Anomalous origin of the right coronary artery from the left anterior descending artery: a rare trifurcation lesion

Key Result

CCTA identified a rare anomalous right coronary artery originating from the proximal left anterior descending artery in a 77-year-old woman with chest discomfort.

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.
