Pediatric Cardiac Surgery

Pediatric Cardiac Surgery for Children with Heart Conditions

Pediatric cardiac surgery is an operation on the heart, heart valves, major blood vessels or the structures around the heart in a baby, child or adolescent. It is most often performed to repair congenital heart disease — a heart difference that developed before birth — and, less often, to treat heart problems acquired during childhood through infection, inflammation or disease of the heart muscle or valves. It is intended for children whose circulation cannot be managed safely with observation, medication or catheter treatment alone.

Learning that your child may need heart surgery is difficult. The questions arrive quickly. How serious is the condition? Is an operation genuinely necessary, or can it wait? What happens in theatre, and what will recovery look like? If you are weighing up treatment abroad, practical worries add themselves to the list: distance, language, and being far from home at a demanding time. This page answers those questions as directly as the subject allows.

Most parents begin online. Searches for Presbyterian pediatric cardiology, for university children’s hospitals and for individual surgeons’ names are often the first step towards understanding what children’s heart care involves and who provides it. Named programmes are a reasonable starting point, but the decisions that matter — whether to operate, when, and how — rest on your child’s specific anatomy, not on a hospital’s name. Whether your research started with Presbyterian pediatric cardiology in the United States or a children’s heart centre closer to home, the medical questions you need answered are the same, and they are the questions this page works through.

No two children with the same diagnosis follow identical paths. Growth pattern, symptoms, oxygen levels, other health conditions and family circumstances all shape the plan. That is why decisions about surgery are made by a team rather than a single doctor: pediatric cardiologists, pediatric cardiac surgeons, cardiac anaesthetists, intensive care specialists, imaging experts, nurses and rehabilitation professionals. The goal is not simply to correct an anatomical problem. It is to support healthy circulation, protect heart and lung function, promote normal development and help each child move forward with the best possible quality of life.

At Acibadem, pediatric cardiac surgery sits within a coordinated children’s heart programme. Families are supported through diagnostic evaluation, treatment discussions, the operation itself, intensive care, discharge planning and long-term follow-up, with care coordination and interpretation available for families arriving from abroad.

What Is Pediatric Cardiac Surgery?

Pediatric cardiac surgery is surgery on the heart, heart valves, major blood vessels or structures surrounding the heart in babies, children and teenagers. Its most common purpose is repairing congenital heart disease, which ranges from small openings between heart chambers that may close naturally to complex conditions involving multiple areas of the heart and circulation. Some children need treatment soon after birth; others can be monitored for years before an operation becomes the safest option.

Depending on the diagnosis, surgery may close an opening in the heart, repair or replace a valve, widen a narrowed blood vessel, reconstruct part of the aorta or pulmonary arteries, improve blood flow to the lungs, or correct the connections between the heart chambers and the major vessels. In some complex conditions, treatment is delivered in carefully timed stages as the child grows. In others, a single operation can provide a durable repair.

The word “repair” matters here. Congenital heart surgery is usually reconstructive: the surgeon works with the child’s own tissue wherever possible, choosing patches, sutures or conduits with attention to durability, compatibility and — critically in children — future growth. An adult heart operation fixes a heart that has finished growing. A child’s repair has to keep working as the heart doubles and triples in size.

Is pediatric cardiac surgery always open-heart surgery?

No. Many operations are open-heart procedures using a heart-lung machine, also called cardiopulmonary bypass. This system temporarily takes over the work of the heart and lungs, allowing the surgeon to operate precisely within or around a still, bloodless heart. But certain procedures — for example, some operations on the aorta or on vessels outside the heart itself — can be completed without bypass. The technique is selected according to the condition and the safest route to repair, not according to a standard formula.

When is a catheter procedure used instead of an operation?

Some heart defects can be treated through blood vessels, using thin tubes guided to the heart under imaging — closing certain openings with a device, or widening a narrowed valve or vessel with a balloon or stent. Other children need medication and observation only. Others still need a combined approach, in which catheter intervention and surgery are used at different stages of care, sometimes in coordinated “hybrid” procedures. The heart team determines the most appropriate pathway after reviewing the child’s anatomy, symptoms, age, weight, overall health and expected development. If your child has been offered surgery, it is entirely reasonable to ask why a catheter approach is not suitable; a good team will explain the reasoning plainly.

