Every heartbeat tells a story, but for thousands of infants in India, that story being interrupted before it truly begins. Despite the leap in robust screening programmes, nearly one-fifth of children with Congenital Heart Disease (CHD) remain invisible to the healthcare system until it is nearly too late. This delay in diagnosis usually due to to a lack of screening or clinical awareness, transforms treatable conditions into life-threatening hurdles. For these children, the difference between a future full of potential and a life of disability comes down to the timing of a single scan. It is a race against the clock where early detection is the only finish line that matters – Dr Atul Surendra Prabhu, Consultant, Cardiology – Paediatric, Narayana Healthcity, Bangaluru

The First Line of Defense: Antenatal Screening
The journey to a healthy heart does not actually start at birth; rather, it begins before that when life starts in the womb. By utilizing the 18 to 20 week anomaly scan, doctors can identify up to 85 percent of major cardiac anomalies. This early window allows parents to undergo a fetal echocardiogram, providing the necessary time to prepare mentally and medically for any interventions required immediately after delivery.
The Role of Prevention
Prevention also plays a critical role long before a mother enters the delivery room. While only about 4 percent of heart defects are strictly hereditary, the environment of the developing fetus is paramount. Experts strongly advise that women planning a pregnancy begin a regimen of folic acid and multivitamins at least six months before conception. This ensures that levels of Vitamin A, D, and folic acid are adequate during the most sensitive stages of heart development. Furthermore, any woman on chronic medication should consult her physician to switch to alternatives which do not harm the fetus before conceiving, ensuring the upcoming fetus is shielded from avoidable chemical stressors.
Red Flags for Parents
Once the baby is born, the first three months are the most critical window for observation. Parents and caregivers must be vigilant for subtle signs of distress that often mistaken for common ailments. A primary indicator is the “suck-rest-suck” cycle, where an infant is unable to feed continuously because they lack the energy or oxygen to breathe and swallow simultaneously. Other red flags include excessive sweating during feeding, a bluish tint to the lips or skin known as cyanosis, and a general failure to thrive. It often noted that when a three-month-old presents with severe, or frequent pneumonia, the cause could often be an underlying heart defect rather than a usual respiratory infection.
Beyond Structural Defects: The “Electrical” Heart
Beyond the physical structure of the heart, there is the often-overlooked electrical system. Roughly one-quarter of children with heart issues suffer from rhythm problems, such as an extremely slow heartbeat or a racing heart that the child may describe as chest pain. These electrical “short circuits” can change a child’s personality, making them timid or prone to what misdiagnosed as panic attacks. Modern pediatric electrophysiology now allows doctors to correct these issues through specialized procedures as early as age five, often eliminating the need for long-term medication and its associated side effects.
As these children grow, a new challenge emerges: the transition from pediatric to adult care. In India, many patients who operated on as children or diagnosed late in adolescence fall into a “care gap.” This has led to the emergence of G.U.C.H. (Grown-Up Congenital Heart) disease as a specialized field. Whether it is a young woman discovering a heart defect during the stress of her first pregnancy or a young man finding he cannot keep up with his peers at the gym, the need for lifelong surveillance . Cardiologists need extensive training and experience to evaluate and manage the GUCH cases.
Closing the Gap: From Infancy to Adulthood
Ultimately, the goal of modern pediatric cardiology is to move toward a more structured and mandatory screening system. Implementing universal pulse oximetry for every newborn can catch defects that the naked eye might miss. When a heart disease detected and managed within the first year of life, the success rate and overall quality of life improve by more than 70 percent across all categories. By shifting the focus toward early antenatal screening and specialized pediatric care, we can ensure that children with heart defects do not just survive, but grow to lead completely normal, active lives.
