Tetralogy of Fallot is one of the most common cyanotic congenital heart defects in children, characterized by a combination of four anatomical abnormalities: ventricular septal defect, pulmonary stenosis, right ventricular hypertrophy, and overriding aorta. This study focuses on the clinical presentation, diagnostic approaches, and treatment tactics of Tetralogy of Fallot in pediatric patients. Early recognition of symptoms such as cyanosis, dyspnea, developmental delay, and hypoxic spells plays a crucial role in timely intervention. Echocardiography remains the gold standard for diagnosis, providing essential information for surgical planning. Both palliative and radical surgical corrections significantly improve survival and quality of life in affected children. The study also underlines the importance of postoperative rehabilitation and long-term cardiological follow-up in ensuring favorable outcomes.
