The Ross-Yacoub procedure for aneurysmal autograft roots: A strategy to preserve autologous pulmonary valves

Root reoperation with pulmonary valve preservation is feasible in the majority of patients with autograft aneurysms, allowing for maintenance of normal quality of life. Referral of patients with a dilated root before the appearance of severe valve insufficiency increases the likelihood of pulmonary valve sparing. Functional behavior of remodeled autograft roots is rewarding; however, continued observation is warranted.
