CTICasesHigh Origin of the Right Coronary Artery
Imaging findings
CT performed as a PE study shows the right coronary artery arising from the ascending aorta well above the sinotubular junction, near the level of the pulmonary artery, then descending to its usual course.
Key takeaways
A high takeoff of the right coronary artery above the sinotubular junction is an innocuous coronary variant that causes no problem in itself, but it is worth recognizing before procedures such as aortic cross-clamping or catheterization so the anomalous origin is anticipated.
