CTICasesIntracameral Right Coronary Artery
Imaging findings
Coronary CT angiography demonstrates an anomalous course of the right coronary artery (RCA) where it leaves the AV groove and courses directly within the cavity of the right atrium before returning to its normal course.
Key takeaways
An intracameral coronary artery is a rare congenital anomaly where a segment of the artery courses within a cardiac chamber (typically the right atrium). While usually benign and asymptomatic, it must be recognized to avoid accidental injury during catheter ablation or surgery.
