Multimodality Assessment of Anomalous Aortic Origin of the Right Coronary Artery Presenting With Cardiac Arrest

Abstract

Anomalous aortic origin of coronary artery (AAOCA) can range from benign anatomic variants to those presenting with sudden cardiac arrest. This unique case of right AAOCA demonstrates detailed anatomic findings from cardiac computed tomography and the effects of transient acute coronary ischemia by cardiac magnetic resonance. (Level of Difficulty: Advanced.).
