A neoaortic aneurysm after a Norwood type reconstruction of the aorta can develop due to systemic pressure on the former pulmonary artery wall. A complex valve sparing procedure can preserve native valves and avoid a valve replacement with requirement for anticoagulation. This type of operation was carried out in 3 patients, 2 of them after a Fontan palliation, 1 after a Norwood-Rastelli repair. The reconstruction was done using Dacron prostheses for the replacement of the dilated wall, similar to a Yacoub modification in 2 cases and to a David's modification in 1 patient. The postoperative course was uneventful and postoperative valve function was good in all cases.
