Endocarditis infecciosa de la válvula mitral en gestante

Infective endocarditis is a rare complication of pregnancy with high maternal and fetal mortality. We report the case of a 26-year-old woman with acute bacterial endocarditis of a rheumatic mitral valve in the 28th week of pregnancy. Echocardiography revealed a mobile vegetation of 20 mm length on the posterior leaflet of the mitral valve with subsequent severe mitral regurgitation. The patient responded favorably to a 5-week course of antibiotic therapy, and there were no signs of fetal repercussions. As an intercurrent complication, she was diagnosed with a mycotic aneurism of the femoral artery in the 33rd week of pregnancy. Antenatal corticosteroids for fetal lung maturation were administered, followed by surgery. This case illustrates the importance of a multidisciplinary approach, which, in our patient, allowed term delivery with favorable maternal and fetal outcomes.
