Congenital heart defects (CHDs) are anomalies in the heart's structure present at birth, impacting its form and function. These defects originate during fetal development, affecting components like heart valves, walls, arteries, or veins. The severity of CHDs varies, ranging from minor issues to potentially life-threatening complications. While the exact causes of most congenital heart defects remain elusive, factors such as genetic predisposition, maternal health, and environmental influences are believed to play a role. The symptoms and implications of CHDs may surface at different life stages, underscoring the importance of early detection and timely intervention. The management of congenital heart defects has witnessed remarkable progress due to advances in medical technology and surgical techniques. These developments have significantly enhanced the prognosis for individuals with CHDs, enabling many to lead fulfilling and relatively normal lives with appropriate medical care and support. Nonetheless, ongoing research efforts are essential to deepen our understanding of the intricacies surrounding congenital heart defects.
