Impact of Stenting on PDA Length, Curvature, and Pulsatile Deformations Based on CT Assessment.

ABSTRACT:

Background

We sought to investigate the impact of stenting on native patent ductus arteriosus (PDA) length, curvature, and pulsatile deformations in patients with ductal-dependent pulmonary circulations.

Methods

Patients with PDA stents who received contrast-enhanced 3-dimensional computed tomography with a view of the PDA, thoracic aorta, and pulmonary arteries were retrospectively included in this study. Geometric models of the prestented and poststented PDA were constructed from the computed tomography images, and PDA arclength, curvature, and pulsatile deformations were quantified.

Results

A total of 12 patients with cyanotic congenital heart disease were included, 10 of whom received 1 stent in the PDA and 2 received multiple overlapping stents. From prestenting
