Abstract

A young female patient presenting with a non-ST-segment elevation myocardial infarction underwent invasive coronary angiography, revealing a total occlusion of the right coronary artery. During percutaneous coronary intervention with dual catheter access, a retrograde tip injection and peculiar retrograde wiring unmasked a giant coronary aneurysm, which noninvasive imaging confirmed.

Keywords: acute coronary syndrome; computed tomography; coronary vessel anomaly; hybrid imaging; percutaneous coronary intervention.
