Pulmonary valve preservation and restoration strategies for repair of tetralogy of Fallot

Abstract

AbstractDespite tremendous advances in surgical treatment of tetralogy of Fallot, augmenting the small right ventricular outflow tract remains a challenge. Transannular patch augmentation revolutionised surgical management, but did so at the expense of rendering patients with pulmonary insufficiency and the resulting problems associated therewith. Recent surgical efforts have focused on pulmonary valve preservation at initial correction and pulmonary valve restoration after transannular patching, with favourable results. In this manuscript, we review methods of pulmonary valve preservation and restoration.
