[The risk of cerebrovascular complications in the combination of pregnancy and mitral valve prolapse]. / Le risque d'accidents vasculaires cérébraux au cours de l'association grossesse et prolapsus valvulaire mitral.

ABSTRACT

A case of left intraventricular thrombus, developed from a myxoid mitral valve and revealed by embolic cerebral vascular accidents at the end of a pregnancy, is reported. The links between a mitral valve prolapse and cerebral vascular accidents of embolic origin are studied during pre- and post-partum periods, where coagulation alterations are reviewed. It appears that, in pregnant women with a mitral valve prolapse, there is a maximum risk of developing an intra-cardiac thrombus in the last four weeks of pregnancy or immediately after delivery; this justifies, during that time, a thorough sonocardiographic monitoring.
