Tetralogy of Fallot surgery in Turkey: what the condition is
Tetralogy of Fallot (TOF) is a congenital heart condition, present from birth, in which four related defects reduce the amount of oxygen-rich blood reaching the body. A hole between the lower chambers (ventricular septal defect), a narrowing at or below the pulmonary valve that restricts blood flow to the lungs, an aorta that sits over the hole instead of the left ventricle, and a thickened right ventricle together mix oxygen-poor blood into the circulation. Babies may look blue (cyanosis), tire during feeds or have sudden "tet spells" of deep blueness. Tetralogy of Fallot surgery closes the hole and widens the outflow to the lungs so that blood flows the right way.
This guide is written for parents and for adults with unrepaired or earlier-repaired TOF. It explains what the operation involves, when it is done, what the outlook is, how a later valve operation fits in, the approximate cost in Turkey against the UK, US and Germany, and how to choose a congenital heart centre. For related care see our overview of cardiology and heart surgery in Turkey.
How is tetralogy of Fallot diagnosed?
Many cases are suspected on the pregnancy scan or after birth when a heart murmur or low oxygen saturation is noticed. The diagnosis is confirmed by an echocardiogram (heart ultrasound; see our page on echocardiography), which shows the hole, the narrowing and the position of the aorta. Further tests include a chest X-ray, ECG, pulse oximetry, and sometimes cardiac MRI, CT or cardiac catheterisation to map the pulmonary arteries and the coronary arteries before surgery. Doctors look for associated conditions such as a right-sided aortic arch, additional holes, or genetic syndromes like 22q11 deletion, because they affect the plan. Doctors at specialist centres decide the timing from these findings.
When is tetralogy of Fallot surgery done?
Complete repair is usually planned in the first year of life, commonly between 3 and 12 months, and sooner for babies whose oxygen levels are low or who have spells. This timing is described in guidance from the American Heart Association and the European Society of Cardiology. Some infants who are very small, premature or have poorly developed pulmonary arteries first have a palliative operation, such as a Blalock-Taussig shunt or stenting of the outflow tract, to improve blood flow to the lungs until complete repair is safe. Older children and adults who were never operated on can also have repair, though results depend on how much the right ventricle and lungs have been affected over the years.
Adults who had repair in childhood often need lifelong follow-up and sometimes a second operation; this is covered below.
What happens during complete repair, step by step?
The operation is done through the breastbone under general anaesthesia and takes about three to six hours. The heart is stopped and the heart-lung machine takes over circulation. The surgeon closes the ventricular septal defect with a patch, so that the left ventricle connects only to the aorta. The obstruction to the lungs is relieved by cutting away thickened muscle below the valve and, if needed, opening or widening the pulmonary valve and the main pulmonary artery, sometimes with a patch across the valve ring (a transannular patch). Where possible the surgeon preserves the pulmonary valve. Any extra holes are closed, the heart is restarted and the chest is closed with temporary drains.
These steps are the standard principles; the exact technique depends on the child's anatomy. For similar procedures see our pages on congenital heart surgery and ventricular septal defect surgery.
Which operation suits which situation: shunt, complete repair or valve replacement?
| Operation | Best suited to | Typical limits |
|---|---|---|
| Palliative shunt or outflow stent | Very small or fragile babies, poorly developed pulmonary arteries | Temporary; complete repair is still needed later |
| Complete repair | Most infants and children; adults with unrepaired TOF | Pulmonary regurgitation or residual narrowing may develop over years |
| Pulmonary valve replacement (later) | Children and adults with a leaking valve and an enlarged right ventricle after repair | Valves wear out; replacement may need repeating |
Pulmonary valve replacement can be done by open surgery or, in selected patients, by a catheter-delivered valve. The related page on heart valve replacement explains the general principles of valve surgery.
What is the outlook after tetralogy of Fallot repair?
The outlook is good. Large studies and bodies such as the British Heart Foundation report that most children who have complete repair in a specialist centre survive into adulthood and lead active lives. However, repair is not always a cure. Over years the pulmonary valve may leak (pulmonary regurgitation), the right ventricle may enlarge, abnormal heart rhythms can occur, and some people need a valve replacement in their teens, twenties or later. This is why lifelong follow-up with a congenital heart specialist is advised, including regular echocardiograms, ECGs and sometimes MRI scans. A trustworthy centre will explain these long-term issues rather than present repair as a final cure.
