[Mitral valve replacement with a bileaflet prosthesis: results of 112 cases].

We report 112 cases of mitral valvular replacement with bileaflet prothesis. The mean age is 40 ans +/- 3.4 years (9-74 years). 71 (65%) are men and 45 (35%) are women, the main éthiology of mitral disease is rheumatic fever (94.74%). The Saint Jude prothesis is implanted in 70.4% cases. The early post operator mortality is 1.8% it is related on low cardiac output. With a mean follow-up of 110 months, the late mortality is 5.5%. The survey is 97% at 5 years and 94% at 10 years. The rates of thromboembolic and hemorrhagic complications are 6.3% and 9%. We report only one case of infective endocarditis. The rate of réintervention is 5%. By echocardiography the hemodynamic profile of bileaflet prothesis is excellent even with the small size.
