[Infective endocarditis associated with pregnancy].

PURPOSE: To report the intra-hospitalar and late follow-up of patients with infective endocarditis (IE) acquired in the pregnancy or puerperium.

METHODS

Eleven patients, between 1984-1992 according to the beginning of the IE episode (fever and other signals) were studied. Patients were divided in two groups: IE of pregnancy (7 cases), and puerperal IE (4 cases).

RESULTS

In the pregnancy IE group, mitral valve was affected in 6 (85%), and aortic valve in 1 (15%). During the course of the treatment, two patients had to be operated on, respectively, in the 24th and 28th week of the pregnancy. The 1st one had a successfully mitral valve replacement by a biological prosthesis but 48 h later she aborted, and the 2nd presented neurological complication (intracerebral hemorrhage) in the immediate post-operative period of a successfully mitral valve replacement by biological prosthesis. She was undergone to a cesarean but the fetus remained alive for 24 h only. If we look at the newborns (fetus), only 4 of them survived. Out of 3 fetal deaths, 2 had close association with mother cardiac surgeries. In the pregnant period acquired IE, 3 (47%) mothers died. In the puerperium group, 2 mitral valves and 2 aortic valves had IE. Two of them had to be operated on due to an important aortic regurgitation and cardiac failure. There were no deaths in this group.

CONCLUSION

During pregnancy, IE showed a high morbi-mortality for mother and concept. The mother's neurological complications played a major role in the poor outcome during the pregnancy period.
