Pulmonary Arteriovenous Malformation and Embolic Myocardial Infarction in a Patient With Hereditary Hemorrhagic Telangiectasia

JACC Case Rep. 2020 Feb 19;2(2):316-318. doi: 10.1016/j.jaccas.2019.11.046. eCollection 2020 Feb.

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.).
