A diet for children with pulmonary hypertension should focus on low-sodium, nutrient-dense whole foods that support heart and lung function. Key priorities include limiting processed food and added salt, ensuring adequate protein for muscle strength, managing total fluid intake and maximising vitamins C, D and iron.

“Families focus almost entirely on medications and rightly so but nutrition is the one thing happening three times a day every day that nobody is optimising and in a child with pulmonary hypertension that’s a significant missed opportunity for supporting the heart,” says Dr. Prashant Bobhate, Pediatric Cardiologist in Mumbai, India.

There’s a recognisable list and understanding it is what makes pre-participation cardiac screening a clinical necessity rather than an optional extra for competitive sport.

• Hypertrophic cardiomyopathy: The single most common cause in young athletes where abnormally thickened myocardial fibres create an unstable electrical substrate that generates ventricular fibrillation under the precise haemodynamic stress that intense physical exertion produces.
• Anomalous coronary arteries: A coronary artery arising from the wrong sinus can course between the aorta and pulmonary artery in a way that compresses the vessel during exercise-induced aortic expansion and cuts off blood supply to a large myocardial territory at exactly the moment demand is highest.
• Long QT syndrome: The ECG looks almost normal at rest but the prolonged repolarisation interval becomes dangerous under adrenergic stimulation from exercise or sudden emotional stress and can trigger torsades de pointes that degenerates into ventricular fibrillation without any warning symptom.
• Myocarditis: Viral inflammation of the heart muscle creates zones of electrical instability that persist well beyond the acute illness phase and an athlete who returns to training too soon after a viral illness with unrecognised myocarditis is training on a heart that can no longer reliably maintain normal rhythm under load.

Every young athlete with a family history of sudden cardiac death, unexplained syncope during exercise or a newly detected murmur deserves a formal assessment and pediatric arrhythmia evaluation maps the electrical and structural risk before any return to competitive sport gets cleared.

Often yes. When the right screening happens before the right sport at the right intensity.

• Pre-participation ECG: A resting 12-lead ECG picks up Long QT syndrome, WPW pattern, Brugada pattern and HCM-related repolarisation changes that a physical examination alone completely misses and costs a fraction of what treating a survivor of cardiac arrest costs in every dimension imaginable.
• Echocardiography for high-risk athletes: Any athlete with an abnormal ECG, a family history of sudden cardiac death under 50, unexplained exertional syncope or a cardiac murmur needs an echo before competing at any level where sustained high-intensity effort is involved.
• Restricting sport in diagnosed conditions: A child diagnosed with HCM, Long QT or anomalous coronary arteries needs a formal sport eligibility assessment because the specific activity restriction required is condition-specific and a blanket ban applied without assessment is as clinically unhelpful as no restriction at all.
• AED availability at sports venues: Automated external defibrillators at schools, sports academies and training grounds don’t prevent the arrhythmia but they convert a potentially fatal event into a survivable one when used within the first three to five minutes and their absence at Indian sports venues is a preventable gap that costs young lives every year.

Parents wanting to understand what cardiac warning signs in young children look like before any sport-related event forces the issue should read this piece on how to spot the early signs of heart disease in neonates because the cardiac conditions that cause sudden death in athletes at sixteen were present at birth and detectable long before the first sprint.

Pre-participation cardiac screening for a young athlete isn’t a routine check. It’s reading an ECG in the context of the sport being played, the intensity involved and the specific conditions that that particular child’s family history or symptom profile makes worth looking for. Not a form-filling exercise. A real assessment.

The goal is calorie-dense, nutrient-rich food that doesn’t overload the circulation, supports cardiac muscle function and maintains a body weight the right ventricle can actually sustain without additional strain.

• Adequate calories: Children with PH burn more calories than healthy peers because increased work of breathing and cardiac effort raises resting energy expenditure and underfeeding a child with PH isn’t cautious it’s actively harmful to the right ventricle’s ability to cope.
• Protein for muscle strength: Adequate dietary protein from eggs, lentils, dairy and lean meats supports respiratory muscle strength and prevents the muscle wasting that significantly worsens functional capacity and exercise tolerance in children with chronic cardiopulmonary disease.
• Vitamins C and D: Vitamin C from fresh fruits and vegetables supports vascular integrity and immune function while vitamin D deficiency is common in children with chronic cardiac disease and contributes to muscle weakness, fatigue and poor bone health that compounds the disease burden.
• Iron-rich foods: Many children with cyanotic PH develop iron deficiency alongside erythrocytosis and ensuring adequate dietary iron through lentils, green leafy vegetables and fortified cereals supports healthy red cell production without the risks of unmonitored supplementation.

Understanding how nutrition fits into the broader management picture for children with pulmonary hypertension is exactly what a thorough medical management of pulmonary hypertension consultation covers alongside medication planning and follow up.

Specific things make the right heart’s job harder. Worth knowing clearly.

