2. Fig 1
Intraoperative picture illustrating a completed valve-sparing aortic root replacement with the modified Tirone David-V technique with a 34-mm graft used proximally (black arrow) and a 24-mm graft distally (white arrow). Note the large proximal graft surrounding the valve and how well the smaller distal graft conforms to the small (normal-sized) distal ascending aorta. The right coronary artery button is visible in the right graft pseudosinus (white arrowhead).

Postoperative transthoracic echocardiogram (parasternal long-axis view in early diastole) demonstrating bulging graft pseudosinuses (arrowheads) in the reconstructed aortic root, a normal aortic annular diameter, well-coapting aortic valve cusps, and abrupt graft narrowing at the anastomosis between the proximal and distal grafts, representing the neosinotubular junction (arrows).
