title: Coronary Artery Pseudoaneurysm due to Medial Mucoid Degeneration Mimicking an Intra-atrial Mass.
abstract: Coronary artery aneurysms are frequently asymptomatic and may be difficult to diagnose by cardiac imaging. We herein present a case of a coronary artery aneurysm of the right coronary artery due to medial mucoid degeneration mimicking an intra-atrial mass on echocardiography and magnetic resonance imaging, with the cause being diagnosed after surgery.
