Childhood heart diseases refer to a range of congenital and acquired conditions affecting the heart in children. While some heart issues may be present at birth, others can develop during childhood due to various factors. Congenital heart defects, structural abnormalities present at birth, are among the most common forms of childhood heart diseases. These defects can affect the heart's valves, chambers, or blood vessels, compromising its ability to pump blood effectively. Acquired heart conditions in children may result from infections, inflammatory disorders, or complications from other health issues. Timely diagnosis and medical intervention are crucial to manage childhood heart diseases, as they can significantly impact a child's overall well-being and development. Advances in medical technology and surgical techniques have improved the prognosis for many children with heart conditions, highlighting the importance of early detection and comprehensive medical care in addressing these challenges. Regular check-ups and a collaborative approach between healthcare professionals and families are essential for managing childhood heart diseases and improving the quality of life for affected children.
