Socio Today
Medical experts and pediatric specialists are raising urgent awareness regarding the subtle yet critical indicators of Congenital Heart Disease (CHD) in infants and children, emphasizing that early identification is the most significant factor in reducing mortality and improving long-term health outcomes. Dr. Rizky Adriansyah, Chairman of the Cardiology Coordination Unit of the Indonesian Pediatric Society (IDAI), recently highlighted that one of the most prevalent and easily observable signs of a potential heart defect is a child’s persistent difficulty in gaining weight. Speaking during an IDAI media briefing held virtually on Tuesday, February 14, 2023, Dr. Rizky noted that while some symptoms of heart disease are dramatic, many are insidious, leading to frequent misdiagnoses and delayed treatment.
Congenital Heart Disease, known in Indonesia as Penyakit Jantung Bawaan (PJB), refers to structural or functional abnormalities of the heart that are present from birth. these defects occur during the critical early stages of fetal development in the womb, often before a mother even realizes she is pregnant. These abnormalities can involve the heart walls, the heart valves, or the large blood vessels that carry blood to and from the heart. According to data from the United States, approximately 35,000 infants are born with these conditions annually, making it one of the most common types of birth defects globally. In the Indonesian context, where birth rates remain high, the number of children requiring specialized cardiac care is substantial, necessitating a robust public health strategy focused on early screening.
Understanding the Spectrum of Symptoms and the Risk of Misdiagnosis
The primary challenge in managing CHD lies in the overlap of its symptoms with more common childhood ailments. Dr. Rizky pointed out that many children suffering from undiagnosed heart conditions are frequently misdiagnosed with respiratory issues such as asthma. This occurs because CHD often manifests as shortness of breath (dyspnea) and rapid fatigue during physical activity or even during routine tasks like breastfeeding for infants.
"The signs and symptoms of CHD in children that are most common and easiest to recognize involve weight gain issues," Dr. Rizky explained. He elaborated that when a child’s heart is not functioning efficiently, the body consumes an enormous amount of energy simply trying to maintain circulation and oxygenation. Consequently, very little energy is left for growth and weight gain, leading to "failure to thrive."
Furthermore, parents are urged to be vigilant regarding recurring illnesses. Dr. Rizky noted that children with heart defects are significantly more susceptible to respiratory infections. It is common for these children to experience repeated bouts of pneumonia, chronic coughing, or flu-like symptoms that seem to resolve only to return shortly thereafter. This cycle of illness is often a byproduct of "pulmonary overcirculation," where a hole in the heart or a malformed vessel causes too much blood to flow to the lungs, making them congested and prone to infection.
The Role of Echocardiography in Modern Diagnostics
When clinical symptoms suggest a cardiac issue, the definitive next step is specialized diagnostic imaging. Dr. Rizky strongly recommends that parents whose children exhibit these symptoms seek a consultation with a pediatric cardiologist for an echocardiography. Commonly referred to as a heart ultrasound, an echocardiogram uses high-frequency sound waves (ultrasonic waves) to create live images of the heart’s structure and function.
This non-invasive technology allows physicians to observe the heart’s chambers, valves, and blood flow patterns in real-time. It can detect "holes" in the heart (such as Atrial Septal Defects or Ventricular Septal Defects), valve narrowings (stenosis), or complex transpositions of the great arteries. Beyond structural defects, echocardiography is also instrumental in identifying heart rhythm abnormalities (arrhythmias) that could pose a sudden risk to a child’s life.
The advancement of medical technology has moved the diagnostic window even earlier. Dr. Rizky emphasized that fetal echocardiography can now be performed as early as the 16th week of pregnancy, once the fetal heart structure is sufficiently developed. Detecting a heart defect while the child is still in the womb allows medical teams to prepare for immediate postnatal intervention, which can be the difference between a successful recovery and a fatal outcome.
Global Prevalence and the Indonesian Context
The data regarding CHD underscores a significant global health burden. While the American survey cited by Dr. Rizky mentions 35,000 cases annually, global estimates from the World Health Organization (WHO) suggest that nearly 1 in every 100 children is born with some form of heart defect. In Indonesia, with a population of over 270 million, the prevalence translates to tens of thousands of new cases every year.
The IDAI has been proactive in advocating for better screening protocols across the Indonesian archipelago. The challenge remains the unequal distribution of pediatric cardiologists and specialized cardiac centers, which are often concentrated in major urban hubs like Jakarta and Surabaya. For families in rural areas, the "silent" symptoms of CHD—such as slow weight gain—might be attributed to malnutrition or poor sanitation, delaying the necessary cardiac referral until the child reaches a state of heart failure.
Chronology of Detection and Intervention
The timeline for managing CHD is divided into three critical phases: prenatal, neonatal, and early childhood.
- The Prenatal Phase (16–24 Weeks Gestation): This is the ideal window for fetal echocardiography. If a defect is found, the delivery can be planned at a tertiary hospital equipped with a Neonatal Intensive Care Unit (NICU) and pediatric cardiac surgeons.
- The Neonatal Phase (Birth to 28 Days): Newborn screening using pulse oximetry (measuring oxygen levels in the blood) is a simple, cost-effective way to detect "critical" CHD, where the baby might look healthy but has dangerously low oxygen levels.
- The Early Childhood Phase: This is when symptoms like poor weight gain, frequent pneumonia, and exercise intolerance become most apparent. Dr. Rizky notes that this is the stage where parental observation is most vital.
Analysis of Implications: Public Health and Economic Impact
The implications of late-detected CHD are profound, both for the individual family and the national healthcare system. When a heart defect is caught late, the heart may have already undergone irreversible remodeling or the lungs may have developed permanent damage (pulmonary hypertension). In such cases, the complexity and cost of surgery increase exponentially, and the prognosis for the child diminishes.
From a public health perspective, investing in early screening and parental education is far more cost-effective than treating late-stage heart failure. In Indonesia, the Social Security Administrator for Health (BPJS Kesehatan) covers many cardiac procedures, but the backlog for surgeries can be long. Early diagnosis allows for "interventional cardiology"—non-surgical procedures using catheters to plug holes or open valves—which are less invasive, have shorter recovery times, and are generally less expensive than open-heart surgery.
Moreover, the psychological toll on families cannot be overlooked. The "recurring illness" cycle mentioned by Dr. Rizky often leads to parental exhaustion and financial strain due to constant outpatient visits. Educating parents to recognize that a "respiratory" issue might actually be a "cardiac" issue empowers them to demand the correct diagnostic tests sooner.
Official Response and Recommendations from IDAI
The Indonesian Pediatric Society continues to push for a standardized screening protocol for all newborns across the country. Dr. Rizky and his colleagues emphasize that "early detection is crucial to prevent further damage and even death in infants." The IDAI’s stance is that no child should reach a state of advanced heart failure because of a missed diagnosis in infancy.
Medical professionals recommend that pediatricians and general practitioners at the primary care level (Puskesmas) pay closer attention to growth charts. If a child’s weight gain is plateauing despite adequate caloric intake, a cardiac screening should be considered a priority rather than an afterthought.
In conclusion, the message from the medical community is clear: awareness is the first line of defense. By understanding that poor weight gain and frequent respiratory infections can be symptoms of an underlying heart defect, parents and healthcare providers can work together to ensure that children with Congenital Heart Disease receive the life-saving interventions they need at the earliest possible stage. The integration of advanced diagnostics like echocardiography into routine prenatal and pediatric care remains the gold standard for protecting the hearts of the next generation.
