Minimally Invasive Valve-Sparing Approach for Mitral Leaflet Perforation.

ABSTRACT:

Objective

To describe the case of a 52-year-old man who developed severe mitral regurgitation 4 years after undergoing aortic valve replacement, maze procedure, and mitral vegetation removal during surgery for infective endocarditis; the mitral regurgitation was due to a perforation of the anterior mitral leaflet (A2) identified on transthoracic echocardiography.

Key steps

Key procedural steps included: 1) right minithoracotomy access; 2) adhesiolysis and wedge resection of pleural perforations; 3) leaflet perforation repair with bovine pericardial patch; and 4) annuloplasty ring implantation.

Potential pitfalls

Patch repair can fail if the patch is undersized, poorly positioned, or not well integrated, leading to residual regurgitation or early breakdown. Anterior le
