Balloon aortic valvotomy in pregnancy.

Severe aortic stenosis in pregnancy has been known to have a high maternal and perinatal mortality, documented at 17 and 32%, respectively, in 1978. More recent reviews still indicate significant maternal morbidity and unfavourable fetal outcomes. Severe aortic stenosis with or without symptoms leads the table of ‘high maternal and fetal risk’ in valvular heart disease in pregnancy. We report the case of a woman with congenital aortic valve stenosis from a progressively stenotic congenital bicuspid aortic valve, successfully treated by balloon aortic valvotomy at the beginning of the second trimester.
