ABSTRACT
The use of a transannular patch for right ventricular outflow tract reconstruction in patients with inadequate pulmonary annulus has shown immediate changes in haemodynamics, changing from a pressure-loaded to a volume-loaded right ventricle, due to the pulmonary regurgitation that generally occurs. Several methods have been used to abolish or decrease pulmonary insufficiency.1-4 The use of monocusp grafts for right ventricular outflow tract reconstruction remains controversial. The purpose of this chapter is to present results using a porcine monocusp graft, which has been employed at the authors’ institution during the last seven years.
