Computed Tomographic Angiography Imaging of Pediatric Congenital Heart Diseases

Background: Congenital heart diseases (CHDs) in the pediatric population present complex diagnostic challenges that often require advanced imaging modalities. While echocardiography is the initial modality of choice, it may be insufficient for visualizing extracardiac anomalies. Computed tomographic angiography (CTA) offers high-resolution, rapid imaging that is particularly beneficial for detailed anatomical assessment. Purpose: This study aims to evaluate the diagnostic utility of CTA in the assessment and characterization of various pediatric CHDs. Materials and Methods: A series of multidetector CTA scans were conducted using a 128-slice computed tomography scanner on pediatric patients with suspected or confirmed CHDs. Standard protocols with iodinated contrast were followed to optimize image quality while minimizing radiation exposure. Results: The study analyzed seven pediatric cases with different CHDs, including tetralogy of Fallot, patent ductus arteriosus, partial and total anomalous pulmonary venous return, transposition of great arteries, aortic coarctation, and truncus arteriosus. In each case, CTA provided detailed visualization of both cardiac and extracardiac structures, facilitating accurate diagnosis and aiding in treatment planning. Conclusion: CTA serves as a crucial adjunct to echocardiography in evaluating complex congenital heart anomalies. Its ability to generate rapid, high-resolution three-dimensional images of thoracic vasculature and cardiac structures makes it invaluable for comprehensive assessment, especially when surgical or interventional planning is required.
