Non-fluoroscopic ablation of supraventricular tachycardia — results of a new approach

Le résumé fourni par la source

Objective. To evaluate the efficacy and safety of catheter ablation of supraventricular tachycardia (SVT) using exclusively intracardiac ultrasound compared to conventional fluoroscopic approach. Material and methods. There were 170 patients with SVT (85 patients in each group): 128 ones with atrioventricular nodal reentry tachycardia (AVNRT) and 42 ones with atrioventricular re-entry tachycardia (AVRT). In the non-fluoroscopic group, ablation was performed under intracardiac ultrasound guidance. The follow-up period was 12 months. Results. Intraoperative success rate was 100% in both groups. Freedom from recurrence was comparable among patients with AVNRT (90.6% vs. 93.75%, p=0.74) and AVRT (95.2% vs. 95.2%). Safety of procedures was also similar (AVNRT 4.7% vs. 0%, p=0.24; AVRT 0% vs. 0%). Fluoroscopy was used in none patient who underwent the procedure under intracardiac ultrasound guidance (p < 0.001). However, surgery time and overall RF-ablation time was significantly shorter in the non-fluoroscopic group among patients with AVNRT. Conclusion. Catheter ablation of SVT under intracardiac ultrasound control is possible without fluoroscopy and electrophysiological navigation. This procedure is effective and safe.
