Simple modification of "T. David-V" valve-sparing aortic root replacement to create graft pseudosinuses.
The absence of sinuses of Valsalva is postulated to perturb coronary flow patterns and to create abnormal leaflet stresses, which theoretically may limit the long-term durability of valve-sparing aortic root replacement with the original Tirone David-I reimplantation technique with a cylindrical tube graft. David developed the "T. David-V" procedure in 2001; it creates large billowing Dacron pseudosinuses while retaining the reimplantation concept. To illustrate a simple modification of the T. David-V technique, we describe a patient with Marfan's syndrome who underwent valve-sparing aortic root replacement with 1 large and 1 small graft to create pseudosinuses in the Dacron graft, to facilitate suturing the valve inside the graft, and to make the distal graft-to-aorta anastomosis a better size match.