Who Is a Pediatric Cardiologist — and Who Operates?

Parents meet two different specialists on this journey, and the distinction is worth understanding, because each answers different questions.

Who is a pediatric cardiologist?

A pediatric cardiologist is a children’s doctor who specialises in diagnosing and managing heart conditions in fetuses, infants, children and adolescents — without operating. Cardiologists perform and interpret echocardiograms, monitor heart rhythm and function, manage medication, carry out catheter procedures where appropriate, and decide with the surgical team whether and when an operation is needed. Your child’s relationship with pediatric cardiology usually begins before any surgery and continues for years afterwards; the cardiologist is the constant figure in long-term congenital heart care.

What does a pediatric heart surgeon do?

A pediatric heart surgeon performs the operation itself: opening the chest, establishing bypass where needed, and repairing or reconstructing the heart and vessels. Surgeons in this field concentrate on congenital and childhood heart disease specifically, because operating on a newborn’s heart — which can be the size of a walnut — demands different techniques, judgement and instruments from adult cardiac surgery. The surgeon leads the operative plan, but works within the wider team throughout diagnosis, theatre and intensive care.

How do you become a pediatric cardiac surgeon?

The pathway is long and deliberately so. It typically begins with a medical degree, followed by residency training in surgery and then specialist training in cardiothoracic surgery. Only after that does a surgeon undertake dedicated training in congenital heart surgery, learning the specific repairs, staged strategies and newborn techniques the field requires. In total, most pediatric heart surgeons train for well over a decade after entering medical school before operating independently on children, and even then they continue building experience across the enormous variety of congenital anatomy.

How long is a pediatric cardiac surgery fellowship?

In most systems, the dedicated congenital cardiac surgery fellowship comes after completed cardiothoracic training and typically lasts a further year or more; many surgeons extend their congenital training or complete additional fellowships abroad. Exact structures vary by country — the titles and stages differ between the United States, the United Kingdom and elsewhere — but the destination is the same: a surgeon whose entire operative practice is the childhood heart. For parents, the practical takeaway is simple: ask any prospective surgeon about their congenital training and their ongoing experience with your child’s specific condition.

Who May Need Pediatric Cardiac Surgery?

A child may be referred for surgical evaluation after a heart condition is identified during pregnancy, soon after birth, during a routine childhood examination, or later in adolescence. Some heart differences are found because a clinician hears a heart murmur. Others become apparent when a baby struggles to feed or gain weight, when a child tires more easily than expected, or when there are signs that the heart or lungs are under strain.

Symptoms vary significantly with the type and severity of the condition. In newborns and infants, possible signs include rapid breathing, sweating or tiring during feeds, poor weight gain, bluish or greyish lips and skin, unusual sleepiness, or recurrent chest infections. In older children and adolescents, symptoms may include shortness of breath with activity, reduced exercise tolerance, chest discomfort, palpitations, fainting, dizziness, fatigue, swelling or repeated respiratory infections. And some children feel entirely well despite a significant structural problem found on imaging — feeling fine is not, on its own, evidence that surgery is unnecessary.

How is a child’s heart condition diagnosed?

Diagnosis begins with a careful clinical evaluation: medical history, development, growth and family history. Testing may then include echocardiography (ultrasound of the heart, the workhorse of pediatric cardiology), electrocardiography, chest imaging, cardiac magnetic resonance imaging, computed tomography, pulse oxygen measurement, exercise testing for appropriate age groups and laboratory studies. In selected cases, cardiac catheterisation is used to measure pressures and oxygen levels inside the heart and vessels, or to clarify complex anatomy that non-invasive imaging cannot fully resolve. The purpose of all of this is precision: a surgical plan is only as good as the anatomical picture behind it.

Can heart problems be found before birth?

