A Computed tomographic (CT) image 14 years after aortic root replacement shows the LCA button aneurysm with a diameter of 10 mm. B CT image 24 years after aortic root replacement shows that the LCA button aneurysm gradually enlarged to a diameter of 20 mm. C Preoperative three-dimensional reconstructed CT image shows the LCA button aneurysm. D, E Postoperative CT image shows successful reconstruction of the LCA system.
