[Surgical treatment of Wolff-Parkinson-White syndrome]

The results of surgical treatment of 365 patients with the WPW syndrome are analysed. They underwent operation at the surgical department of the Kanazawa University Medical School in the period between 1973 and 1989. In 1969 T. Iva suggested an endocardial approach from the direction of the atrium for removal of the additional pathways, which the authors use at present also. The anomalies were congenital in 47 and acquired in 12 patients and were corrected in one stage during removal of the additional pathways. Multiple additional pathways were found in 33 patients. The additional pathways were completely removed in 33 patients. Paroxysms of tachycardia do not occur after the operation in 364 patients among the 365 who were operated on.
