Extracardiac conduits in right Side of the heart for complex congenital heart anomalies invariably need to be replaced due to growth of the patient or conduit failure. Allograft conduits seem the best choice but they are scarce. We used stentless porcine bioprosthesis (Medtronic Freestyle in 19; Cryo-Life Ross in 3 and Baxter-Edwards Prima in 3) as an extracardiac conduit for right side of the heart on 25 patients. The hospital mortality was 8 % (n=2 patients). Echocardiographic evaluations of all patients before hospital discharge demonstrated no more than 18 mmHg pressure gradient across the conduit. The median follow-up was 16,4 +/- 11,2 months (range 1 to 45 months). Three patients died at 6, 12 and 30 months follow-up. Conduit failure developed in 1 patient who had Baxter-Edwards Prima bioprosthesis at postoperative sixth month. Unrestricted life style was possible for 85 % (n=17 patients) of survivors. In conclusion, porcine stentless bioprosthesis may be an alternative for right side reconstruction of complex congenital cardiac anomalies. Evaluation of long - term results with large series are necessary.
