Prevention of left ventricular outflow tract obstruction in transapical mitral valve replacement: the MitraCut procedure.

ABSTRACT:

Background

The MitraCut procedure employs beating heart transapical (TA) cannulation and endoscopic scissors for dividing the anterior mitral leaflet (AML) to prevent left ventricular outflow tract (LVOT) obstruction in transapical transcatheter mitral valve replacement (TA-TMVR).

Aims

We present the first multicentre experience of the MitraCut procedure prior to TA-TMVR to prevent LVOT obstruction.

Methods

In 6 European centres, the clinical outcomes of all 13 high-risk patients who had undergone the MitraCut procedure during TA-TMVR procedures were retrospectively reviewed regarding technical success, procedural details and outcome.

Results

The MitraCut procedure was successfully completed in 11 patients with 1 cutting attempt, while 2 patients had 2 cutting
