Anomalous origins of left anterior descending and circumflex coronary arteries from separate orifices in the right coronary sinus.
A case is described of a 69-year-old man with angina pectoris who was found at coronary angiography to have all three coronary arteries arising by separate orifices from the right coronary sinus. This appears to be a previously unreported anomaly. The embryological origin and mechanisms of angina in coronary arterial anomalies are discussed.
