Objective: We sought to determine, by a mathematical model, the ideal theoretical degree of ascending aortic graft oversizing needed to obtain normal sinuses dimension in the reimplantation type of valve-sparing aortic operations. Methods: To define a normal-range value, size of sinuses of Valsalva...
