Background:
Right atrial electroanatomical mapping may be combined with SoundStar 3D diagnostic ultrasound catheter (EAM-ICE) as a zero-fluoroscopy procedure for radiofrequency catheter ablation (RFCA). We aimed to evaluate the efficiency and safety of zero-fluoroscopy transseptal puncture guided by EAM-ICE and fluoroscopy combined with intracardiac echocardiography (F-ICE) in patients with paroxysmal atrial fibrillation (PAF).
Hypothesis:
Zero-fluoroscopy transseptal puncture is an effective and safe procedure.
Methods:
This study had a prospective design. A total of 57 patients with PAF were enrolled and assigned to two groups. Twenty-seven patients were enrolled in the EAM-ICE group, and 30 patients were enrolled in the F-ICE group.
Results:
There were no statistically significant differences in baseline patient characteristics between groups. Transseptal puncture was successful in all patients (57/57, 100%). Total procedure time and duration of transseptal puncture were lower in the F-ICE group (199.4 ± 26.0 minutes vs 150.7 ± 22.1 minutes, P = 0.000; 118.4 ± 19.7 vs 70.5 ± 13.5 minutes, P = 0.000). There was no use of fluoroscopy in the EAM-ICE group (0 mGy vs 70.5 ± 13.5 mGy); the duration of fluoroscopy in the EAM-ICE group was negligible (0 minutes vs 5.4 ± 1.9 minutes). No procedural complication occurred in either group.
Conclusions:
EAM-ICE guided zero-fluoroscopy transseptal puncture is an effective and safe procedure.
