Transcatheter Mitral Valve-in-Valve Replacement With Balloon-Assisted Translocation in Calcified Mitral Anterior Leaflet.

ABSTRACT:

Objective

A significant anatomical limitation of transcatheter mitral valve replacement (TMVR) is the risk of left ventricular outflow tract obstruction. Here, we describe balloon-assisted translocation in mitral anterior leaflet (BATMAN) in a patient with a calcified bioprosthetic mitral valve.

Key steps

The anterior mitral leaflet is traversed with a 0.014-inch stiff wire with electrocautery, followed by the delivery of a long sheath and placement of dual wires. The dual-wire system allows for BATMAN, followed by a rapid delivery of the transcatheter heart valve, minimizing exposure to significant mitral regurgitation.

Potential pitfalls

Leaflet traversal with a 0.035-inch system may be difficult because of leaflet calcification, and translocation of the anterior mi
