Unusual right ventricle outflow tract obstruction in Dacron valved conduits

Abstract

Various biological valved conduits have been used to treat the obstructions of the right ventricle. These conduits have different rates and etiologies for conduit stenosis during early- and long-term follow-up. We report on three cases of unusual intra-luminal peeling of a Dacron conduit leading to various types of conduit obstruction.
