Congenital heart defects are among the most common birth defects, affecting approximately 1 in 100 newborns. Some defects may resolve on their own or remain asymptomatic, but others can lead to serious complications such as heart failure, growth retardation, or even mortality if left untreated. Pediatric cardiac surgery is essential for correcting these defects, improving the quality of life, and increasing the chances of survival for affected children.
