Outcome and performance of bioprosthetic pulmonary valve replacement in patients with congenital heart disease

This single center review assessed the need for reintervention after pulmonary valve replacement with bioprostheses for congenital heart disease.  Most patients had TOF, and most were in their teens or twenties.  After correction for age, the Sorin Mitroflow valve required reintervention sooner and more often than the other two valves (Carpentier-Edwards Magna and MagnaEase, Carpentier-Edwards Perimount).  Valve type was the only independent predictor of reintervention.