Yes. For unborn babies with a suspected heart difference, fetal echocardiography can provide valuable information before delivery. This allows the family and the clinical team to plan the birth in an appropriate setting and to prepare any specialised support the newborn may need in the first hours and days of life.

A recommendation for surgery is generally made when the defect affects circulation, increases pressure or volume load on the heart, causes symptoms, limits growth or activity, lowers oxygen levels, creates a risk of damage to the lungs or heart muscle, or is unlikely to improve without intervention. Timing is individualised. Acting too early and waiting too long both carry risks, and weighing them requires experienced judgement rather than a rule of thumb.

Conditions Treated with Congenital Heart Disease Surgery

Congenital heart disease surgery covers a broad range of structural conditions, and the exact operation depends on the child’s anatomy and how the heart is functioning. Common indications include defects of the walls separating the heart chambers, valve abnormalities, narrowing of major blood vessels, and complex conditions affecting how blood flows through the heart and lungs. You can read more about the underlying diagnoses on our congenital heart diseases page.

• Atrial septal defect: an opening between the upper heart chambers that may cause increased blood flow to the lungs and enlargement of the right side of the heart.
• Ventricular septal defect: an opening between the lower pumping chambers. Small defects may close on their own; larger defects can lead to fast breathing, poor growth or pressure changes in the lungs.
• Atrioventricular septal defect: a more complex defect involving the central portion of the heart and its valves, sometimes associated with genetic conditions such as Down syndrome.
• Tetralogy of Fallot: a combination of heart differences that restricts blood flow to the lungs and can lower oxygen levels, sometimes causing cyanosis.
• Transposition of the great arteries: a serious newborn condition in which the major arteries arise from the wrong pumping chambers, usually requiring early specialised treatment.
• Coarctation of the aorta: narrowing of part of the body’s main artery, which may affect blood flow to the lower body and strain the heart.
• Aortic arch abnormalities: interruption, narrowing or unusual formation of the aortic arch and its branches.
• Valve disorders: narrowing or leakage of the pulmonary, aortic, mitral or tricuspid valve that may require repair, reconstruction or, less commonly, replacement. The principles overlap with heart valve disease treatment more broadly, but valve surgery in a growing child raises its own questions about durability and future procedures.
• Single-ventricle conditions: complex disorders in which one pumping chamber is underdeveloped or unable to support circulation effectively. These often require staged treatment across the first years of life.
• Anomalous pulmonary venous return: abnormal connections of the veins returning blood from the lungs to the heart.
• Patent ductus arteriosus: persistence of a fetal blood vessel connection after birth, when medication or catheter treatment is not suitable or has not resolved the problem.
• Acquired heart conditions: selected cases of infective endocarditis, rheumatic valve disease, cardiac tumours, complications of previous procedures, or other conditions requiring surgical treatment.

Children who have already undergone heart surgery may need a later procedure as they grow, or if a repaired area, valve, conduit or vessel requires further attention. This is expected in some conditions rather than a sign of failure, and it is why long-term follow-up runs through congenital heart care — including into adolescence and adulthood where appropriate.

How Pediatric Cardiac Surgery Is Performed

Detailed evaluation and surgical planning

Before surgery, the team confirms the diagnosis and reviews the child’s current condition. Imaging is examined closely to define the anatomy of the heart, valves and vessels. For complex cases, the information may be reviewed at a multidisciplinary cardiac board, where pediatric cardiologists, surgeons, imaging specialists, anaesthetists and intensive care physicians discuss the safest and most appropriate strategy together.

Families receive an explanation of why surgery is recommended, the expected benefits, possible alternatives, the anticipated hospital course and the important risks specific to their child. Preoperative assessment also includes blood tests, infection screening, medication review by the treating team, anaesthesia evaluation and guidance about fasting. Parents are encouraged to share information about allergies, previous procedures, current medications, feeding concerns, developmental needs and any family history of bleeding or anaesthesia complications — details that genuinely change how the team prepares.

The day of surgery

On the day of the operation, the child is cared for by a pediatric anaesthesia team experienced in age-specific monitoring, medication dosing, temperature management and pain control. General anaesthesia is used, so the child is asleep throughout and unaware of the operation. Monitoring lines are placed to measure blood pressure, oxygen levels, heart rhythm, temperature and other vital parameters continuously.

