Anomalous origin of left circumflex artery from pulmonary artery

摘要

A 45-year-old gentleman, with no coronary risk factors had a mildly positive exercise stress test. Clinical examination ECG and chest X-ray were normal. Coronary angiogram showed ectatic left anterior descending (Fig. 1A, Video 1) and right coronary artery (Fig. IB, Video 2) collateralizing the left circumflex artery which was seen to drain into main pulmonary artery. A coronary CT angiogram showed an anomalous origin of left circumflex artery from the right pulmonary artery (Fig. 1C and D).
