A report of a case: Anesthetic management of a parturient with severe thrombotic stenosis of a mechanical aortic valve - An exercise in coordination of subspecialties

The pregnant woman with valvular heart disease presents significant challenges to the obstetric, anesthesiology, and cardiology teams. Although successful outcomes for both mother and fetus are possible with coordinated medical care, the patient with a prosthetic valve who requires systemic anticoagulation provides a dilemma of insufficient anticoagulation leading to valve thrombosis versus the risks of maternal perinatal hemorrhage or fetal effects from oral or parenteral anticoagulants. This case report describes the peripartum management of a patient at 27 weeks' gestation with thrombus on a prosthetic aortic valve.
