Preoperative Computed Tomographic Angiography Can Predict Need for Branch Pulmonary Artery Intervention in Patients With Ductal-Dependent Pulmonary Blood Flow.

Background: Neonates with ductal-dependent pulmonary blood flow (DD-PBF) are at risk for pulmonary artery (PA) stenosis. The objective of this study was to identify preoperative cardiovascular computed tomography angiography (CTA) measures that are associated with the need for branch PA intervention.

Methods: We identified neonates with DD-PBF who underwent preoperative CTA at our center and were followed for 24 months.
