Best Doctors for Fontan Procedure in Delhi NCR, India

By the time a family reaches a Fontan they are usually choosing a unit rather than a city. Delhi NCR holds several of the longest-running paediatric cardiac programmes in India, which matters for an operation that needs following for decades.

1. Units That Handle the Whole Pathway

Not every hospital with a children's heart programme takes on staged single ventricle surgery. It needs a team comfortable from a newborn first stage through to Fontan completion, and comfortable managing what comes afterwards.

Ask how many Fontan completions the unit performs each year, and how many Fontan patients they currently follow. The second answer tells you whether the long-term service exists.

2. Intensive Care Depth

Children come out of a Fontan with a circulation that behaves unlike a normal one, and the first week is where that gets managed. Fluid balance, chest drainage and lung pressures need people who see this physiology regularly rather than occasionally.

Ask whether the intensive care unit is paediatric and cardiac, who covers it overnight, and whether extracorporeal support is available if your child deteriorates.

3. The Easiest Region to Reach, Twice

Indira Gandhi International takes direct flights from much of the Middle East, Central Asia, and East and West Africa. For many families that means one flight rather than two.

You will make the journey twice, and the second time your child will be weeks out of open-heart surgery.

4. Assessment Can Start Before You Fly

Fontan eligibility rests on pressures measured inside the heart. Catheterisation reports and imaging can be reviewed remotely, and the honest answer is sometimes that a child is not yet ready.

Receiving that by email is far better than after a long flight with a small child.

5. The Honest Trade-off

Air quality across the NCR is poor from roughly late October to January, and that window is also the respiratory infection season. Both matter more for a child recovering from a Fontan than for almost any other patient, because you will be in the region for weeks after discharge.

About §7 sets out what to discuss. None of it justifies delaying urgent treatment.

1. What This Page Covers

This page deals with having a Fontan completion in Delhi NCR: the units, the length of stay, the timing, the costs and what to watch for.

For the operation itself, including the physiology, the three-stage pathway, eligibility criteria, surgical technique, fenestration and the long-term complications, see Fontan surgeons across India, which sets all of that out in full. A procedural account is also available at how the operation is performed.

In short, the Fontan routes blood from the lower body straight into the lung arteries, bypassing the heart, so a single working ventricle only has to pump to the body. Blood reaches the lungs passively rather than by a pump.

2. It Is Palliation, Not Cure

This belongs on every page about this operation, not only the main one.

The Fontan does not create a normal heart and it is not a repair. It improves oxygen levels substantially, allows better growth, and greatly extends life. It also leaves a circulation that is not normal and that tends to wear over decades.

A proportion of children who have a Fontan need a heart transplant in adulthood, commonly in their twenties, thirties or forties. That is the known long arc of the condition rather than a failure of the surgery.

Ask the unit to explain the realistic long view for your child specifically. A team that will not have that conversation is the wrong team.

3. Where the Units Are

Paediatric cardiac programmes in the region operate at several established centres, spread across the NCR rather than clustered in central Delhi:

• Fortis Escorts Heart Institute, Okhla, Delhi

• Indraprastha Apollo Hospital, Delhi

• Apollo Hospitals, New Delhi

• Fortis Memorial Research Institute, Gurugram

• Medanta, Gurugram

• Marengo Asia Hospitals, Faridabad

Not all of them take on the same volume of single ventricle work. The listing on this page shows which unit each specialist works at, and the question to ask any of them is how many Fontan completions they do each year and how many Fontan patients they currently follow.

4. Whether Your Child Is Ready

Eligibility turns on numbers measured inside the heart rather than on how well a child looks. A unit is looking for a successful second stage already behind you, low resistance and low average pressure in the lung blood vessels, a single ventricle still pumping adequately, no significant valve leak, and lung arteries of adequate size.

Where lung vessel pressures are too high, a Fontan carries a high risk of failing, and proceeding regardless is not a kindness.

Ask what your child's actual measurements were. If the answer is that they are not yet ready, ask what would need to change and when reassessment would happen. The country-level page sets out the criteria in more detail.

5. Expect Assessment to Be Repeated on Arrival

Send the catheterisation report, imaging and operation notes from the earlier stages before you travel, so the unit can give an opinion on eligibility in advance.

