Mitral valve replacement with papillary muscle tugging approximation in a patient with severely impaired left ventricular function 14 years after initial mitral valve repair

The best treatment for ventricular functional mitral regurgitation still remains unclear. Papillary muscle tugging approximation (PMTA) is a technique known to preserve function of the sub-valvular apparatus, keeping it functionally in synch with the left ventricle systolic and diastolic dynamics.

description The best treatment for ventricular functional mitral regurgitation still remains unclear. Papillary muscle tugging approximation (PMTA) is a technique known to preserve function of the sub-valvular apparatus, keeping it functionally in synch with the left ventricle systolic and diastolic dynamics. Herein, we present a case of mitral valve replacement with PMTA in a patient with severely impaired left ventricular function 14 years post initial mitral valve repair, which significantly improved during a course of 4 years after the reoperation without any complications.
