Thromboembolic accident after mitral valve replacement

Between January 1981 and December 2000, we report 112 cases of mitral valvular replacement with bileaflet prothesis. Saint Jude prosthesis was implanted in 71% of cases. With a mean follow-up of 110 months we report a thromboembolic accident in 7 cases (6.2%). The linear rate of thromboembolic accident is 0.69% A/P. This complication was concerned 5 women and 5 men. The mean age is 54 years (43-65 years). An embolic accident without prosthesis thrombosis is noted in 6 cases. We report only one case of prosthesis occlusive thrombosis with urgent chirurgical intervention. Par rapport au RVM, l'ATE est survenue dans uns délai moyen de 129 months (86-168 months). Left atrium size, embolic antecedent, and bad anticoagulation are the predicted factors of thromboembolic accidents in our study. Patient age and sex, atrial fibrillation, type of bileaflet prosthesis don't influence the occurrence of thromboembolic accident.
