Urgent aortic valve replacement for infective endocarditis during the 23rd week of pregnancy.

Infective endocarditis is a rare but serious complication of pregnancy with high maternal and fetal mortality. Surgical intervention is an option when medical therapy fails. We report the case of a 23-year-old female with severe aortic valve regurgitation and hemodynamic compromise related to acute bacterial endocarditis of a congenital bicuspid aortic valve during the 23rd week of pregnancy. She underwent urgent aortic valve replacement and, despite implementation of known fetal-protection strategies, fetal demise occurred.