The surgical approach depends on the condition. Many operations are performed through an incision in the centre of the chest, giving the surgeon direct access to the heart. In carefully selected patients, smaller-incision approaches may be considered. The choice is based on safety, the anatomy that needs repairing, the child’s size, and the need for long-term access to the heart if future procedures are possible — a consideration that matters more in children than in adults.

During open-heart procedures, cardiopulmonary bypass maintains circulation while the heart is repaired. The surgeon may close a defect with sutures or a patch, reshape a valve, relieve an obstruction, reconnect blood vessels, enlarge a narrowed area or reconstruct complex heart structures. Some operations are intended as definitive repairs. Others are palliative or staged procedures that improve circulation and create the best conditions for a later operation. In complex congenital heart disease, the planned pathway can evolve as the child grows and as follow-up imaging adds information; a good team will tell you this at the outset rather than presenting the first operation as the whole story.

Technology that supports precise care

Pediatric cardiac surgery relies on a system of technologies rather than a single device. High-resolution echocardiography and cross-sectional imaging help the team understand the heart in detail before surgery. Intraoperative imaging can assess the repair before the child leaves the operating theatre. Continuous monitoring in theatre and in the pediatric cardiac intensive care unit lets clinicians respond promptly to changes in heart function, circulation, oxygenation, temperature and fluid balance. For selected complex cases, three-dimensional image processing and surgical planning tools help the team visualise unusual anatomy, and catheterisation capability matters because some children benefit from catheter treatment before or after surgery, or from coordinated hybrid strategies. Technology supports decision-making; experienced clinical interpretation remains central to safe care.

How long does pediatric heart surgery take?

Pediatric heart surgery usually takes several hours from anaesthesia to completion for a relatively straightforward repair, and complex reconstruction can take considerably longer. Bear in mind that operating-room time includes anaesthesia preparation, positioning, line placement, the procedure itself and careful stabilisation before transfer to intensive care — so the hours you spend waiting are longer than the repair itself, and that is normal.

Early recovery in intensive care

After surgery, children are usually cared for in a dedicated pediatric cardiac intensive care unit. Some remain on a breathing machine for a period, particularly after major operations or in very young infants. Medications can support the heart, blood pressure, comfort and fluid balance while recovery begins. Chest tubes may temporarily drain fluid, and temporary pacing wires may support heart rhythm in some cases if needed. The team monitors pain, feeding, urine output, heart rhythm, oxygen levels, wound healing and signs of infection, and keeps parents informed as the child progresses from intensive care to a pediatric inpatient room. Length of stay depends on the complexity of the operation, the child’s age and preoperative health, feeding progress, and whether any postoperative issues need additional treatment.

Why Timing Matters

Some heart conditions require urgent treatment in the newborn period because the circulation depends on a temporary fetal blood vessel that naturally closes after birth. Other conditions can be safely monitored for months or years, allowing a baby to grow before surgery. The key point is not that every diagnosis needs immediate surgery — it is that every child deserves timely evaluation by an experienced heart team, so the window for the safest treatment is not missed.

When a significant defect is left untreated beyond the appropriate time, the heart works harder to compensate. Increased blood flow or pressure in the lungs can eventually cause changes that are more difficult to reverse. A child may struggle with feeding, growth, activity or repeated respiratory illness. Low oxygen levels can affect energy and development, while abnormal rhythms, valve dysfunction, chamber enlargement or reduced heart function may become more likely in certain conditions.

Timely treatment can protect the lungs and heart muscle, support weight gain and physical development, reduce the burden of symptoms, and in some circumstances make future treatment more straightforward. But timing must always be individualised — and families should not read monitoring as inaction. Careful observation, with scheduled imaging and review, is an active, evidence-based part of treatment when surgery is not yet indicated.

Benefits of Pediatric Cardiac Surgery

The potential benefits depend on the diagnosis and the type of repair, but treatment is generally intended to improve circulation, relieve strain on the heart and support the child’s growth and daily life.

