Pediatric heart surgery has evolved enormously with enhanced survival and quality of life for children with congenital heart disease. Methods like minimally invasive repair, hybrid procedures, and robot-assisted operations enable accurate correction of cardiac defects with less trauma. Multi-disciplinary perioperative management involving pediatric anesthesia, critical care, and rehabilitation is crucial for the best outcomes. Continuous investigation in surgical methods, imaging, and postoperative management continues to improve the efficacy of pediatric heart procedures worldwide.
