Abstract
Objective: Evaluate long-term results of autologous pericardial valved cond uits in the pulmonary outflow. Methods: Between June 1983 and October 1993, 82 conduits were placed in the outflow of the venous ventricle, Patients who received homografts (n = 2 p atients), heterografts (n = 3 patients), and valveless conduits (n = 19 pat ients) and those patients who died within 90 days after the operation were excluded. Fifty-four survivors of pulmonary outflow reconstruction with fre sh autologous pericardial valved conduits were followed up from 5 to 15 yea rs (mean, 7.47 +/- 2.8 years). Diagnosis include D-transposition of great a rteries (n = 16 patients), L-transposition of great arteries (n = 14 patien ts), tetralogy of Fallot, pulmonary atresia with ventricular septal defect (n = 11 patients), truncus arteriosus (n = 10 patients), and double-outlet ventricle (n = 3 patients). Implantation age ranged from 0.25 to 24 years ( mean, 5.2 +/- 4.2 years). Median conduit diameter was 16 mm. Two-dimensiona l echocardiographic Doppler evaluations were made yearly; 9 patients underw ent cardiac catheterization. Reintervention fur stenosis was indicated when the pressure gradient exceeded 50 mm Hg.
