Study design
A retrospective analysis was performed on thirty consecutive RFA procedures conducted at a single center by a single operator (DPS) between February and June 2019. Patients with history of previous ablation or cardiac surgery, as well as cardiac implants, were excluded from the series. Fifteen consecutive patients undergoing PVI procedures using the Agilis™ NxT Steerable Introducer (Abbott, WS, USA) were compared to 15 consecutive patients using the SureFlex™ Steerable Guiding Sheath (Baylis Medical, Montreal, CA). Standard informed consent was obtained prior to each procedure. Institutional approval was obtained for retrospective chart review.
