[Endocavitary electrocautery of a right anterior bundle of Kent]

The authors report another case of successful endocavitary electrocautery in a young woman with Wolff-Parkinson-White syndrome. The pre-excitation was controlled by the administration of two 250 joule electrical shocks applied to the atrial origin of the right anterior bundle. The clinical and laboratory tolerance were satisfactory. Although these results are encouraging, other studies are required in order to define the indications and protocols of electrocautery of accessory pathways.
