Implication

Supports CCTA for rare coronary anomaly detection in symptomatic elderly; extends known variants of RCA from proximal LAD.

Key Points

A dominant right coronary artery originating from the left anterior descending artery is rare.
Cardiac computed tomography angiography identified this abnormality during evaluation for chest discomfort.
The artery courses between the aorta and right ventricular outflow tract, then reaches its normal path.
This unique trifurcation lesion underscores potential implications for cardiac interventions.

Intervention

Cardiac computed tomography angiography (CCTA)

Outcome

Anatomical findings on CCTA
