Abstract

A conus artery is sometimes a good collateral source for the left anterior descending coronary artery and the right coronary artery (RCA). In some cases, the conus artery arises independently of the RCA from a separate orifice, which is called an isolated conus artery. The conus artery is often missed by angiography for RCA if a catheter is deeply engaged. This case report describes a percutaneous coronary intervention of chronic total occlusion of the proximal RCA with good collateral circulation from an isolated conus artery by super-selective ipsilateral injection via the artery.
