Interrupted Aortic Arch Surgery
Interrupted Aortic Arch (IAA) surgery is a highly specialized cardiac procedure performed to treat a rare but serious congenital heart defect in which the aorta is not fully developed and remains disconnected. The aorta is the main artery that carries oxygen-rich blood from the heart to the rest of the body. When this artery is interrupted, it can lead to life-threatening complications in newborns and infants.
At CureU Healthcare, we connect patients with leading pediatric cardiac surgeons and internationally accredited hospitals in India that specialize in complex congenital heart surgeries, including Interrupted Aortic Arch repair.
What is Interrupted Aortic Arch?
Interrupted Aortic Arch is a rare condition that occurs in about 3 in every 1 million live births. It is classified into three types depending on where the aorta is interrupted:
- Type A Interruption occurs after the left subclavian artery.
- Type B Interruption occurs between the left carotid and left subclavian artery (most common).
- Type C Interruption occurs between the innominate and left carotid artery (rarest).
Symptoms of Interrupted Aortic Arch
Symptoms typically appear soon after birth as the ductus arteriosus (a temporary fetal blood vessel) begins to close. Warning signs include:
- Severe difficulty in breathing
- Bluish skin color (cyanosis)
- Poor feeding or inability to gain weight
- Weak pulses in the lower body
- Extreme lethargy
- Signs of heart failure
Diagnosis of Interrupted Aortic Arch
Early and accurate diagnosis is crucial. Pediatric cardiologists use advanced imaging techniques such as:
- Echocardiogram (ultrasound of the heart)
- CT angiography
- Cardiac MRI
- Chest X-ray and ECG for supporting evaluation
Interrupted Aortic Arch Surgery – The Procedure
The main goal of Interrupted Aortic Arch surgery is to restore continuity of the aorta and ensure normal blood circulation. The surgery typically includes:
- General Anesthesia The baby is placed under anesthesia for a painless procedure.
- Cardiopulmonary Bypass A heart-lung machine temporarily takes over the function of the heart and lungs.
- Aortic Reconstruction The surgeon reconnects the interrupted parts of the aorta, usually by direct anastomosis (sewing them together) or using a patch or graft if needed.
- Closure of Associated Defects Since IAA often occurs with ventricular septal defect (VSD) or patent ductus arteriosus (PDA), these defects are repaired in the same surgery.
- Weaning from Bypass The heart is restarted and normal circulation is restored.
Postoperative Care and Recovery
After surgery, babies are closely monitored in the pediatric intensive care unit (PICU). Recovery care includes:
- Ventilatory support for breathing
- Intravenous medications to support heart function
- Careful monitoring of oxygen levels and blood pressure
- Gradual transition to oral feeding
Risks and Complications
Although Interrupted Aortic Arch repair has high success rates in advanced centers, risks may include:
- Bleeding or infection
- Narrowing of the aortic repair site (re-coarctation)
- Residual heart defects
- Rhythm disturbances
- Need for additional surgeries later in life
Long-Term Outlook
Children who undergo successful IAA surgery often lead healthy, active lives with normal growth and development. Regular cardiology follow-ups are necessary to monitor:
- Blood pressure
- Heart rhythm
- Growth of the aortic repair site
- Any late complications
Cost of Interrupted Aortic Arch Surgery in India
One of the advantages of choosing India for congenital heart surgery is the balance between world-class expertise and affordability.
- In Western countries, costs may range between $80,000 $150,000.
- In India, the cost typically ranges between ₹4.5 8 lakh (USD 5,500
Why Choose India for Interrupted Aortic Arch Surgery?
