High-Resolution CT–Based Virtual Simulation of an Unruptured Sinus of Valsalva Aneurysm for Aortic Root Reimplantation: A Case Report

INTRODUCTION: Valve-sparing aortic root replacement (VSRR) for sinus of Valsalva aneurysm (SVA) is rarely reported due to technical challenges. In this case report, high-resolution CT data were used for 3D computer graphics (3DCG) visualization and precise measurement of aortic root geometry, facilitating VSRR in a patient with a markedly disproportionate, unruptured SVA.
