Anomalous origin of the right coronary artery: diagnosis and treatment

Area of Science:

• Cardiology
• Cardiac Surgery
• Anatomical Variations

Background:

• Congenital anomalies of the coronary arteries are uncommon but can lead to significant cardiovascular events.
• The right coronary artery (RCA) typically arises from the right aortic sinus.

Observation:

• A rare case involving the right coronary artery (RCA) originating from the left aortic sinus with a single ostium shared with the left coronary artery.
• The patient experienced documented episodes of inferior ischemia attributed to this anomaly.

Findings:

• Surgical intervention using a right internal thoracic artery (RITA) to RCA bypass graft was performed.
• Ligation of the anomalous vessel was also conducted as part of the surgical strategy.

Implications:

• The surgical treatment successfully stabilized coronary blood flow, resolving the ischemia.
• This case highlights the importance of recognizing and surgically managing rare coronary artery anomalies for favorable clinical progress.