Benefit	What It Means for You
Improved blood flow and oxygen delivery	Repairing the heart’s structure can help blood move through the heart and lungs more effectively, reducing cyanosis or circulation-related symptoms where present.
Reduced workload on the heart	Closing significant defects or relieving narrowed areas may reduce excess pressure or volume strain that could otherwise affect heart function over time.
Better feeding, growth and energy	Infants and children who have been using extra energy to breathe or feed may gradually gain weight and tolerate activity more comfortably after recovery.
Protection of lung health	Timely correction of certain defects can reduce the risk of long-term pressure-related changes in the blood vessels of the lungs.
Improved participation in childhood activities	Many children are able to return to school, play, family routines and age-appropriate physical activity with guidance from their cardiology team.
A clearer plan for future care	For complex congenital heart disease, surgery can establish the next stage of a structured long-term pathway, including surveillance as the child grows.

Pediatric Cardiac Surgery Recovery Timeline

Recovery differs for every child, and especially between newborns, infants, school-age children and adolescents. The following timeline is a general guide, not a fixed schedule — your child’s team will tell you where their progress sits against it.

Time Period	What Patients Can Expect
Day 1	Care is usually provided in the pediatric cardiac intensive care unit. The child is closely monitored for heart rhythm, breathing, circulation, pain, bleeding and fluid balance. Some children remain sedated and on breathing support initially.
First Week	Breathing support, drains and monitoring lines are removed as the child stabilises. Feeding, movement, comfort and sleep become important milestones. Transfer from intensive care to the inpatient unit often occurs during this period when clinically appropriate.
First Month	Most children continue healing at home, with follow-up visits to assess the incision, heart function, medications, feeding or appetite, and activity progression. Tiredness and changes in routine are common during early recovery.
First Three Months	Energy levels and participation in daily activities typically continue to improve. The cardiology team may adjust medications and advise when school, sports, swimming, travel or more strenuous activity can resume.
Longer Term	Ongoing cardiology follow-up remains important, even after a successful repair. Some children need periodic imaging, rhythm monitoring, medication review, activity guidance or future procedures as their heart and body grow.

Where the breastbone has been divided, it heals in the way any bone heals — gradually, over weeks. The team will give age-appropriate guidance on lifting, carrying and play during this period, particularly for infants who are picked up many times a day.

What Influences Outcomes and a Good Result?

Pediatric cardiac surgery has advanced significantly, and many children do very well after treatment. But outcomes are best discussed in the context of the individual diagnosis, not a single general statistic. The expected course differs widely between a child having a straightforward isolated defect repaired and a newborn with a complex, multi-stage heart condition — which is why this page deliberately avoids quoting one headline figure for all of it.

Important factors include the specific heart anatomy, the severity of the condition, the child’s age and size at surgery, heart and lung function, oxygen levels, nutritional status, the presence of genetic or developmental conditions, previous operations, and any other medical concerns. Urgency also matters: a planned operation in a stable child may have a different recovery profile from emergency surgery in a critically ill newborn.

The experience and coordination of the care team matter too. Pediatric cardiac surgery requires specialised surgeons, pediatric cardiac anaesthesia, perfusion support for bypass procedures, intensive care expertise, cardiology, advanced imaging, nursing, nutrition, infection prevention and rehabilitation services. Clear communication among these disciplines helps the team anticipate challenges and adjust care promptly — arguably as important a determinant of a good result as any single skill within it.

Family involvement is meaningful as well. Parents and caregivers help the team understand the child’s usual behaviour, feeding patterns, comfort needs and developmental stage. After discharge, attending follow-up appointments, giving medications exactly as the treating doctor has prescribed, monitoring the incision, maintaining recommended nutrition and raising concerns with the care team promptly all contribute to a safer recovery.

Even after a technically successful operation, some children require lifelong follow-up. This is not a sign that surgery has failed. Congenital heart conditions can change as the child grows, and repaired valves, vessels or conduits may need monitoring. A long-term relationship with pediatric cardiology supports early identification of changes and informed planning for the future.

