The Fontan procedure is a staged palliative surgery for children born with a single functional ventricle — congenital heart defects in which one of the heart's pumping chambers is absent or severely underdeveloped. Conditions requiring the Fontan include hypoplastic left heart syndrome (HLHS), tricuspid atresia, double outlet right ventricle, and heterotaxy syndromes.

The Fontan circulation routes blood from the body (systemic venous blood) directly to the lungs, bypassing the single working ventricle entirely. This is achieved in stages: a modified Blalock-Taussig shunt in the neonatal period, a Glenn shunt (superior vena cava to pulmonary artery) at 4–6 months, and the completed Fontan (total cavopulmonary connection, TCPC) at 2–4 years.

India has a small number of centres with the experience and infrastructure to perform the Fontan pathway: AIIMS New Delhi, Apollo Hospitals, Sri Jayadeva Institute (Bangalore), and PGIMER Chandigarh. These centres perform the complete staged palliation with outcomes comparable to international published series.

What is the Fontan Procedure?

The total cavopulmonary connection (TCPC) — the final Fontan operation — directs blood from the inferior vena cava (lower body venous drainage) to the pulmonary arteries using either an intracardiac lateral tunnel or an extracardiac conduit. Combined with the Glenn (superior vena cava to pulmonary artery), this completes a circulation in which all systemic venous blood flows passively to the lungs without passing through the heart.

The Fontan circulation is inherently less efficient than a biventricular circulation — children may have reduced exercise tolerance, and long-term complications include Fontan-associated liver disease, protein-losing enteropathy, and arrhythmia. However, survival into adulthood with reasonable quality of life is now achievable for most Fontan patients.

Who Undergoes the Fontan Procedure?

The Fontan is performed in children with congenital single-ventricle physiology where biventricular repair is not achievable. Ideal candidacy for good Fontan outcomes requires: pulmonary vascular resistance <2 Wood units/m², preserved single ventricle systolic function, unobstructed pulmonary arteries of adequate size, absence of atrioventricular valve regurgitation, and sinus rhythm. Each case is assessed by a specialist paediatric cardiology team.

How is the Fontan Staged Surgery Performed?

Stage 1 (Norwood or BT shunt, neonatal): creates a shunt from the subclavian artery to the pulmonary artery to provide pulmonary blood flow, and reconstructs the aorta if hypoplastic. Stage 2 (Glenn shunt, 4–6 months): the superior vena cava is anastomosed to the right pulmonary artery (bidirectional Glenn), reducing the volume load on the single ventricle. Stage 3 (TCPC/Fontan, 2–4 years): a conduit or baffle tunnels inferior vena cava blood to the pulmonary arteries. A small "fenestration" (hole) in the Fontan circuit is often created to act as a pressure relief valve and allow the child to be weaned from bypass more safely; this can be closed by catheter later.

Procedure Steps

1. Complete pre-operative evaluation: echocardiogram, cardiac MRI, catheterisation to measure pulmonary vascular resistance.
2. Staged surgical planning: timing of each stage based on saturation, growth, and pulmonary vascular resistance.
3. Stage 1: neonatal surgery under cardiopulmonary bypass.
4. Stage 2 (Glenn): typically 4–6 months; off-pump bidirectional Glenn anastomosis.
5. Stage 3 (TCPC): at 2–4 years; extracardiac conduit Fontan with fenestration.
6. Post-operative ICU: specialist paediatric cardiac ICU; pulmonary vasodilator therapy.
7. Fontan fenestration management: catheter-based closure at 1–2 years if saturations permit.
8. Long-term follow-up programme: annual echocardiogram, exercise testing, liver assessment.

The Fontan procedure in India costs $10,000–$18,000 per stage, making the complete three-stage palliation approximately $30,000–$50,000. In the United States, the Norwood alone typically costs $150,000–$300,000 in hospital charges.

Recovery & Follow-up

Each Fontan stage requires 2–4 weeks' hospital stay with paediatric cardiac ICU. The child is typically discharged home on anticoagulation (warfarin or aspirin), diuretics, and sometimes pulmonary vasodilators. Follow-up with a specialist congenital heart disease programme is lifelong.

Recovery Tips

• Anticoagulation must be taken exactly as prescribed; INR monitoring is essential for warfarin.
• Chest physiotherapy aids lung recovery after cardiac surgery.
• Children are typically restricted from heavy contact sports post-Fontan; moderate exercise is encouraged.
• Annual surveillance echocardiogram, liver function tests, and exercise testing are essential.
• Parents should have an emergency action plan and know the signs of Fontan complications (ascites, oedema, deteriorating saturation).

Risks & Complications

Stage 1 (Norwood) carries the highest mortality (5–15% at experienced centres). The Glenn and Fontan stages carry lower risk (1–3% each). Long-term Fontan complications include protein-losing enteropathy, plastic bronchitis, Fontan-associated liver disease (fibrosis/cirrhosis), arrhythmia, thromboembolic events, and eventual heart transplantation need.

Why GAF Healthcare

Gaf Healthcare coordinates the Fontan pathway at India's most experienced congenital cardiac surgery centres. We understand the emotional and logistical complexity of planning multi-stage surgery across years — our coordinators provide dedicated family support throughout the entire surgical journey, from pre-operative evaluation through the complete palliation and ongoing surveillance.

Frequently Asked Questions

How many operations does the Fontan pathway involve?

The complete Fontan palliation involves three operations: a neonatal palliative shunt (Stage 1), a Glenn shunt at 4–6 months (Stage 2), and the completed Fontan/TCPC at 2–4 years (Stage 3). Some patients require additional procedures (catheter interventions, AV valve repair) along the way.

What is the long-term outlook for a Fontan patient?

Outcomes have improved dramatically. 20-year survival rates in contemporary series exceed 80%. Most patients live into adulthood; however, Fontan circulation is not normal and patients require lifelong specialist care.

Can the Fontan be reversed or converted to a biventricular circulation?

A small minority of patients with tricuspid atresia and large enough right ventricle may be suitable for a biventricular conversion (1.5-ventricle repair). Most Fontan patients cannot be converted to a normal biventricular circulation; the Fontan circuit is the definitive palliation.

Is heart transplantation eventually needed for Fontan patients?

A proportion (estimated 20–30% by age 40) of Fontan patients will eventually need cardiac transplantation due to Fontan failure (progressive ventricular dysfunction, protein-losing enteropathy, or Fontan cirrhosis). Transplantation is the definitive treatment for Fontan failure.

Can our child receive the complete Fontan pathway in India?

Yes. The specialist centres we work with in India perform all three stages of the Fontan palliation with surgical and catheter lab teams experienced in single-ventricle management. We coordinate each stage and ensure continuity of care between visits.
