摘要
TC-RF （transcatheter radiofrequency） ablation has an important role in the treatment ofSVA （supraventricular arrhythmias）. The indication to TC-RF ablation is usually made to improve the patient＇s quality of life through the elimination of the arrhythmic substrate. The objective of this study is to make a brief review of the literature and to report the Electrophysiology Unit experience of the Cardiovascular Department of the University Hospital of Trieste. From the study, it can be found that about one thousand of patients are visited annually in the Cardiovascular Department of the University Hospital of Trieste （1,019 ± 71/year over the past five years）. The acute success rate of atrial fibrillation and flutter ablation procedures was respectively 93.9% and 97.9% with a relapse rate of 30% and 10% at 12 month. Accessory pathways and nodal atrio ventricular re-entry tachycardia ablation procedures had an acute success rate of respectively 91.1% and 96.6% with a relapse rate of 10% at 12 months. The overall complication rate was 5%. Catheter ablation is an effective therapy for SVA treatment. It can often be definitive, and it is generally superior to drug therapy, with a low complication rate. The improvement in patients＇ quality of life is associated with a reduced need for access to health services.
