title: An unexpected cause of angina detected by ECG-gated cardiac computed tomography.
abstract: Until recently anomalous coronary artery anatomy was only identified either by coronary angiography, at autopsy, or during cardiac surgery. With recent developments in the area of cardiac imaging, ECG-gated cardiac computed tomography (CT) has emerged as a minimally invasive modality to delineate both coronary anatomy and pathology. We present a case of an anomalous right coronary artery origin from the ascending aorta detected by ECG-gated cardiac CT in a 47 year-old male who presented to the emergency department complaining of acute chest pain after intense exercise. Given its relatively non invasive nature, ECG-gated cardiac CT may assist in the diagnosis and management of patients with atypical chest pain in which more invasive diagnostic examinations (i.e. coronary angiography) are not warranted.
