Abstract

Coronary artery fistula are anomalous connections with coronary vessels or cardiac chambers, potentially resulting in coronary dilatation and pseudoaneurysm formation. We present the case of a 68-year-old woman referred to our institution for a voluminous coronary pseudoaneurysm secondary to coronary artery fistula presenting as a nearly completely obstructive left atrial mass. (Level of Difficulty: Intermediate.).
