Abstract

This report describes a case of embolic myocardial infarction secondary to a pulmonary arteriovenous malformation. Pulmonary arteriovenous malformations are rare and mostly congenital and are inherited as an autosomal dominant disorder known as hereditary hemorrhagic telangiectasia. Myocardial infarction is an uncommon complication in patients with untreated pulmonary arteriovenous malformations. (Level of Difficulty: Advanced.).
