Abstract

The anomalous origin of the right coronary artery from the main pulmonary artery has been rarely reported. We report a 63-year-old male with angina pectoris who was shown to have an anomalous origin of the right coronary artery from the main pulmonary artery. The abnormal origin was identified by conventional coronary angiography, but the abnormal course of the artery was precisely delineated by high resolution multi-slice computerized tomography. The patient underwent successful surgical correction of the anomalous vessel with complete resolution of symptoms.

  Fig. 1 Imaging studies of the patient. A: coronary angiography demonstrated retrograde filling of the right coronary artery from the left coronary artery during the venous drainage phase. B: a cardiac computerized tomogram showed that the right coronary artery originated from the main pulmonary artery and the left coronary artery originated from the aortic root. The RCA ostium was not detected by MDCT. C: a myocardial thallium scan showed mixed myocardial ischemia and infarction in the RCA territory. D: cardiac computerized tomogram checked after the operation showed a patent bypass graft vessel and closure of the RCA originated in the main pulmonary artery. RCA: right coronary artery, MDCT: multi-detector computed tomography.
