Between March 1986 – May 1991 nonvalved conduits were used in 10 patients, ages raging between five and seventeen years. Caridac pathologies were atrioventricular and ventriculoarterial discordance (Cor. TGA) with ventricular septal defects (VSD) and pulmonary stenosus (PS) in 5, transposition of great arteries (TGA) + VSD +PS in 1, double outlet right ventricle (DORV) with great arterial malposition + VSD + PS in 1, and double outlet left ventricul (DOLV7 + VSD + PS in 3. pulmonary obstruction was valvular in 1, valvular and infundibular in 7. There were two patients with pulmonary atresia.

Valveless conduits 16-28 mm in diameter were used between the pulmonic ventricle and the pulmonary artery. All patients recovered from operation and remained well, except one with DOLV who died with severe arrythmaias on the 3rd postoperative day. During the mean follow-up of 41.12 ± 13.8 months one patients died of acute cardiac failure due to endocarditis and sepsis in the ninth month and all other patients were asymptomatic without needing reoperation.

These results have been encouraging for the use of nonvaled conduits in complex congenital cardiac anormalies with low pulmonary vascular resistance.
