Re-repair Mitral Valve Replacement for Paravalvular Leaks Unsuitable for Catheter Treatment / 日本心臓血管外科学会雑誌

ABSTRACT

We report a case of re-repair mitral valve replacement (MVR) for paravalvular leaks that were unsuitable for catheter treatment. Three years ago, a 67-year-old woman, who had undergone MVR for rheumatic mitral valve replacement at the age of 33 years and undergone re-MVR at the age of 47 years, was admitted with hemolytic anemia. We performed paravalvular leak (PVL) repair directly with 5-0 polypropylene sutures because of calcifications in the annulus. Three years after the operation, she presented with dyspnea on exertion, and transthoracic echocardiography revealed several paravalvular leaks. We consulted with cardiologists in our and other institutions, and these leaks were determined to be unsuitable for catheter treatment. We removed the artificial valve, and found the calcifications and residual cuffs from the first or second artificial valves. These residual cuffs were removed with Cusa® and Harmonic Synergy®. We performed re-repair MVR without reconstruction of the annulus. She was discharged on postoperative day 39 with no complications and did not experience any recurrence of PVL for 2 years. Residual cuffs from the artificial valve may cause PVLs, and Cusa® and Harmonic Synergy® are useful for removing residual cuffs and calcifications.
