Demonstrates the feasibility of transradial PCI using a double-anchoring technique for complex CTOs in anomalous coronary arteries.
Successful transradial PCI in rare anomalous high-takeoff RCA CTO; leaves open generalizability beyond selected cases.
Percutaneous coronary intervention (PCI) via a transradial approach has become feasible for the treatment of chronic total occlusion (CTO). However, abnormalities such as anomalous origin coronary arteries represent the most technically challenging cases for interventional cardiologists. In this case, we describe a CTO in a rare anomalous right coronary artery (RCA) that originated from a high anterior takeoff with downward direction; transradial recanalization was the second attempt at RCA CTO and was successfully performed by employing a double-anchoring technique with an antegrade and retrograde approach.

Fang et al. (2009) conducted a case report in Chronic total occlusion in an anomalous right coronary artery (n=1). Transradial percutaneous coronary intervention with double-anchoring technique and retrograde guidance was evaluated on Successful recanalization. Transradial percutaneous coronary intervention using a double-anchoring technique and retrograde guidance successfully recanalized a chronic total occlusion in a rare anomalous right coronary artery.
