The results of surgical procedures for termination of Wolff-Parkinson-White (WPW) Syndrom were assessed in 59 patients undergoing operation between January, 1980 and December, 1993. All cases of WPW were refractory to medical treatment and 14 of 58 patients had one or several syncopes, and 4 of them had to be reanimated. The surgical treatment of these patients was a dissection of an accessory atrioventricular pathway. 15 patients required additional heart operation. A total of 60 accessory pathways were diagnosed preoperatively, 64 were located intraoperatively. The reoperation rate was 3% (2 patients) due to persistent WPW. Incidence of total AV block after the operation was 7% (4 patients). In the late postoperative stage, 12 patients developed supraventricular tachycardias, but none of these cases required a surgical treatment. The actuarial survival rate after 10 years was 100% and after 14 years 96%. We conclude that surgical dissection of accessory pathways offers a good alternative in cases of unsuccessful catheter ablative procedure or in cases of additional heart operation.