• High sodium foods: Processed snacks, packaged noodles, pickles, papads and restaurant food carry sodium loads that drive fluid retention in children whose kidneys are already responding to reduced cardiac output by retaining more salt and water than they should.
• Large meals: Big meals shift significant blood volume to the gut during digestion and in children with limited cardiac reserve that sudden redistribution triggers breathlessness, fatigue and reduced oxygen saturation so smaller more frequent meals across the day are always the better approach.
• Grapefruit: Grapefruit and grapefruit juice inhibit the enzyme that metabolises several PH medications including sildenafil and bosentan and consuming it regularly alters effective drug levels in ways that are genuinely unpredictable and clinically significant for a child already on a carefully titrated regimen.
• Caffeine: Caffeinated drinks including cola, energy drinks and strong tea can trigger arrhythmias and raise heart rate in children whose cardiac rhythm is already more vulnerable than in a healthy child and these simply don’t belong in a PH child’s regular diet.

Parents wanting to understand the broader treatment approach for children on active PH therapy should also read about PH differences, as understanding related heart and lung conditions helps families better follow long-term management decisions

Yes, Most women with congenital heart disease can safely have children but pregnancy carries real risks including arrhythmia, heart failure and stroke that vary significantly by defect type and repair history. It requires specialised care from a team including a cardiologist and maternal-fetal medicine specialist and that conversation needs to start before conception not after a positive test arrives.

“I’ve seen women with complex congenital heart disease carry pregnancies to term and do well and I’ve seen women with seemingly simple repaired defects run into problems nobody anticipated because nobody did a proper pre-conception cardiac evaluation before they conceived,” says Dr. Prashant Bobhate, Pediatric Cardiologist in Mumbai, India.

Pregnancy puts the cardiovascular system under a sustained haemodynamic load and a heart already managing abnormal anatomy handles that load very differently from a structurally normal one.

• Blood volume surge: Pregnancy increases blood volume by 40 to 50 percent and a heart with limited functional reserve can decompensate rapidly under that sustained demand even if it was compensating adequately before conception.
• Arrhythmia risk: The haemodynamic and hormonal changes of pregnancy lower the arrhythmia threshold and atrial flutter, SVT and ventricular arrhythmias can emerge in women who had no rhythm history whatsoever before conceiving.
• Pulmonary hypertension: Women with pulmonary arterial hypertension face the highest maternal mortality risk of any cardiac condition in pregnancy because systemic vasodilation against fixed pulmonary vascular resistance can deteriorate rapidly and catastrophically.
• Fontan circulation: The passive pulmonary blood flow that sustains a Fontan depends on venous pressure gradients that pregnancy disrupts and obstetric outcomes in Fontan patients need the most experienced multidisciplinary team available.

Every woman with a congenital heart diagnosis considering pregnancy deserves a full structural and functional assessment and congenital heart disease evaluation before conception maps current anatomy, ventricular function and pulmonary pressures before any pregnancy planning moves forward.

Planned, monitored and never managed alone by a single specialist.

• Pre-conception counselling: A cardiac assessment before attempting pregnancy establishes the current baseline of ventricular function, pulmonary pressure and rhythm status so any changes during pregnancy can be measured against something real rather than guessed at.
• Medication review: Several cardiac medications including warfarin, ACE inhibitors and some antiarrhythmics carry real fetal risk and switching to pregnancy-safe alternatives before conception is far safer than scrambling to change them after a positive test.
• High-risk obstetric co-management: A maternal-fetal medicine specialist needs to be part of the team from the start because delivery timing, mode of delivery and anaesthetic approach all have cardiac implications that require both teams aligned well before the moment arrives.
• Delivery planning: Women with significant CHD need delivery at a centre with cardiac anaesthesia, adult congenital cardiology and a cardiac ICU on site because the haemodynamic shift immediately after delivery is one of the highest-risk moments in the entire pregnancy.

Parents wanting to understand the long-term journey of congenital heart care should also explore surgery costs, as treatment planning often begins early and financial preparation plays an important role in managing cardiac care from childhood onward

A woman with congenital heart disease who wants to have children needs a cardiologist who understands what her specific anatomy does under the haemodynamic load of pregnancy, can advise on medication changes before conception and can coordinate with the obstetric team across the full nine months rather than showing up only when something goes wrong. Dr. Prashant Bobhate has spent over 12 years managing adult congenital heart disease including pre-conception counselling and pregnancy planning for women with complex repaired and unrepaired cardiac conditions at the Children’s Heart Centre, Kokilaben Dhirubhai Ambani Hospital.

Around 240,000 babies are born with congenital heart disease in India every year, roughly one in every 100 newborns, making it the leading cause of birth defect-related deaths and accounting for nearly 10 percent of all infant deaths in the country. The defects are present. The surgical solutions exist. The gap that kills children sits between those two facts and in 2026 that gap is still far wider than it should be.

