The arterial switch operation (ASO) is the definitive surgical repair for transposition of the great arteries (TGA) — a congenital heart defect in which the aorta arises from the right ventricle and the pulmonary artery from the left ventricle, creating two separate parallel circulations rather than the normal series circuit. Without surgical correction, complete TGA is fatal in the first days to weeks of life.
The ASO must be performed in the first 2–4 weeks of life, before the left ventricle (which pumps into the low-resistance pulmonary circulation in TGA) loses its conditioning to support systemic blood pressure. It is one of the most complex and technically demanding operations in neonatal cardiac surgery.
India's specialist neonatal cardiac surgery programmes at AIIMS New Delhi, Apollo Hospitals, and Sri Jayadeva Institute perform the ASO with survival rates of 88–94%, comparable to published series from leading Western centres.
What is the Arterial Switch Operation?
The ASO surgically transposes the great arteries back to their correct positions. The aorta is disconnected from the right ventricle and reconnected to the left ventricle. The pulmonary artery is disconnected from the left ventricle and reconnected to the right ventricle. Most importantly, the coronary arteries — which in TGA arise from the "neo-aorta" (the original pulmonary artery) — must be excised with buttons of arterial wall and reimplanted into the new aortic root. Coronary artery transfer is the most technically demanding part of the operation and is the most common cause of early mortality.
Who Needs an Arterial Switch Operation?
All neonates with complete TGA (D-TGA) require surgical correction. The ASO is performed in the first 2–4 weeks of life (ideally 5–14 days) in neonates with simple TGA. In TGA with VSD, surgery can be deferred slightly (up to 4–6 weeks) as the VSD maintains left ventricular pressure training. Neonates with TGA who present late (>4 weeks) may require LV retraining (pulmonary artery banding + aorto-pulmonary shunt) before the definitive ASO.
How is the Arterial Switch Performed?
The neonate is anaesthetised and placed on cardiopulmonary bypass with deep hypothermic circulatory arrest (cooling the body to 18°C and temporarily stopping all blood flow) to allow the complex coronary transfer in a bloodless field. The aorta and pulmonary artery are divided just above their valves. Coronary arteries are excised with buttons of aortic wall. The pulmonary artery (now "neo-aorta") is reconstructed with the coronary artery transfers. The aorta (now "neo-pulmonary artery") is reconstructed. The vessels are swapped and anastomosed to the appropriate ventricles. The Lecompte manoeuvre brings the neo-pulmonary artery anterior to the neo-aorta. Bypass is weaned and the chest closed.
Procedure Steps
- Pre-operative: urgent echocardiogram; balloon atrial septostomy (Rashkind) to improve mixing and oxygenation.
- Timing: ASO performed at 1–2 weeks of life before LV regression.
- Anaesthesia: specialist neonatal cardiac anaesthesiologist; intra-operative TOE.
- Cardiopulmonary bypass and deep hypothermic circulatory arrest (18°C).
- Aortic and pulmonary artery division.
- Coronary artery transfer: excised with aortic buttons; reimplanted into neo-aorta.
- Lecompte manoeuvre: pulmonary artery brought anterior to aorta.
- Neo-aorta and neo-pulmonary artery anastomoses completed.
- Repair of any associated VSD or ASD.
- Bypass weaned; haemostasis; chest closed; transfer to neonatal cardiac ICU.

The arterial switch operation in India costs $9,000–$16,000 all-inclusive including neonatal cardiac ICU, surgery, and hospital stay of 3–6 weeks. In the United States, hospital charges alone may exceed $300,000.
Recovery & Follow-up
Neonatal recovery after ASO takes 3–6 weeks in the hospital. Most neonates are extubated within 48–96 hours. Residual haemodynamic issues (coronary insufficiency, pulmonary artery stenosis at anastomosis) may require further intervention. Long-term follow-up for neo-aortic root dilation and neo-pulmonary artery stenosis is essential throughout childhood and adulthood.
Recovery Tips
- Neonatal nutrition: early enteral feeding via nasogastric tube; high calorie supplementation.
- Wound care: sternal wound heals in 6–8 weeks.
- Medications: diuretics, digoxin, and ACE inhibitors typically weaned in first 3–6 months.
- Long-term: annual echocardiogram to monitor neo-aortic root and neo-pulmonary artery.
- Exercise restriction: light exercise is fine in childhood; avoid high-intensity competitive sports until cleared by cardiologist.
Risks & Complications
Early mortality after ASO at experienced centres is 3–10% (depending on coronary anatomy complexity). Late risks include neo-aortic root dilation (leading to aortic regurgitation, requiring valve-sparing aortic root surgery in 5–10% by adulthood), pulmonary artery stenosis (requiring balloon dilation or surgery in 5–15%), and coronary artery stenosis at the transfer sites.
Why GAF Healthcare
The arterial switch operation demands the highest level of neonatal cardiac surgical and ICU expertise. Gaf Healthcare works only with centres that perform a minimum of 50+ neonatal cardiac operations annually and have published outcome data. We coordinate emergency medical visa for neonates and family, arrange accommodation adjacent to the hospital, and provide dedicated family support for the prolonged hospital stay.
Frequently Asked Questions
How soon after birth must the ASO be done?
The ASO must be done within the first 2–4 weeks of life. After this window, the left ventricle begins to regress (loses mass) as it only pumps against the low-resistance pulmonary circuit. A regressed LV cannot support systemic circulation and a two-stage approach (LV retraining followed by delayed ASO) becomes necessary.
What is the Rashkind balloon atrial septostomy?
Rashkind septostomy is an emergency catheter procedure performed in the first hours of life to tear open the foramen ovale, creating mixing between the parallel circulations and improving oxygenation. It keeps the baby stable until the ASO can be performed.
Are there any long-term problems after the arterial switch?
Most ASO survivors live normal lives. Long-term risks include neo-aortic root dilation (requiring surveillance and occasional surgery), pulmonary artery anastomotic stenosis (catheter-treatable), and very rarely coronary ostial stenosis.
Can TGA be detected before birth?
Yes. Foetal echocardiography at 18–22 weeks can detect TGA. Prenatal diagnosis allows planned delivery at a centre with neonatal cardiac surgery, improving outcomes significantly compared to emergency postnatal diagnosis.
Will my child be able to lead a normal life after ASO?
The vast majority of children who undergo ASO have a normal or near-normal quality of life, attend regular school, participate in physical education, and live into adulthood with routine cardiac surveillance.
