[Intercoronary anastomoses of congenital origin. Apropos of a case].
Homo- or heterolateral intercoronary anastomoses are usually present in the normal heart. Owing to their small caliber they cannot be visualized at coronary arteriography, but they may become visible in case of obstructive coronary lesion. Congenital intercoronary anastomoses are entirely different. A case of intercoronary anastomosis between the right coronary artery and the circumflex artery, without any coronary lesion, is presented. This is an exceptional variant, only 12 cases of which were found in the literature. The anastomosis was located in the atrioventricular sulcus in 11 cases and in the interventricular sulcus in 1 case. This "abnormality" can be distinguished from collateral arteries by its angiographic features, and it does not reflect an underlying coronary disease. It may play a protective role if lesions develop on one of the two vessels it links together.
