Use of untreated fresh autologous pericardium for reconstruction of pulmonary valve in tetralogy of Fallot requiring transannular patch: Is it the best material?

Method Between December 2006 and 2012, 98 operated TOF were divided into four groups based on requirement of a monocusp, tricuspid repair of bicuspid PV or need of a tricuspid PV in patients requiring TAP. Group I, monocusp (n = 50), Group II, repaired bicuspid PV valve (n = 6), Group III tricuspid PV (n = 22) and group IV avoiding TAP (n = 20). FAP sutured to the undersurface of TAP and native annulus was used to create a new annulus and a competent PV with one of techniques. Efficiency was assessed by presence of regurgitation or gradient and leaflet thickening and motion by 3 D echocardiography imaging.
