title: [Uncommon cause of malfunction of a valve prosthesis of the the St. Jude Medical type].
abstract: We report the malfunction of a St. Jude Medical prosthetic valve in mitral position in a 60 year old woman. One of the two leaflets of the valve was locked in closed position because of the interference of a chorda tendinea. The patient was asymptomatic and the valve dysfunction was discovered during a routine control examination. The bi-leaflet design of this prosthetic valve appears to have offered some protection to our patient. The malfunction involved only one of the hemi-disc and the haemodynamic derangement was moderate.
