Brief summary

To compare the safety and chronic Pulmonary Vein isolation of 2 ablation types. 1. visually guided ablation (VGA) using the EAS-AC and 2. radiofrequency ablation

Detailed description

The goal of the study was to compare two interventions, visually-guided endoscopic ablation to standard-of-care radiofrequency (RF) ablation. The study was terminated early by the Sponsor for business reasons before any participants were randomized or treated with RF ablation.

Outcome results

Primary

Rate of Permanent Pulmonary Vein Isolation of EAS-AC Compared to EAM Guided Radiofrequency Ablation

Number of initially isolated pulmonary veins that remain isolated at a 3 month remapping. The unit of measure is treated pulmonary veins (PVs).

Time frame: 3 Months

Population: Of the 21 enrolled participants, 19 were treated participants and 17 of the 19 came back for the 3 month PV remapping and were thus evaluable for effectiveness. This resulted in 46/59 (78%) pulmonary veins being assessed for chronic isolation.
