Objective — to analyze the risk of redo surgery and causes of xenograft failure in children after right ventricular outflow tract (RVOT) repair with valved conduit. Material and methods. A retrospective analysis included patients under 18 years old who underwent RVOT repair with xenograft in 2000—2017. Results. Three hundreds and thirty-three patients underwent implantation of 373 xenografts including glutaraldehyde-crosslinked bovine jugular vein (GA-JV) (n=200, 53.6%), glutaraldehyde-crosslinked bovine pericardial valved conduit (GA-PC) (n=77, 20.6%), diepoxy-crosslinked porcine aortic root conduit (DE-AR) (n=58, 15.5%) and diepoxy-crosslinked bovine pericardial valved conduit (DE-PC) (n=38, 10.2%). The median follow-up was 4.2 years (range 2 month — 14.5 years). Multivariate regression analysis did not reveal significant correlation of redo surgery and type of xenograft (p=0.65). However, type of xenograft was significant risk factor for redo surgery due to xenograft calcification (p=0.007) and neointimal hyperplasia (p=0.01). DE-AR group had 3 times higher risk of calcification than GA-JV group (p<0.001). Risk of calcification in GA-PC and DE-PC groups was comparable with GA-JV group (p=0.24 and p=0.53, respectively). GA-PC group had significantly higher risk of neointimal proliferation and subsequent redo surgery in comparison with DE-PC group (p=0.006). Conclusion. Freedom from redo surgery did not differ between groups regardless type of xenograft. However, the causes of conduit failure were different. DE-PC conduits failed mostly due to calcification, while GA-treated xenografts failed due to obstruction as the result of neointimal hyperplasia.
