ANOMALOUS ORIGIN OF THE SEPTAL PERFORATOR CORONARY-ARTERY FROM A 3RD OSTIUM - A CASE-REPORT

The authors report the case of a patient undergoing coronary angiograp hy for angina who had an anomalous origin of the septal perforator art ery from a separate ostium. Anomalies of the coronary arteries may con sist not only of anomalous trajectories and coronary fistulae but also of anomalous origins of the main coronary arteries. The anomalous ori gin of a septal artery from a separate ostium is very rare accounting for 0.5% of cases in the medical literature. In some cases, this arter y provides a collateral circulation for occluded main coronary vessels , thereby preserving left ventricular contractility.