Expect that catheterisation will be repeated in India if the existing study is more than roughly six months old, or if your child's condition has changed. That is not duplication for its own sake. The decision to proceed rests on current pressures, and an out-of-date number is not a basis for opening a child's chest.

Budget for it in both time and money. A separate catheterisation admission before surgery adds days to your stay and a line to your estimate.

6. How Long You Will Be in the Region

Longer than almost any other children's heart operation, and longer than most families plan for.

Published guidance for this procedure indicates fourteen to twenty-one days in hospital, including around five to seven days in paediatric cardiac intensive care, followed by four to seven weeks of outpatient monitoring nearby.

Total time in the region is therefore commonly six to ten weeks. Short flights may sometimes be cleared around six weeks, and long-haul international flights are typically cleared at eight to ten.

Clearance to fly is written and conditional, resting on a stable circulation, acceptable oxygen levels in room air, fluid collections resolved or minimal, a healed wound, blood-thinning treatment stable at target, and your child feeding and gaining weight. Never book a return flight around the discharge date.

7. Timing, Air Quality and Infection Season

Air quality across the NCR is poor from roughly late October to January, and that period is also the respiratory infection season. For a Fontan child this matters more than for most patients, and for two specific reasons.

The first is exposure. You will be in the region for four to seven weeks after discharge, so a winter admission means weeks of it rather than days. Children recovering from this operation often have fluid around the lungs and lower oxygen levels than usual, which makes respiratory irritation less easily tolerated.

The second is postponement. A child who develops a respiratory infection before surgery will usually have the operation deferred, which extends your stay and your costs. That is more likely in winter.

February to April and September to October are the more comfortable months, and May and June are very hot. Where surgery is elective, raise timing with the surgeon. Where a child's oxygen levels are falling, the heart decides and not the calendar.

8. Cost, and What It Excludes

Published figures put the Fontan procedure in India at roughly 8,000 to 15,000 US dollars, indicative published ranges checked in August 2026 rather than quotes, covering the core surgical hospitalisation.

Confirm any figure in writing with the hospital. Ask for it itemised, and ask specifically whether these are inside it:

• A separate catheterisation admission on arrival

• Any catheter intervention before surgery, such as treating narrowed lung arteries

• Extended intensive care, or prolonged chest drainage

• Later closure of a fenestration, if one is created

• Accommodation for the four to seven weeks after discharge

• A stay for both parents across the whole period

• Flights, and reviews after you return home

The accommodation line is the one families underestimate most. Six to ten weeks of housing for two adults in the NCR is a substantial share of the total and is rarely inside a surgical package.

9. Warning Signs While You Are Still Here

You will spend four to seven weeks in an apartment in the NCR with a child recently out of a Fontan. Knowing what should prompt a call, and what should prompt going straight back to hospital, matters more in that setting than it would at home near your own paediatrician.

Contact the unit immediately, or go to the emergency department, if you see:

• Breathing that becomes faster or more laboured

• Oxygen levels falling below the range the team gave you at discharge

• Swelling of the abdomen, face or legs, or rapid weight gain over a day or two

• Fever, or redness, swelling or discharge from the wound

• Unusual bruising, nosebleeds, or blood in stool or urine, while on blood-thinning treatment

• Persistent vomiting, or diarrhoea that does not settle

• Unusual drowsiness, irritability, or a child who simply is not themselves

Ask for a written list of thresholds before discharge, including the oxygen saturation figure below which you should call, and the direct number to reach the unit outside working hours. Do not accept a general reassurance in place of numbers.

Weigh your child daily on the same scales and write it down. Rapid weight gain is often the first sign that fluid is reaccumulating, and it shows up before breathlessness does.

10. Delhi NCR Is Not One City

The region covers Delhi plus Gurugram, Noida, Faridabad and Ghaziabad, and the units are spread across it. Two hospitals both described as being in Delhi NCR can be two hours apart in traffic.

This matters more here than for almost any other procedure. You will return every one to two weeks for outpatient review, for up to seven weeks, with a child who tires easily and should not be spending hours in a car.

