Figure 1 Example of a reconstructed aorta overlaying a narrowed left pulmonary artery. The Journal of Thoracic and Cardiovascular Surgery 2010 139, 557-561DOI: (10.1016/j.jtcvs.2009.08.023) Copyright © 2010 Terms and Conditions

Figure 2 Skeletonization view of the aorta–left pulmonary artery overlap region. Ribbons are cross-sections of the respective vessels. The minimum left pulmonary artery area was located, followed by the area of the transverse aortic cross-section closest to the minimum left pulmonary artery location.

Figure 3 Scatter plot of measured transverse aortic and left pulmonary artery (LPA) diameters for the non–hypoplastic left heart syndrome (NHLHS) and hypoplastic left heart syndrome (HLHS) patient groups. The solid and dashed lines represent normal LPA and transverse aortic dimensions, respectively, in healthy children. BSA, Body surface area.

Figure 4 Comparison between aortic and left pulmonary artery (LPA) sizes at the junction across the hypoplastic left heart syndrome (HLHS) and non–hypoplastic left heart syndrome (NHLHS) patient groups (A) and patients with reconstructed arteries (RA) and nonreconstructed arteries (NRA) (B), respectively. ∗P < .05.
