Purpose: To determine the type of pulmonary circulation (PC) in patients with tetralogy of Fallot (TOF) and pulmonary atresia (TOF-PA) with the use of computed tomographic angiography (CTA), and describe their clinical courses, corrective surgery and disease burden.
Methods: 145 patients (median age 4 years, interquartile range: IQR2-8 years) were analyzed for PC which divided into 5 CTA-types and 11 subtypes based on presence of main pulmonary trunk (MPA) and confluent pulmonary arteries (confluence-PAs), presence of ductus arteriosus or major aortopulmonary collateral arteries (MAPCAs), respectively. Pulmonary arteries (PAs) were assessed by McGoon ratio and arborization. Read More
