[Methods and results of catheter electrodestruction in treating tachyarrhythmias].
Catheter electrodestruction (fulguration) was used in 56 patients with supraventricular and ventricular tachycardias resistant to conservative treatment. Its procedure and results are described. Transvenous electrodestruction of the His bundle and proximal portions of the atrioventricular junction was performed in 40 patients. Complete atrioventricular block and pacemaker implantation were used in 39 patients. In 3 cases with first- or second-degree atrioventricular block, tachycardiac paroxysms were absent in the presence of an antiarrhythmic therapy. In 1 case, tachyarrhythmia recurred after 6 months, so that repeated catheter electrodestruction of the His bundle was required. Radical surgery was performed in 16 patients: electrodestruction of atrial arrhythmogenic zones in 5, that of complementary atrioventricular junctions in 9, and that of left-ventricular arrhythmogenic zones in 2. The results were successful (tachyarrhythmias resistant to conservative treatment disappeared altogether at 6 months to 3.5 years follow-up) in 52 patients.
