Simple Modification of “T Simple Modification of “T. David-V” Valve-Sparing Aortic Root Replacement to Create Graft Pseudosinuses Philippe Demers, MD, D.Craig Miller, MD The Annals of Thoracic Surgery Volume 78, Issue 4, Pages 1479-1481 (October 2004) DOI: 10.1016/j.athoracsur.2003.08.032
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). The Annals of Thoracic Surgery 2004 78, 1479-1481DOI: (10.1016/j.athoracsur.2003.08.032)
Fig 2 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).