“The numbers are not abstract to me. Every year tens of thousands of Indian children who could have been saved with a timely intervention aren’t and the reason is almost never that the surgery was too difficult. It’s that nobody found them early enough or the family couldn’t access the right centre in time” says Dr. Prashant Bobhate, Pediatric Cardiologist in Mumbai, India.

It creates a deliberate right-to-left shunt at the level of the great vessels that allows the overloaded right ventricle to decompress directly into the aorta rather than continuing to push against a pulmonary vascular resistance it can no longer overcome.

• Right ventricular decompression: The shunt allows blood to bypass the high-resistance pulmonary circulation entirely which immediately reduces the pressure load on a right ventricle that was heading toward failure and gives the chamber a chance to recover function it was rapidly losing.
• Maintains cardiac output: A failing right ventricle in severe PH can no longer maintain adequate systemic circulation and the Potts shunt preserves overall cardiac output even at the cost of some arterial oxygen desaturation which is an acceptable trade-off when the alternative is right heart collapse.
• Bridge to transplant: In children who are maxed out on medical therapy and deteriorating despite everything, the Potts shunt buys enough haemodynamic stability to reach lung transplant listing criteria and survive the wait in a condition where transplant is actually still feasible.
• Transcatheter approach: India’s first successful transcatheter Potts shunt was performed at this centre using a catheter-based technique rather than open surgery which reduces the procedural risk significantly in children who are already haemodynamically fragile and couldn’t safely tolerate a sternotomy at that point in their disease.

Understanding what interventional options exist for children with severe pulmonary hypertension who have exhausted conventional medical pathways is exactly what a thorough interventional treatment for pulmonary hypertension assessment maps out before any decision gets made.

Better than a decade ago, but still nowhere near where they should be

• Better Surgical Outcomes: Leading Indian paediatric cardiac centres now achieve outcomes comparable to global standards for common congenital heart surgeries when treated early
• Delayed Diagnosis Risk: Many children reach surgery late with complications like malnutrition or pulmonary hypertension, which worsens recovery
• Ayushman Bharat Support: PM-JAY has improved affordability, but specialist care remains concentrated in limited cities
• Fetal Diagnosis Advantage: Early detection through fetal echocardiography improves outcomes by enabling timely referral before complications develop 

Parents wanting to understand why fetal cardiac detection matters should read about the importance of fetal diagnosis of critical congenital heart disease, as early detection can mean the difference between planned care and an emergency after birth.

The statistics describe a system problem. What matters to any individual family is whether the specialist in front of them has the training, the equipment and the experience to find the defect early, make the right call about timing and intervention and follow that child for as long as the heart needs watching.

The Potts shunt is a surgically or catheter-created connection between the left pulmonary artery and the descending aorta that gives the right ventricle a pressure release valve when pulmonary hypertension has become so severe the right heart can no longer sustain it safely on its own. It doesn’t cure pulmonary hypertension.

“The Potts shunt is one of the most misunderstood procedures in paediatric pulmonary hypertension care because families hear it described as a last resort and immediately interpret that as giving up when it’s actually the opposite.” says Dr. Prashant Bobhate, Pediatric Cardiologist in Mumbai, India.

It creates a deliberate right-to-left shunt at the level of the great vessels that allows the overloaded right ventricle to decompress directly into the aorta rather than continuing to push against a pulmonary vascular resistance it can no longer overcome.

Understanding what interventional options exist for children with severe pulmonary hypertension who have exhausted conventional medical pathways is exactly what a thorough interventional treatment for pulmonary hypertension assessment maps out before any decision gets made.

A very specific group. Not every child with PH. Not even every child with severe PH.

• Suprasystemic RV pressure: Children whose right ventricular pressure has risen above systemic pressure on maximal combination medical therapy are the primary candidates because at that level the right heart is in imminent danger of irreversible failure and the shunt is the only intervention that immediately addresses the mechanical crisis.
• Failing on maximal therapy: A child already on triple combination PH therapy including a prostacyclin who continues to deteriorate clinically and haemodynamically is telling you the medical ceiling has been reached and the next decision is either the Potts shunt or palliative management with no bridge to anything.
• Pre-transplant stabilisation: Children being evaluated for lung transplant who are too unstable to survive the wait on medical therapy alone are given the Potts shunt to stabilise their haemodynamics long enough to get listed, wait and reach the transplant in a condition where it can actually succeed.
• Not suitable for everyone: Children with significant left heart disease, severe aortic regurgitation or unfavourable anatomy at the shunt site aren’t candidates and the decision requires detailed catheterisation data, imaging and a team that has actually performed this procedure rather than read about it.

Parents wanting to understand how severe pulmonary hypertension can progress and why options like Potts shunt may become necessary should also read about when lung transplant is needed in pulmonary hypertension.