Find out exactly which city your unit is in and stay within a short drive of it. Nothing else about the location matters by comparison.

11. Six to Ten Weeks in the NCR With a Child

The practicalities need settling before you fix dates, because this is a longer trip than most families have ever taken.

India's medical visa route allows accompanying attendants, generally up to two, applied for alongside your child's visa with a hospital invitation letter and cost estimate. A stay of six to ten weeks may exceed the initial visa period, so raise extension at the application stage rather than discovering it in week seven. Some nationalities must apply in person at an embassy rather than online.

Book accommodation with a kitchen. Over two months with a child on a low-fat diet, being able to cook is not a comfort but a requirement.

Ask the hospital about parent facilities directly: whether one of you can stay overnight on the ward, visiting arrangements in intensive care, and somewhere to prepare food. Decide about siblings and schooling before you commit, because two months is most of a term.

12. Follow-up After You Fly Home

Fontan follow-up does not taper off. It continues through childhood, adolescence and adult life, and it is how the late problems get caught early enough to manage.

Before leaving the region, collect the operation note, the discharge summary, all imaging, the blood-thinning plan with target levels, a medicine list with doses, the low-fat diet guidance in writing, and a follow-up schedule stating what falls due when.

Ask whether the NCR unit will review echocardiograms and blood results sent from home, at what intervals, and how that is arranged. Also ask what adult congenital heart service they would recommend for your child in fifteen years, because the answer tells you whether they are thinking that far ahead.

After open surgery you will be told not to lift your child under the arms for roughly six to eight weeks while the breastbone knits, and to lift from the bottom instead. Practise it before the operation.

13. Choosing a Unit in the Region

For this operation the unit matters more than any individual name. Weigh these:

• Annual Fontan completions performed, and how many Fontan patients are currently followed

• Whether they carried out your child's earlier stages, or are taking on a child operated elsewhere

• Whether the intensive care is paediatric and cardiac, with overnight intensivist cover

• Availability of extracorporeal support

• Whether the catheter laboratory can close a fenestration later

• Access to a joint cardiology and surgery meeting

• Long-term liver and rhythm monitoring arrangements

• Whether they will review scans and results sent from your home country

• Whether they discuss the long arc openly, including transplant in adulthood

Years of experience alone tells you little here, and a long adult cardiac career tells you almost nothing.

14. Questions to Ask Before You Consent

Ask for written answers, particularly if you are travelling.

• What were my child's pressure and resistance measurements, and are they inside your acceptable range?

• Will you repeat the catheterisation here, and does the estimate include it?

• Extracardiac conduit or lateral tunnel, and why that one for my child?

• Do you plan a fenestration, and what is the plan for closing it?

• How many days of intensive care and how long in hospital do you expect?

• How likely is prolonged chest drainage, and what happens if it persists?

• How many weeks in the region before you would clear my child to fly?

• What oxygen saturation should I call you about, and what is the out-of-hours number?

• What will the blood-thinning plan be, and how is it monitored from abroad?

• What diet restrictions go home with us?

• What does the realistic long-term picture look like for my child?

• At what point would transplant be discussed?

• Will you review scans and results we send from home, and how often?

• What happens, and who pays, if a complication develops while we are still in India?

15. Travelling With a Child From Abroad

Families come to the region for this operation from the Middle East, Central Asia, South Asia and Africa. Given the length of stay, visa and accommodation planning matters more here than for shorter procedures.

Country guides covering flights, visa documents and costs:

• Planning the trip from Iraq

• Planning the trip from Oman

• Planning the trip from Bangladesh

• Planning the trip from Turkmenistan

• Planning the trip from Tanzania

• Planning the trip from Kenya

• Planning the trip from Zambia

• Planning the trip from Zimbabwe

• Planning the trip from Ghana

• Planning the trip from South Sudan

Interpreters in Arabic, Bengali, Russian, French and Kiswahili are available at most of the hospitals listed here, and should be booked before you arrive rather than requested on the day.

16. Looking Wider

For children's heart conditions generally, including the earlier stages that precede a Fontan and the other congenital defects treated in India, see children's heart care in India.

For the surgical pathway across other defects, children's heart surgery more broadly covers what an operation involves.
