Management of anomalous origin of right coronary artery from left coronary sinus

Area of Science:

• Cardiovascular Surgery
• Congenital Heart Disease
• Anatomical Variations

Background:

• Aberrant coronary artery origin is a rare congenital anomaly.
• It is associated with significant risks, including myocardial ischemia and sudden cardiac death.
• Lesions originating from the opposite sinus of Valsalva pose the highest risk.

Purpose of the Study:

• To report a case of aberrant right coronary artery originating superior to the left coronary cusp.
• To describe the inter-arterial and intramural course of the aberrant vessel.
• To highlight the successful surgical correction via reimplantation.

Main Methods:

• Surgical repositioning and reimplantation of the aberrant right coronary artery.
• Detailed anatomical description of the aberrant vessel's origin and course.
• Post-operative assessment of surgical outcomes.

Main Results:

• Successful reimplantation of the aberrant right coronary artery was achieved.
• The aberrant vessel had a slit-like ostium and an inter-arterial/intramural course.
• The surgical technique proved safe, effective, and reproducible.

Conclusions:

• Aberrant coronary artery origin, particularly with high-risk anatomical features, warrants surgical intervention.
• Coronary artery reimplantation is a safe and effective technique for managing such anomalies.
• This approach offers a reproducible solution for preventing ischemic events.
