Congenital heart defects (CHDs) encompass structural abnormalities that manifest at birth, exerting an impact on both the form and function of the heart. These defects arise during fetal development when the heart is forming, and they can involve the heart valves, walls, arteries, or veins. CHDs vary widely in severity, with some causing minor issues and others posing life-threatening challenges. While the exact cause of most congenital heart defects remains unknown, certain factors such as genetic predisposition, maternal health, and environmental influences may contribute. The symptoms and consequences of CHDs can manifest at different stages of life, necessitating early detection and intervention. Advances in medical technology and surgical techniques have significantly improved the prognosis for individuals with congenital heart defects, allowing many to lead fulfilling and relatively normal lives with appropriate medical care and support. However, ongoing research and awareness efforts are crucial to further understand and address the complexities of congenital heart defects, ultimately improving outcomes and quality of life for those affected.
