Coronary circulation if significantly diseased usually develop collaterals between the distal portion of the diseased vessel and the normal artery to accomplish flow in vessel distal to the diseased segment. These collaterals can be intracoronary or intercoronary. Coronary collaterals have to be differentiated from intercoronary continuity, which is a very rare variant of coronary circulation usually seen in angiographically normal looking arteries. In our patient, although proximal left anterior descending artery revealed significant lesion but intercoronary continuity was seen between normal right coronary artery and left circumflex artery on angiography.
