Reversible pulmonary hypertension and high-output heart failure triggered by pregnancy in a patient with congenital arteriovenous malformation: A case report.

Background: Arteriovenous malformations rarely cause congestive heart failure. Pregnancy may in theory trigger heart failure associated with congenital arteriovenous malformations leading to secondary pulmonary hypertension, but no cases have been reported proving that condition.

Methods And Results: We report a 23-year-old pregnant woman at 36 + 5 weeks of gestation requiring urgent medical care because of shortness of breath.
