Congenital heart defects (CHDs) stand as the most prevalent type of birth defects globally. With advancements in medical care and treatment, babies born with CHDs are experiencing longer and healthier lives. Let’s delve deeper into the world of CHDs to understand their complexities and impact.
Understanding Congenital Heart Defects (CHDs)
CHDs manifest at birth, affecting the heart’s structure and functionality. According to Dr Zakia Khan, Senior Consultant- Interventional Cardiology, Fortis Hospital, Kalyan, CHDs alter the normal flow of blood through the heart and may range from mild, such as a small hole, to severe, involving missing or poorly formed heart components. Critical CHDs, affecting 1 in 4 babies with heart defects, demand immediate surgical or procedural interventions within the first year of life.
Types Of Congenital Heart Defects
The spectrum of CHDs includes diverse types, each presenting unique challenges. Some prominent CHDs include:
- Atrial Septal Defect
- Atrioventricular Septal Defect
- Coarctation of the Aorta
- Double-outlet Right Ventricle
- d-Transposition of the Great Arteries
- Ebstein Anomaly
- Hypoplastic Left Heart Syndrome
- Interrupted Aortic Arch
- Pulmonary Atresia
- Single Ventricle
- Tetralogy of Fallot
- Total Anomalous Pulmonary Venous Return
- Tricuspid Atresia
- Truncus Arteriosus
- Ventricular Septal Defect
Signs and Symptoms of CHDs
The manifestation of CHD symptoms varies depending on the defect’s severity and type. While some defects may present minimal or no symptoms, others may lead to:
- Bluish discoloration in nails or lips
- Fatigue or lethargy during feeding
- Rapid or labored breathing
- Excessive sleepiness
How Are CHDs Diagnosed?
CHDs may be identified during pregnancy through specialized imaging techniques like fetal echocardiography. However, some defects remain undetected until after birth or later in life, necessitating postnatal assessments. Diagnostic procedures such as echocardiograms play a pivotal role in confirming CHD diagnoses.
What Are Possible Treatment Approaches for CHDs?
The treatment regimen for CHDs is tailored to suit each defect’s type and severity. It spans a spectrum from surgical interventions aimed at repairing cardiac structures to minimally invasive procedures like cardiac catheterization. Continuous post-treatment monitoring and follow-up care are integral components of CHD management to ensure optimal outcomes.
Causes of CHDs
While the precise etiology of CHDs often remains elusive, genetic predispositions, environmental factors, maternal health conditions, and medication use during pregnancy are implicated. Conditions like pre-existing diabetes, maternal obesity, and prenatal exposure to smoking or certain medications elevate the risk of CHDs in newborns.

Recent advancements in medical interventions have significantly improved the life expectancy and quality of individuals with CHDs. Many children diagnosed with CHDs now transition into adulthood, underscoring the importance of lifelong care and monitoring. Regular consultations with cardiologists enable early detection of potential complications and facilitate proactive management strategies.
In conclusion, International CHD Awareness Month serves as a poignant reminder of the prevalence and impact of congenital heart defects worldwide. By fostering awareness, promoting early detection, and advancing treatment modalities, we strive to enhance the well-being and longevity of individuals affected by CHDs. Together, let us advocate for greater understanding and support for those living with CHDs.
