Abstract

Background: Development of electroanatomical systems make it possible to perform ablations without the use of fluoroscopy. The aim of this study was to evaluate the efficacy and safety of cryoablation pro­cedures without the use of fluoroscopy.

Methods: The study group consisted of 45 patients (14 female; age 36 ± 15 years) treated with cry­oablation using the EnSite electroanatomical system: 10 with ventricular extrasystoly from the right ventricle, 6 with the arrhythmogenic site near the left coronary artery, 17 patients with Wolff-Parkinson- -White syndrome (WPW), 2 patients with atrioventricular nodal reentrant tachycardia (AVNRT) type 2, 7 patients with AVNRT type 1, 3 patients with atrial tachycardia.

Results: In 38 of the 45 patients (84%) cryoablation procedure was performed without the use of fluoroscopy. Cryoablation efficacy was 78.9%. In 5 patients unsuccessful cryoablation was fallowed by radiofrequency applications. Finally, efficacy reached 92.1%. There were no deaths. In 1 patient a small adverse event — right bundle branch block was observed after ablation of para-Hisian accessory path­way. No other adverse events were observed. In the long term follow-up efficacy was 89.5%.

Conclusions: Cryoablation using electroanatomical system without the use of fluoroscopy is a safe and efficient procedure and it is a possible alternative in most patients qualified for cryoablation.
