Imaging findings
Coronary CT angiography demonstrates five distinct vessels arising anomalously from the right coronary cusp. These include a conus branch, the right coronary artery (RCA), a transseptal branch coursing through the septum, a retroaortic left circumflex artery, and a prepulmonic left anterior descending (LAD) artery that branches into multiple diagonals.
Key takeaways
Multiple anomalous coronary artery origins from a single coronary cusp is a rare congenital variant. CT angiography is highly effective for delineating the precise courses of these anomalous vessels, which is critical for planning interventional or surgical management.
