The fifth redo operation for mitral paravalvular leakage and free-floating closure device extraction: A case report.

Paravalvular leakage (PVL) is a serious complication of prosthetic valve surgery. Surgical and transcatheter methods can be used for treatment. It is rare for closure devices to detach and free float in cardiac chambers. Transcatheter methods can be reused, but surgical treatment is more appropriate if this reuse is due to an increase in PVL. Here, we present a successfully operated case with a closure device freely passing through the PVL from the ventricle to the atrium, after four surgical valve replacements and two transcatheter device closures, owing to infective endocarditis.
