Pictorial review highlights CCTA's diagnostic utility in planning treatment for congenital heart disorders.
Pediatric congenital right heart obstructive lesions encompass a spectrum of diseases that obstruct blood flow from the right atrium to the pulmonary artery. Right ventricular inflow obstructions include tricuspid valve abnormalities, such as Ebstein anomaly, tricuspid valve dysplasia, and tricuspid atresia. Right ventricular outflow obstructions include pulmonary valve stenosis, pulmonary atresia, and tetralogy of Fallot. Cardiac computed tomography angiography (CCTA) is a valuable tool for the diagnosis, treatment planning, and follow-up of these lesions. In this pictorial review, we highlight the diagnostic utility of CCTA in congenital right heart obstructive lesions, emphasizing its role in preoperative planning.
