Intraoperative Transvalvular Regurgitation Immediately After Mitral Bioprosthetic Valve Implantation

BIOPROSTHETIC VALVES are being used increasingly1 because of their excellent durability2,3 and lesser need for anticoagulation.4 Bioprosthetic valve dysfunction, such as pannus formation, thrombosis, calcification, and endocarditis, may occur in the months or years after valve replacement.5 However, intraoperative issues regarding newly implanted bioprosthetic valves themselves are extremely rare, and only a few cases have been reported.6-9 Here, we present 2 cases of significant mitral bioprosthetic valve regurgitation that occurred immediately after valve implantation while the patients were on cardiopulmonary bypass (CPB).
