Abstract:
A case of xenograft valve dysfunction presenting with musical cooing murmur is reported. The patient was a 47-year-old woman and had received mitral valve replacement with porcine xenograft (Carpentier-Edwards 31-M) 10 years before Preoperative echocardiogram showed vibration of a leaflet outside the stent of the bioprosthetic valve. Cardiac catheterization revealed stenosis as well as regurgitation of the bioprosthetic valve. The resected xenograft valve showed a tear which produced regurgitation and musical cooing murmur in one of three pliable leaflets and it also showed pannus formation which caused stenosis.
