Paediatric Cardiology for NEET-SS

Why this subject matters in the exam

Paediatric Cardiology rewards reasoning from anatomy and physiology rather than rote recall. A single stem describing a cyanosed infant can test the lesion, the shunt direction, the effect of the ductus arteriosus, the expected ECG axis, the chest X-ray pattern and the emergency drug to start. The subject also overlaps with neonatology, genetics, adult cardiology and critical care. As a super-speciality paper, it treats textbook-level knowledge of the commonest lesions as the starting point, not the finishing line.

High-yield topics

• Fetal and transitional circulation: fetal shunts, changes at birth, persistent pulmonary hypertension of the newborn and the closure of the ductus arteriosus.
• Segmental approach and embryology: sequential segmental analysis, situs and looping, and the embryology of common malformations.
• Acyanotic lesions: atrial septal defect, ventricular septal defect, atrioventricular septal defect, patent ductus arteriosus, coarctation of the aorta, aortic stenosis and pulmonary stenosis, with timing and choice of closure.
• Cyanotic lesions: tetralogy of Fallot and hypercyanotic spells, transposition of the great arteries, total anomalous pulmonary venous connection, tricuspid atresia, truncus arteriosus and Ebstein anomaly.
• Duct-dependent circulations: critical aortic stenosis, hypoplastic left heart syndrome, interrupted aortic arch, prostaglandin use and its adverse effects.
• Eisenmenger syndrome and pulmonary hypertension: pathophysiology, vasodilator therapy and operability assessment.
• Single-ventricle pathway: staged palliation, bidirectional Glenn and Fontan circulation, and their long-term complications.
• Acquired heart disease: acute rheumatic fever and rheumatic heart disease, infective endocarditis, Kawasaki disease and its coronary sequelae, myocarditis and pericardial disease.
• Cardiomyopathies and heart failure: dilated, hypertrophic and restrictive types, drug therapy of paediatric heart failure, and the role of transplantation.
• Arrhythmias: supraventricular tachycardia, congenital complete heart block, long QT syndrome, Wolff-Parkinson-White syndrome, and the use of adenosine, cardioversion and pacing.
• Investigations: ECG interpretation by age, chest X-ray, echocardiography, cardiac catheterisation with oxygen saturation and pressure data, cardiac MRI and CT.
• Interventions and surgery: balloon valvotomy, device closure, stenting, surgical repair versus palliation, and perioperative care.
• Syndromic and genetic associations: Down, Turner, Noonan, Williams and 22q11 deletion syndromes, and the cardiac lesions linked to each.
• Fetal echocardiography, maternal conditions that affect the fetal heart, and screening for critical congenital heart disease by pulse oximetry.
• Special situations: syncope and chest pain in children, anticoagulation, and care of the adult with congenital heart disease.

How to study this subject

Begin with normal cardiac anatomy and the fetal circulation, then learn each lesion in the same fixed frame: anatomy, haemodynamics, clinical features, ECG, chest X-ray, echocardiographic findings, catheter data, medical management and timing of intervention. Draw the flow of blood for every lesion yourself, because shunt direction explains almost every sign and complication. Use a standard postgraduate paediatric cardiology textbook for depth and current society guidelines for practice. Practise reading ECGs, chest films and catheter tables on your own, and begin solving questions in the first weeks so that application grows alongside knowledge.

Revision strategy

Divide the syllabus into blocks, such as basics and investigations, acyanotic lesions, cyanotic lesions, acquired disease, arrhythmias and cardiomyopathies, and interventions and follow-up, and assign each block a fixed day in a weekly cycle. Condense each block into your own one-page summaries of lesion features, drug doses, thresholds and surgical timing, and revise only from those in the final weeks. Keep an error log for every wrong question, noting whether the cause was a knowledge gap, a misread stem or confusion between two similar lesions, and review it weekly. In the last month, attempt full-length mocks in exam conditions and analyse each paper in detail before moving on.
