Pediatric aortic valve replacement: what it is and when a child needs it
Pediatric aortic valve replacement is open-heart surgery in which a child's diseased aortic valve, the one-way door between the left ventricle and the aorta, is replaced with a new valve. The valve is usually damaged from birth (a bicuspid or single-leaflet valve, or a narrowed valve), or has been harmed by earlier treatment or by rheumatic fever. It is a major operation and is normally considered only after repair, balloon dilatation or a valve-sparing option has been judged unsuitable or has failed. Hospitals in Turkey with a dedicated paediatric cardiac surgery unit treat children from many countries, and families often ask for a second opinion before travelling.
This guide explains how the decision is made, which valve types are used in growing children, what is known about long-term results, what the surgery costs in Turkey compared with the UK, US and Germany, and how a stay is organised. It is general information, not advice for an individual child; the treating paediatric cardiologist and surgeon decide the plan from your child's scans. For the wider field see our cardiology treatments in Turkey.
What problems of the aortic valve lead to replacement in a child?
Two faults matter. In stenosis the valve opens poorly, so the left ventricle works against a tight outlet and its muscle thickens. In regurgitation the valve leaks, so blood falls back into the ventricle and the chamber enlarges. Many children have a mixture of both. Common causes are a bicuspid valve, a valve narrowed from birth, damage after infective endocarditis, rheumatic heart disease, or wear after an earlier balloon or repair procedure. Doctors follow the child with echocardiography and sometimes MRI or catheter studies, and look at symptoms (breathlessness, tiring, fainting, chest pain), the size and function of the left ventricle and the width of the aortic root.
Surgery is usually advised when there are symptoms, when the ventricle is enlarging or its function is falling, or when pressure across the valve is severe. A child with a mild fault may be watched for years without an operation.
Repair, balloon valvotomy or replacement: which comes first?
Replacement is rarely the first step in a child, because every artificial valve has costs of its own. Balloon valvuloplasty at catheterisation can open a narrowed valve in the very young and may delay surgery. Surgical repair (opening fused leaflets, reshaping or extending a leaflet) keeps the child's own valve and avoids lifelong blood thinners. Replacement is chosen when the valve cannot be repaired well enough to last. The comparison below is general; individual anatomy decides.
| Option | Best suited to | Typical limits |
|---|---|---|
| Balloon valvuloplasty | Narrowed valve in newborns and infants | Can leave or cause leakage; often temporary |
| Valve repair | Valve with usable leaflets | May need re-operation as the child grows |
| Replacement (mechanical, biological or Ross) | Valve that cannot be repaired | Each valve type has its own trade-offs, see below |
The adult operation is described in our guide to replacement of the aortic valve; children differ because the heart and the aortic root keep growing.
Which valve is used in children: mechanical, biological or the Ross procedure?
There is no perfect valve for a child, and this choice is the heart of the consultation.
- Mechanical valve. Made of carbon and metal and very durable, but it needs lifelong warfarin, regular INR blood tests and care around sports and pregnancy later in life. It does not grow.
- Biological (tissue) valve. Made from animal tissue; no long-term warfarin is needed, but in children it tends to wear and calcify faster than in adults, so further operations are expected.
- Ross procedure. The child's own pulmonary valve is moved into the aortic position and a donor (homograft) valve replaces the pulmonary valve. The new aortic valve is the child's own living tissue and can grow, and no warfarin is needed. It is a technically demanding, two-valve operation performed by experienced centres, and the pulmonary side and the aortic root may need further treatment later.
The surgeon should explain which options are feasible for your child's valve and root, and give a realistic picture of the re-operations to expect.
Does pediatric aortic valve replacement work, and how long does it last?
Valve surgery in children is well established, and most children who need it recover well and gain normal activity. What is honestly uncertain is how long a particular valve will last. Studies of mechanical valves show durability, balanced against bleeding and clotting risks linked to anticoagulation. Biological valves are more likely to need replacing within years in young patients. The Ross procedure has good long-term outcomes in specialist centres but is not suitable for every anatomy. Because of this, children with a replaced valve need lifelong follow-up with a congenital cardiologist, and most should expect at least one further procedure as they grow. Be cautious of any promise that one operation will be the last.
How much does pediatric aortic valve replacement cost in Turkey?
The figures below are approximate ranges for the operation and the hospital stay, not hospital quotes. Children's cases vary widely with the child's age, the valve chosen, whether the Ross procedure is used, and the time spent in intensive care.
| Country | Approximate cost range |
|---|---|
| Turkey | €12,000 – €35,000 |
| United Kingdom | €30,000 – €80,000 (private) |
| United States | €60,000 – €200,000 |
| Germany | €30,000 – €70,000 |
What changes the price: the valve type (a homograft or a Ross operation costs more than a standard prosthesis), the surgical team and theatre time, days in intensive care and on the ward, pre-operative imaging, and complications that extend the stay. A package should state what is included: the operation, anaesthesia, intensive care, tests, medication, one accompanying parent's accommodation and transfers. Ask for what is not included, such as treatment of complications, in writing.
