Hearing the words “your child has a heart problem” is one of the most frightening moments a parent can face. It’s worth saying early, then, that this field has changed enormously over the past few decades – conditions that were once considered untreatable are now routinely fixed, often with a single procedure and a full recovery. Understanding what’s actually involved, and why timing and teamwork matter so much, can make an overwhelming diagnosis feel a lot more manageable.
Congenital heart disease (CHD) refers to structural problems with the heart that are present from birth – a hole between chambers, a narrowed or malformed valve, or vessels that connect in the wrong place. It’s more common than most parents realise: globally, an estimated 1 in every 100 -110 live births has some form of congenital heart defect, and in India, the figure is generally cited at around 8 – 10 per 1,000 live births – which works out to well over 200,000 babies born with a heart defect in India each year. Of these, roughly one in five has a serious defect that needs intervention within the first year of life.
Not every defect needs surgery. Many small holes or mild valve issues are monitored and close or resolve on their own. But a meaningful proportion do require a procedure – either a catheter-based fix or open surgery – to allow a child to grow and develop normally.
Because babies can’t describe what’s wrong, parents and paediatricians rely on physical clues. Signs worth taking seriously include:
It’s worth knowing that heart murmurs are common and most are entirely harmless (“innocent” murmurs, caused by normal blood flow) – the vast majority of children with a murmur do not have structural heart disease. Still, any murmur in a newborn or infant is worth a paediatric cardiology opinion simply to rule out the minority that do signal something structural, since some defects go unrecognised at birth in a straightforward physical exam alone.
Modern paediatric cardiac care has moved well beyond a one-size-fits-all surgical approach:
Two things repeatedly come up in paediatric cardiac care as decisive factors in outcomes:
Timing. Some defects are safest to fix in the first days or weeks of life; others benefit from waiting until a child is a little older and stronger. Getting this timing right – neither rushing nor delaying – is one of the most consequential decisions a paediatric cardiac team makes, and it’s highly specific to each child’s particular defect and overall health.
Teamwork. A paediatric cardiac surgery case typically involves a paediatric cardiologist (diagnosis and long-term follow-up), a cardiac surgeon, a paediatric cardiac anaesthetist, perfusionists (who manage the heart-lung bypass machine during surgery), and a dedicated paediatric cardiac ICU team for recovery. The coordination between these specialists – not any single individual’s skill alone – is consistently what separates good outcomes from great ones.
A successful repair doesn’t always mean the story ends at discharge. Many children who’ve had congenital heart surgery need periodic follow-up with a paediatric cardiologist through childhood, and increasingly, this follow-up continues into adulthood – a growing recognition in the field that children who once wouldn’t have survived infancy are now living full adult lives and need ongoing, specialised cardiac care as adults, a discipline sometimes called Adult Congenital Heart Disease (ACHD). This is a genuinely new and expanding area of cardiology, a direct consequence of how much outcomes have improved over the past generation.
Day to day, most children recover to the point of full, unrestricted activity – including sport and exercise, in the majority of straightforward repairs – though this is always something to confirm with your child’s own cardiologist rather than assume.
Not always. While pulse oximetry screening and prenatal ultrasound catch many cases early, some defects – particularly milder ones – are only picked up later, sometimes when a murmur is noted at a routine check-up or when a child shows subtle signs like poor stamina during play.
Usually not. Heart murmurs are extremely common in infants and children, and the majority are “innocent” – a normal sound of blood flow rather than a sign of a structural problem. That said, any newborn murmur deserves a paediatric cardiology opinion to rule out the minority of cases that do need attention.
It depends entirely on the defect. Simple repairs are often a single, definitive procedure. More complex conditions – particularly certain combined defects – may be managed with a staged approach over a child’s early years. Your paediatric cardiac team will map this out based on your child’s specific anatomy.
In the majority of cases, yes. Advances in paediatric cardiac surgery mean most children go on to grow, play, and develop typically after a successful repair, with periodic cardiology follow-up rather than ongoing restriction.
Don’t wait – these are signs worth an urgent paediatric evaluation. Even if the cause turns out to be unrelated to the heart, ruling out a cardiac cause quickly is always the safer path.
There’s a modestly increased risk if a parent or sibling has had a congenital heart defect, and certain genetic conditions (such as Down syndrome) are associated with a higher likelihood of heart defects. However, most cases occur without any known family history or identifiable cause.
If your child has a heart murmur, symptoms that concern you, or a known congenital heart condition, book an appointment with Kauvery Hospital’s Paediatric Cardiology team for a thorough evaluation.