Tetralogy of Fallot surgery cost in Turkey compared with the UK, US and Germany
The figures below are approximate ranges for complete repair including the hospital stay, not hospital quotes. Most families in the UK and Germany receive care through public systems; the figures show private or self-pay prices. Cost depends on the child's age and weight, complexity (such as a transannular patch or an extra procedure), the length of intensive care, the type of valve if replaced, and any complications. Each hospital confirms its own price in writing.
| Country | Approximate cost range |
|---|---|
| Turkey | €9,000 – €28,000 |
| United Kingdom | €30,000 – €75,000 |
| United States | €60,000 – €200,000 |
| Germany | €30,000 – €70,000 |
A package should list the pre-operative tests, the surgeon, anaesthetist and perfusion team, intensive care and ward days, medication, follow-up checks, and what happens if a longer stay or a second procedure is needed. Ask who pays for complications, and whether accommodation for a parent is included.
Intensive care, hospital stay and recovery after the operation
After surgery the child goes to intensive care, usually for one to three days, with a breathing tube removed within the first day in many cases. Drains and pacing wires come out over the next days. A typical hospital stay is about 7 to 10 days. Babies may need diuretics and feeding support. Parents are shown how to care for the wound, how to hold their child, and which warning signs need urgent attention, such as fever, breathlessness, pale or blue lips, wound redness or reduced feeding. Most children are back to normal play within four to six weeks, and the breastbone heals fully in about six to twelve weeks, during which heavy lifting and contact play are avoided. Adults usually return to desk work after four to eight weeks.
Risks and complications of tetralogy of Fallot surgery
The risk of death from complete repair in an experienced centre is low, in modern series generally a few percent or less, and higher in very small babies, those with other conditions or when the anatomy is complex. Early complications include bleeding, infection, fluid around the lungs or heart, abnormal heart rhythm and temporary kidney or lung problems. Later risks include a leaking pulmonary valve, residual narrowing, a small leftover hole, heart rhythm disorders and the need for further surgery or catheter procedures. Because the risks rise with the child's complexity, the surgeon should give an individual estimate after reviewing the scans; treat any clinic that promises a risk-free result with caution.
How many days to stay in Turkey and travelling with a child
Plan on about three to four weeks in total: a few days for assessment and scans, the operation, the hospital stay and a check before flying. The surgeon decides when the child is fit to fly, often around two to three weeks after surgery, depending on oxygen levels, wound healing and drain removal. Bring all previous records, echo reports and discs, any medication list and immunisation records. Arrange a local paediatric cardiologist at home so that follow-up scans and medication are not interrupted, and ask the hospital to send a written discharge summary.
How to choose a congenital heart centre and questions to ask
Choose a centre with a dedicated paediatric cardiac surgery team, a paediatric cardiac intensive care unit, anaesthetists who treat infants, and a surgeon who performs congenital repairs regularly. Ask about the number of TOF repairs done each year and the centre's published outcomes. Red flags include a quote given without reviewing the echo reports, guaranteed outcomes, no named surgeon, no paediatric intensive care and pressure to pay quickly.

Frequently asked questions
It is a congenital heart condition with four defects: a hole between the lower chambers, a narrowing to the lungs, an aorta positioned over the hole and a thickened right ventricle. Together they reduce oxygen in the blood.
Complete repair is usually planned in the first year, often between 3 and 12 months, sooner if oxygen levels are low or the baby has spells. Very small babies may first have a palliative shunt.
Approximate ranges are €9,000 to €28,000 in Turkey against about €30,000 to €75,000 in the UK for private care. The price depends on age, complexity and intensive care days, and the hospital confirms it in writing.
The operation usually takes three to six hours under general anaesthesia with a heart-lung machine, followed by one to three days in intensive care.
A hospital stay of about 7 to 10 days is typical. Most children return to normal play within four to six weeks, while the breastbone takes about six to twelve weeks to heal.
Repair gives most children an active life, but it is not always final. The pulmonary valve may leak over time, so lifelong follow-up and sometimes valve replacement are needed.
Yes. Adults with unrepaired TOF can have repair, and adults who were repaired as children may need pulmonary valve replacement. Results depend on how the heart has adapted.
Risks include bleeding, infection, rhythm problems and the need for later procedures. The risk of death is low in experienced centres but depends on the child's anatomy and other conditions.
Some do, most often a pulmonary valve replacement in the teens or adulthood. A congenital heart specialist monitors the valve and right ventricle with regular scans.
Plan on about three to four weeks, covering tests, surgery, hospital stay and the surgeon's clearance to fly, which is often two to three weeks after the operation.
