N/A Objectives : Among the current therapeutic options for paroxysmal supraventricular tachycardias, only surgery and ablative techniques are curative. However, surgery is associated with substantial cost, morbidity, and rarely death. Recently, catheter ablation techniques have been developed to treat paroxysmal supraventricular tachycardias. These techniques are effective and low-risk curative treatment for supraventricular tachycardias. This article shall describe our clinical experiences in radiofrequency catheter ablation for supraventricular tachycardias and review the literature. Methods: The study population consisted of 154 patients with supraventricular tachycardias from January 1993 to August 1995. Eighty one patients were men and seventy three patients were women, and their mean age was 41.29±15.41 years. Radio-frequency currents(mean) were applied through a catheter electrode positioned against the mitral or tricuspid annulus or a branch of the coronary sinus or atrioventricular node. Results: Among 154 patients, the mechanisms for paroxysmal supraventricular tachycardias were found to be atrioventricular reentrant tachycardia involving a concealed accessory pathway in 51(33.1%), Wolff-Parkinson-White syndrome in 57(37%), and atrioventricular nodal reentrant tachycardia in 46 (29.9%). Successful outcomes were achieved in 46 of 46 patients(100%) with atrioventricular nodal reentrant tachycardia, 7 of 8 patients(87.5%) with double accessory pathways, 69 of 72 patients(95.8%) with left-sided accessory pathway, and 19 of 28 patients (67.9%) with right-sided accessory pathway. Total 141 of 154 patients(91.6%) with supraventricular had a successful outcome with radio- frequency current application(mean). Conclusions: Radiofrequency catheter ablation techniques are highly effective in ablating accessory pathways or modifying atrioventricular node, with low morbidity and no mortality.
