Aortic root reconstruction in two patients with chronic aortic dissection by aortic valve-sparing procedures using a new aortic root conduit with the sinuses of valsalva (De Paulis Valsalva graft).

The durability of the aortic valve after aortic root reconstruction by an aortic valve-sparing procedure is of particular concern because of the absence of the sinuses of Valsalva in the David type-I reimplantation method. Various improvements have been made to the David-I method. In particular, a new aortic root conduit with the sinuses of Valsalva was developed recently and is expected to improve the long-term follow-up results of the aortic valve-sparing procedures. We used a Valsalva graft in two patients with aortic root dilation accompanied by aortic regurgitation and obtained good short-term results.