What happens during the operation, step by step?
Surgery is under general anaesthesia and takes roughly three to six hours. The surgeon opens the breastbone, connects the child to a heart-lung machine, cools or arrests the heart as needed and opens the aorta. The diseased valve is removed and the new valve is sewn in, or, in a Ross operation, the pulmonary valve is transferred and the pulmonary side rebuilt with a homograft. The aorta is closed, the heart restarted and the breastbone wired together. The child goes to intensive care, usually on a ventilator for the first hours, with drains and monitoring lines. Parents can ask who will be on call overnight and how often they will be updated.
How long is the hospital stay and recovery after pediatric aortic valve replacement?
Children usually spend one to three days in intensive care and a total of seven to ten days in hospital if recovery is smooth. Families should plan to remain in Turkey for about two to three weeks, so that the heart team can check the echocardiogram, wound and medication before a flight. Younger children often recover faster than adults. At home the main milestones are as follows.
- Weeks 1 to 2: wound care, regular pain relief, walking, no lifting.
- Weeks 4 to 6: the breastbone is knitting; school or nursery often resumes after about four to six weeks.
- About 6 to 12 weeks: contact sports, gym and rough play usually remain restricted until the surgeon agrees.
Children with a mechanical valve begin warfarin and need INR testing locally, so agree before travelling who will manage it at home.
What are the risks of pediatric aortic valve replacement?
All open-heart surgery has risks, and a paediatric surgeon should discuss them openly. They include bleeding, infection, rhythm disturbances (a few children need a pacemaker), stroke, kidney or lung problems and, rarely, death. Specific to valves are clots on a mechanical valve, bleeding on warfarin, valve leakage or narrowing over time, and endocarditis, which is why dental care and antibiotic advice matter for life. The NHS and the British Heart Foundation publish plain-language guidance on valve surgery, and the American Heart Association has guidance on endocarditis prevention; use them to prepare questions. Ask the team for its own figures for children of your child's age and size rather than relying on general statistics.
Who is a suitable candidate for treatment in Turkey, and who is not?
A child whose valve disease has been fully assessed, who is stable enough to travel and whose family can stay for the recovery period is a candidate for a hospital review. A child who is critically ill, on high-dose intravenous medication, or very unstable may be safer treated near home or transferred in a medical flight arranged by clinicians. Neonates and complex congenital heart disease should only be operated on in centres with specific paediatric cardiac surgery, intensive care and anaesthesia teams. For related heart conditions see our guides to heart valve replacement and congenital heart surgery.
How to choose a paediatric heart team, and what to ask
Check that the operation is performed by a surgeon trained in congenital and paediatric cardiac surgery, in a hospital with a paediatric intensive care unit, a paediatric cardiac anaesthetist and a perfusionist, and that you get a written plan and price before any deposit. Red flags: no named surgeon, quotes with no breakdown, no review of your child's records first, guaranteed outcomes and pressure to decide quickly. Read how our process works and send the scans and reports through the free quote page so a team can review them first. Questions to ask:
- Which valve do you recommend for my child, and why not the others?
- How many children with this operation does the team treat each year?
- Can the Ross procedure be done here, and is my child suited to it?
- Who looks after my child in intensive care, day and night?
- What follow-up and anticoagulation plan will my local doctors need?
- What is not included in the quoted price?

Frequently asked questions
It is open-heart surgery in which a child's diseased aortic valve is replaced with a mechanical valve, a tissue valve or, in selected cases, the child's own pulmonary valve (Ross procedure). It is used when repair or balloon treatment is unsuitable.
Usually when the valve is severely narrowed or leaking and cannot be repaired, particularly with symptoms, an enlarging left ventricle or falling heart function. Mild disease is often watched for years.
Approximate range is €12,000 to €35,000 in Turkey, against about €30,000 to €80,000 privately in the UK. The final price depends on the valve type, the child's age and the days in intensive care, and is confirmed in a written quote.
There is no single answer. Mechanical valves last but need warfarin, tissue valves avoid warfarin but wear sooner, and the Ross procedure uses living tissue but is a larger operation. The surgeon matches the choice to your child's anatomy.
Hospital stay is usually seven to ten days if all goes well. Many children return to school after four to six weeks, while contact sports stay restricted for around three months until the surgeon agrees.
Often yes at some point. Children outgrow valves, and tissue valves wear faster in young patients. Lifelong follow-up with a congenital cardiologist is part of the plan, so ask the team what to expect.
A mechanical valve needs lifelong warfarin with regular INR tests. Tissue valves and the Ross procedure usually avoid long-term anticoagulation, though aspirin or short-term treatment may be used.
It is a major operation with real risks, including bleeding, infection, rhythm problems and stroke. Risk depends on age, heart function and the team's experience, so ask for the team's own results in children.
Plan for about two to three weeks: roughly a week in hospital and further days for checks of the echocardiogram, wound and medication before flying home. Your surgeon gives the final advice.
Yes, and for critically ill children it may be safer. Many families seek a second opinion first. Ask for an opinion on the scans before deciding to travel.
