| Abstract | ||||
| Background: Tetralogy of Fallot (TOF), recognized as the most prevalent form of cyanotic congenital heart disease, is characterized by a constellation of four anatomical defects: a ventricular septal defect, an overriding aorta, right ventricular outflow tract obstruction, and right ventricular hypertrophy. Despite substantial advancements in early surgical correction that have markedly enhanced survival outcomes, lifelong surveillance remains essential due to the persistent risk of residual anomalies and late-onset complications. Echocardiography has traditionally been the first-line imaging modality for diagnosing and monitoring TOF, but its limitations in visualizing extracardiac structures and complex vascular anomalies pose challenges, especially in preoperative planning. Objective: This review explores the evolving role of multislice computed tomography (MSCT) in the assessment of TOF, comparing it with echocardiography. It highlights MSCT's advantages in anatomical visualization, coronary artery evaluation, and preoperative planning. Methods: A comprehensive review of the literature from PubMed, Scopus, and Web of Science was conducted, focusing on studies comparing MSCT and echocardiography in the evaluation of TOF. Key aspects of MSCT technology, including advances in spatial and temporal resolution, were examined, along with its applications in preoperative planning, postoperative evaluation, and long-term follow-up. Conclusion: MSCT offers superior imaging capabilities for detailed assessment of both intracardiac and extracardiac anatomy, including coronary artery anomalies and pulmonary vasculature, making it a valuable complement to echocardiography. Future advancements in MSCT technology, along with hybrid imaging approaches, hold the potential to enhance diagnostic accuracy and clinical outcomes in patients with TOF. | ||||
