Abstract: Aberration of the right coronary artery from the left anterior descending is a very rare congenital anomaly.The anomalous the right coronary artery,as a branch of the septal branch,has not been reported clinically.This article reports such rare case.A 52-year-old female was admitted due to"sudden chest pain and confusion for 4 hours".The ECG showed that the ST-segment of leads(V1-V4,V3R,V4R and V5R)were elevated about 0.1-0.3 mVThe blood pressure was 63/53 mmHg.She was diagnosed as cardiogenic shock second to acute anterior and right ventricular ST-segment elevation myocardial infarction.Emergency coronary angiography was performed after intra-aortic ballon pump was implanted to assist circulation.During the treatment of the culprit vessel,it was accidentally found that the right coronary artery,as a branch vessel,originated from the ostium of the second septal branch of the anterior descending artery.
