Valve-sparing aortic root replacement after neonatal arterial switch operation

Adishesh K Narahari et al. J Card Surg. 2021 Jun.

Abstract

Arterial switch operations (ASO) are lifesaving procedures performed on neonates to treat transposition of the great arteries. However, future operations on the neoaorta may be required due to dilation. We present a case of a 25-year-old female who presented with dilation of her neoaorta and required a David procedure. Her previous ASO resulted in an anterior lie of the pulmonary artery in front of the neoaorta, with both coronary arteries coming off anteriorly. We describe our approach to performing a David procedure on this patient with this unique anatomy.

Keywords: aorta and great vessels; congenital heart disease.

ECG-Gated CT Angiography with 3D postprocessing is shown for images pre-surgery. 3D volume rendered CTA images from multiple orientations are shown in A)-D). The overlying pulmonary artery is shown with a yellow oval (A) and the location of the incision of the left pulmonary artery is shown with a yellow arrow (C). Reconstructed images with the right ventricle removed are shown in B) and D) to view the aortic root aneurysm.
