Ventilator-assisted transcatheter edge-to-edge mitral valve repair for severe atrial functional mitral regurgitation: a case report.

ABSTRACT:

Background

Atrial functional mitral regurgitation (AFMR) is an entity of mitral regurgitation (MR) in atrial fibrillation (AF) with dilated left atrium (LA) and/or normal left ventricular function. Transcatheter edge-to-edge mitral valve repair with MitraClip is reportedly an effective therapy for AFMR. However, performing MitraClip for patients with such condition is challenging because of its characteristic morphology.

Case summary

An 80-year-old man with permanent AF and severe MR was hospitalized for heart failure with preserved ejection fraction. On echocardiography, a marked dilation of the LA caused the anterior mitral leaflet to flatten along the mitral annulus (MA) plane. The posterior mitral leaflet was tethered towards the posterior left ventricle, thus producing
