Post-operative images. (A) Post-operative transthoracic echocardiographic image with color flow mapping from the parasternal long-axis vies in patient 1. The geometry of the aortic root reinforced by wrapping a Dacron graft (Arrowheads) is well restored and maintained as a bulging morphology. And well-coaptating aortic valve cusps with trivial aortic regurgitation are also noted. (B) Post-operative three-dimensional volume rendering of contrast-enhanced CT scans in patient 1. It reveals that the ascending aorta was replaced with a prosthetic graft and the aortic root was reinforced by wrapping a Dacron graft (asterisk). Also proximal and distal anastomotic lines (arrow) were visible.
