Background: The majority of EP's who perform PVI procedures for patients who have symptomatic atrial fibrillation rely heavily on fluoroscopy despite having multiple visualization modalities at their disposal including 3-D mapping techniques, intra-cardiac ultrasound, and remote magnetic navigation systems.
Methods: The study is composed of 72 consecutive patients undergoing PVI for symptomatic drug refractory paroxysmal and persistent atrial fibrillation (AF) from August 1, 2015 to August 1 2016. 52 patients who underwent traditional PVI (30 with radiofrequency and 22 with cryoablation) with fluoroscopy were compared to 20 patients who underwent RF PVI with NO fluoroscopy. All patients who underwent RF PVI utilized the CARTO 3-D mapping system with a contact force sensing catheter. All transseptal access was achieved with intra cardiac ultrasound (ICE).
Results: More patients in the NO fluoroscopy group had CAD otherwise there were no significant differences in a number of clinical variables. Overall, procedure time was less in the NO fluoroscopy group despite similar ablation times. There was no significant difference in complication rates including: vascular complications, tamponade, stroke and death.
Conclusions: Atrial fibrillation ablation with PVI using RF with NO fluoroscopy in a new operator is feasible and safe with 3-D electroanatomic mapping in conjunction with contact force sensing catheters.
