Arterial switch operation for transposition of the great vessels

The arterial switch operation (Switch Operation) is a complex cardiac surgical procedure performed in newborns diagnosed with transposition of the great arteries (TGA). The operation restores normal blood circulation, ensuring adequate oxygen delivery to organs and tissues.

When is the operation required?

• In transposition of the great arteries – abnormal positioning of the aorta and pulmonary artery.
• In cases of impaired blood oxygenation, when the body does not receive sufficient oxygen.
• In the presence of associated congenital heart defects, such as a ventricular septal defect (VSD).
• In emergency situations when medical therapy cannot maintain adequate blood oxygen levels.

How is the operation performed?

1. Diagnostics and preparation – echocardiography, MRI, CT angiography, and cardiac catheterization.
2. General anesthesia and connection to cardiopulmonary bypass.
3. Arterial switch – the aorta and pulmonary artery are transected and reattached to the correct ventricles.
4. Coronary artery transfer – a critical step to ensure proper myocardial blood supply.
5. Hemodynamic control and chest closure – restoration of circulation and final stabilization.

Main advantages of the arterial switch operation in Belarus

• Radical correction of the defect – the heart functions in a physiological mode.
• High survival rates and excellent long-term outcomes.
• Preservation of normal cardiac function without the need for frequent reoperations.
• Reduced risk of long-term complications – patients can lead a full and active life.

The procedure is performed in leading cardiac surgery centers in Belarus using modern technologies. Experienced surgeons ensure a high success rate, while specialized rehabilitation programs support optimal recovery.
