The search for the ideal substitute for the diseased aortic valve led Donald Ross to develop the concept of the aortic allograft in 1962 and the pulmonary autograft in 1967 for subcoronary implantation, and later, in 1972, as a full root for replacing the aortic root in the infected aortic valve with a root abscess. The aortic allograft and pulmonary autograft surgical procedures were revolutionary in the history of cardiac valve surgery in the last millennium because they compete well with the bioprosthesis, are nonthrombogenic (thus, requiring no postop
