Abstract

We present a unique case of acute coronary syndrome (ACS) secondary to external coronary artery compression from a left ventricular outflow tract pseudoaneurysm in a postsurgical aortic valve replacement (AVR) patient, subsequently sealed with a pericardial patch. We highlight this rare presentation of ACS in postsurgical AVR patients and the importance of multimodality imaging and treatment of this unique, potentially serious sequela. (Level of Difficulty: Intermediate.).

Keywords: ACS, acute coronary syndrome; AVR, aortic valve replacement; CT, computed tomography; LAD, left anterior descending; LCX, left circumflex; LV, left ventricle; LVOT, left ventricular outflow tract; MRI, magnetic resonance imaging; RCA, right coronary artery; TEE, transesophageal echocardiogram; left ventricular outflow tract; non-ST-segment elevation; pseudoaneurysm.
