This case report we presented is that the anomalous left main coronary artery （LMCA） originates from the proximal segment of right coronary artery. In order to confirm the origin and course of the anomalous LMCA, a multi-slice computed tomography （MSCT） of the heart was performed on a 64-slice machine （Philips 64 Slice, Philips, USA） after 6 months of coronary angiography operation. The results showed that the anomalous LMCA originates from the proximal segment of right coronary artery, lies posteriorly to the aorta before taking acute sharply to go between the aorta and left atrium. It was classified as R-Ⅱ P subtype according to Lipton＇s classification. It is a rare case in the clinical practice.

single coronary artery （SCA）, defined as an artery that arises from the arterial trunk and nourishes the entire myocardium, is rare. We report two cases of SCA, one is the fight coronary artery （RCA） originating from the middle of left descending artery （LAD）, and the other is the left main coronary artery （LMCA） arising from the proximal fight coronary artery.

coronary artery anomalies are usually encountered as coincidental findings during coronary angiography or at autopsy. Life threatening symptoms, such as arrhythmias, syncope, myocardial infarction, or sudden death, can occur in up to 20% of patients. However, the majority of anomalies (80%) are benign and asymptomatic. A single coronary artery (SCA) is one of the most rarely seen coronary anomalies with an incidence of 0.05%. We report the case of a 55-year old male patient who presented with symptoms of chest pain associated with an acute myocardial infarction. coronary angiography revealed an anomalous left main coronary artery (LMCA) originating from the right coronary ostium, and an occluded distal right coronary artery. The occluded distal right coronary artery was successfully treated by thrombosuction and stenting. In order to confirm the origin and course of the SCA, multi-slice computed tomography (MSCT) of the heart was performed after coronary angiography. MSCT showed that the anomalous LMCA originated from the right coronary artery ostium and then passed the interventricular septum, instead of being intra arterial, and under the right ventricular infundibulum. The anomalous LMCA was classified as R-II S subtype according to Lipton’s classification.

single coronary artery is a coincidental finding during coronary angiography or at autopsy. Although it is a rare condition and most of time has an asymptomatic clinic;prognosis varies. We would like to report a case about percutaneous coronary intervention in a patient who has anomalous single coronary artery arising from right sinus valsalva.
