[Isolated anomalous origin of a septal artery from a third coronary ostium. Apropos of a case].
The authors report the case of a patient undergoing coronary angiography for angina who had an anomalous origin of the septal perforator artery from a separate ostium. Anomalies of the coronary arteries may consist not only of anomalous trajectories and coronary fistulae but also of anomalous origins of the main coronary arteries. The anomalous origin 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 artery provides a collateral circulation for occluded main coronary vessels, thereby preserving left ventricular contractility.
