An unexpected cause of angina detected by ECG-gated cardiac computed tomography.
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.
