Transection and Relocation of Anomalous Left Coronary Artery After Aborted Sudden Cardiac Death

Area of Science:

• Cardiology
• Congenital Heart Disease
• Cardiac Surgery

Background:

• Anomalous origin of the left main coronary artery from the right coronary sinus is a rare congenital heart defect.
• This anomaly is a known cause of sudden cardiac death, particularly in young individuals.

Observation:

• A young adult patient presented with a history of aborted sudden cardiac death.
• Diagnostic evaluation revealed anomalous origin of the left main coronary artery from the right coronary sinus.

Findings:

• The patient underwent surgical repair involving the translocation of the left coronary artery to the left coronary sinus of Valsalva.
• The procedure resulted in an excellent clinical outcome at the 10-year follow-up.

Implications:

• Complete anatomical repair is an effective treatment for anomalous origin of the left main coronary artery.
• Successful surgical intervention can prevent sudden cardiac death and ensure long-term survival for patients with this anomaly.
