Accessory mitral valve tissue is a rare congenital cardiac
anomaly, and is usually incidentally detected in childhood. In
this case, we present a 65-year-old man with aortic stenosis
originating from an accessory mitral valve leaflet attached to
the anterior mitral leaflet. Interestingly enough, the patients
accessory mitral valve remained undetected for years until he
became symptomatic for degenerative aortic stenosis. Aortic
valve replacement and excision of the accessory mitral valve
attached to the anterior mitral leaflet was performed with a
transaortic approach instead of atriotomy. It was also unusual to
see accessory mitral valve tissue with aortic stenosis instead of
other frequently associated congenital anomalies.
