off for patients' selection.

Methods

Using the EuroSMR (European Registry of Transcatheter Repair for Secondary Mitral Regurgitation) registry, that included patients undergoing edge-to-edge TMVR for SMR between November 2008 and January 2019 in 8 experienced European centres, we assessed the optimal ERO threshold associated with mortality in SMR patients undergoing TMVR, and compared characteristics and outcomes of patients according to baseline ERO.

Results

Among 1062 patients with severe SMR and ERO quantification by proximal isovelocity surface a
