Technique to avoid left ventricular outflow tract obstruction

Asian Cardiovasc Thorac Ann. 2016 Jun;24(5):493-5. doi: 10.1177/0218492316640127. Epub 2016 Mar 18.

Abstract

Preserving the subvalvular mitral valve apparatus during mitral valve replacement is extremely important to minimize progressive postoperative left ventricular remodeling and dysfunction. We describe a simple and reproducible surgical technique that prevents the complications that can occur after total mitral anterior leaflet preservation.

Keywords: Heart valve prosthesis implantation; Mitral valve; Ventricular function; Ventricular outflow obstruction; left.
