title: Acute bacterial endocarditis with postpartum aortic valve replacement.
abstract: A case of acute bacterial endocarditis with aortic valve abscess, aortic insufficiency, and congestive heart failure at 32 weeks' gestation is described. Prompt valve replacement is indicated due to the risks of embolism to the coronary arteries and brain, and to the high mortality of such patients with medical management only. The infant was delivered prematurely to avoid the intraoperative risks to the fetus of cardiac surgery. General rather than regional anesthesia was chosen because venous pooling from a regional block would necessitate preoperative fluid loading and vasopressor therapy, which would be stressful for an already failing heart. In the presence of severe congestive heart failure, the patient underwent cesarean section and delivered a health 2020-g male infant; 36 hours later the aortic valve was successfully replaced with a no. 21 Byork-Shiley prosthesis. The infecting organism was Streptococcus viridans.
