Abstract:
Although the “near‐zero‐X‐Ray” or “No‐X‐Ray” catheter ablation (CA) approach has been reported for treatment of various arrhythmias, few prospective studies have strictly used “No‐X‐Ray,” simplified 2‐catheter approaches for CA in patients with supraventricular tachycardia (SVT). We assessed the feasibility of a minimally invasive, nonfluoroscopic (MINI) CA approach in such patients. Methods Data were obtained from a prospective multicenter CA registry of patients with regular SVTs. After femoral access, 2 catheters were used to create simple, 3D electroanatomic maps and to perform electrophysiologic studies. Medical staff did not use lead aprons after the first 10 MINI CA cases. Results A total of 188 patients (age, 45 ± 21 years; 17% 〈 19 years; 55% women) referred for the No‐X‐Ray approach were included. They were compared to 714 consecutive patients referred for a simplified approach using X‐rays (age, 52 ± 18 years; 7% 〈 19 years; 55% women). There were 9 protocol exceptions that necessitated the use of X‐rays. Ultimately, 179/188 patients underwent the procedure without fluoroscopy, with an acute success rate of 98%. The procedure times (63 ± 26 vs. 63 ± 29 minutes, P 〉 0.05), major complications (0% vs. 0%, P 〉 0.05) and acute (98% vs. 98%, P 〉 0.05) and long‐term (93% vs. 94%, P 〉 0.05) success rates were similar in the “No‐X‐Ray” and control groups. Conclusions Implementation of a strict “No‐X‐Ray, simplified 2‐catheter” CA approach is safe and effective in majority of the patients with SVT. This modified approach for SVTs should be prospectively validated in a multicenter study.
