Reconstruction of trileaflet pulmonary valve using autologous pericardium.

Tetralogy of Fallot with atretic or absent pulmonary valve may require pulmonary valve replacement or reconstruction. We propose a technique of reconstruction of a trileaflet valve at the level of the pulmonary annulus using untreated autologous pericardium. Six cases operated upon, using this technique, had trivial pulmonary regurgitation with a median gradient of 24 mmHg (18-38) across the newly created valve. This approach can be considered in cases with limited availability of more suitable alternatives.
