Abstract: | We report a new technique for reinforcement of a friable posterior mitral annulus using the anterior leaflet after removing
a calcified artificial ring. A 72-year-old woman underwent mitral valve replacement for mitral stenosis and recurrence of
regurgitation after mitral valve repair at 53 years of age. She had been on chronic hemodialysis for 20 years. The posterior
mitral annulus became highly friable after débridement of the calcified artificial ring. The anterior mitral leaflet was detached
from its annulus and transferred to the posterior annulus to cover the defect. The anterior leaflet was anchored to the posterior
annulus by valve sutures, and mitral valve replacement was performed successfully. Postoperative ultrasonic cardiography revealed
preservation of left ventricular function with no perivalvular leakage. |
