Congenital: Aortic Valve
Neoaortic support hose
Dramatic neoaortic root dilation is well described after the Ross procedure, with z scores greater than 8 commonly seen.1 Reintervention to repair neoaortic root aneurysm for risk of rupture after the Ross procedure is uncommon and is seldom indicated, but reintervention for progressive neoaortic valve insufficiency is not uncommon and has been a reason for some institutions to lose enthusiasm for the Ross operation.Outcome after aortic valve replacement in children: A systematic review and meta-analysis
Despite an increasing interest in pediatric aortic valve repair, aortic valve replacement in children may be unavoidable. The evidence on outcome after pediatric aortic valve replacement is limited and usually reported in small case series. This systematic review and meta-analysis aims to provide an overview of reported outcome of pediatric patients after aortic valve replacement.A composite semiresorbable armoured scaffold stabilizes pulmonary autograft after the Ross operation: Mr Ross's dream fulfilled
Use of resorbable external reinforcement of the pulmonary autograft during the Ross operation has been suggested, but the differential regional potential for dilation of the aorta, mainly regarding the neo-root and the neo-Valsalva sinuses, represents an unresolved issue. Auxetic materials could be useful in preventing dilation given their favorable mechanical properties. We designed a composite semiresorbable armoured bioprosthesis constituted by polydioxanone and expanded polytetrafluoroethylene and evaluated its effectiveness as a pulmonary autograft reinforcement device in an animal model of the Ross procedure.
