Abstract
Coronaries arise normally from the aortic sinus which consists of one anterior and two posterior cusps of which the right coronary artery (RCA) arises from the anterior cusp and the left coronary artery arises from the left posterior cusp. Abnormal origin of coronary arteries is very rare and counts for about 2.33% of prevalence and below 1% incidence and are comparatively very difficult to diagnose through routine investigations. Till date, only one case has been reported in the literature where the culprit vessel was the victim as seen in our case. We report a case of a 68-year-old male, who underwent coronary angiography for his anginal chest pain, was diagnosed with coronary artery disease with an "abnormally arising RCA" from the left coronary cusp with a proximal stenotic lesion in the anomalously arising RCA, which was confirmed on multidetector computed tomography three-dimensional reconstruction volume-rendered imaging.