How Do You Choose a Children’s Heart Programme?

Parents comparing hospitals — across a country or across borders — face a wall of names and rankings. It helps to know what the names actually tell you, and what they do not.

What is the best pediatric cardiology hospital?

There is no single “best” hospital for every child, and any page that names one is selling something. Search results are dominated by large named programmes — searches such as “Presbyterian pediatric cardiology” or “Vanderbilt pediatric cardiology” reflect well-established services in the United States, and equivalent centres exist across Europe, Asia and the Middle East. What matters for your child is narrower and more concrete: does the programme regularly treat your child’s specific condition, does it have a dedicated pediatric cardiac intensive care unit, does it offer both surgical and catheter-based treatment so the choice between them is genuinely open, and does it provide structured long-term follow-up? A famous name with little experience of a rare anatomy is a worse fit than a less famous team that treats it routinely.

Who is the best pediatric heart surgeon in the world?

The honest answer is that congenital heart surgery is a team activity, and no credible ranking of individual surgeons exists. A child’s result depends on the surgeon, but also on anaesthesia, perfusion, intensive care, nursing and cardiology working as one unit through the whole admission. Rather than searching for a “best surgeon”, ask a prospective team how often they perform your child’s operation, how the case will be reviewed before a decision is made, and who will manage follow-up — the answers reveal more than any list.

Useful questions to put to any programme, anywhere in the world:

• How many children with this specific diagnosis does the team treat, and how recently?
• Is a catheter-based or staged alternative realistic for this anatomy, and why or why not?
• Who reviews the imaging before the final decision — a single doctor or a multidisciplinary board?
• What does the intensive care setup for children look like, and who staffs it overnight?
• What is the long-term follow-up plan, and how will it be shared with our doctors at home?

Pediatric Cardiac Surgery at Acibadem

Acibadem’s pediatric cardiology and cardiac surgery services are organised around individualised assessment and coordinated care for children with congenital and acquired heart conditions, drawing on the group’s wider cardiovascular surgery and pediatrics departments.

Complex cases may be reviewed through multidisciplinary specialist boards that bring together pediatric cardiologists, cardiac surgeons, anaesthetists, intensive care physicians, radiologists, genetic specialists when needed, and other pediatric professionals. This collaborative approach is particularly valuable when the diagnosis is complex, when previous surgery has been performed elsewhere, or when a family is weighing a second opinion about timing or treatment options.

Advanced cardiac imaging, pediatric catheterisation capability, surgical monitoring and specialised intensive care services support evaluation and recovery; the precise technologies used are selected according to the child’s condition and the treatment plan, not applied as a standard package. Physicians explain the diagnosis in understandable terms and discuss realistic goals of surgery. Where appropriate, the team may recommend observation, medication, catheter-based intervention, surgery, or a combination of these — treatment plans are tailored to the child rather than to a pathway.

For families arriving from abroad, international patient services assist with coordination before arrival, appointment planning, interpretation in more than 20 languages, medical record review and guidance through the hospital journey. Before returning home, families receive discharge guidance, medication instructions from the treating team, follow-up recommendations and information to share with their local pediatrician or cardiologist. For children who need continuing surveillance, the care plan can include recommendations for imaging, clinic review, activity, dental care, infection prevention and future specialist assessment.

Understanding the Road Ahead

A recommendation for pediatric cardiac surgery is a major moment for any family, but it does not have to be faced without information. Understanding the diagnosis, the reason surgery is proposed, the expected timing and the shape of recovery lets you take part in decisions rather than simply receive them.

Three ideas from this page are worth carrying with you. First, the decision to operate rests on your child’s specific anatomy and circulation — not on symptoms alone, and not on a hospital’s reputation. Second, monitoring is treatment: a team that recommends waiting, with scheduled review, is often making the safest choice available. Third, surgery is one stage in a longer relationship with cardiology that may run through childhood and beyond, and that continuity — imaging, rhythm checks, activity guidance, and honest conversations at each stage of growth — is what turns a good operation into a good life with a repaired heart.
