RECONSTRUCTION OF THE RIGHT VENTRICULAR OUTFLOW TRACT WITH A POSTERIOR MONOCUSP VALVE.

Reconstruction of the right ventricular outflow tract with sections of pericardium or with Dacron patches often leads to pulmonary regurgitation. This report presents a technique for minimizing regurgitation by creating a single posterior leaflet using the patient's own valve. After incision of the pulmonary artery and valvular ring, the valve is brought forward to cover the opening of the reconstructed pulmonary artery. This time-saving technique avoids the risk of calcification which usually accompanies the use of homografts and heterografts.
