[Radiofrequency ablation of left-sided atrioventricular accessory tract to treat supraventricular tachycardia].
Eleven procedures of radiofrequency catheter ablation of left-sided atrioventricular accessory tract were performed in 10 patients with atrioventricular reentry tachycardia aged 13-57 (32.7 +/- 13.2) years old. 10 patients, 9 with overt preexcitation syndrome and 1 with concealed bypath tract, had paroxysmal supraventricular tachycardia refractory to drugs for 1-31 (7.8 +/- 9.8) years. The ablation was succeeded in 9 cases (90%). The accurate localization of the accessory tract and the operating skill of ablation electrode were the key factors of success in ablation and reducing exposure to x-ray.
