Papillary Muscle Tugging Approximation for Functional Mitral Regurgitation

Abstract

The surgical approach is challenging for patients with severe functional mitral regurgitation with nonischemic/ischemic dilated cardiomyopathy who are unsuitable for heart transplantation or ventricular assist device implantation. We developed a new surgical treatment named papillary muscle tugging approximation combined with mitral valve replacement. This technique is safe and feasible, with excellent midterm outcomes.
