Right coronary translocation for anomalous origin of right coronary artery from the left coronary sinus

Area of Science:

• Cardiovascular Surgery
• Congenital Heart Disease
• Surgical Innovation

Background:

• Anomalous origin of the right coronary artery from the left sinus of Valsalva with an intramural course is a rare congenital coronary anomaly.
• This anomaly can lead to myocardial ischemia and sudden cardiac death.
• Surgical correction is often necessary, with current options including coronary artery bypass grafting or unroofing procedures.

Purpose of the Study:

• To describe a simplified surgical technique, right coronary translocation, for managing right coronary artery originating from the left sinus with an intramural course.
• To evaluate the early and medium-term efficacy of this novel translocation technique.

Main Methods:

• The described surgical procedure involves transecting the right coronary artery distal to its intramural segment.
• The transected artery is then anastomosed to the ascending aorta superior to the right coronary sinus.
• This technique was successfully performed in four consecutive patients.

Main Results:

• All four patients who underwent right coronary translocation demonstrated good early and medium-term clinical outcomes.
• No significant complications or adverse events were reported in the immediate or follow-up periods.

Conclusions:

• Right coronary translocation represents a simplified and effective surgical alternative for treating right coronary artery anomalies with intramural courses.
• This technique provides a valuable option compared to conventional coronary artery bypass or unroofing procedures, with promising results.
