Coronary angiography revealed total occlusion of the distal right coronary artery with a unique accessory coronary ring that provided retrograde collateral flow to the left ventricle, demonstrating the importance of considering non-native vessels when identifying target lesions.<br />Competing Interests: Dr Drachman has received consulting fees for Boston Scientific, Broadview Ventures, Cardiovascular Systems Inc, and Cordis not relevant to the current submission.
