LSI (Lesion Index) Workflow Observational Study

Status Completed

Clinical Trial Summary

This clinical study is a prospective, multicenter, post-market, single-arm, observational study designed to characterize the usage of the Lesion Index (LSI) with the market-released TactiCath Contact Force Ablation Catheter, Sensor Enabled (TactiCath SE) in subjects with Paroxysmal Atrial Fibrillation (PAF) in a real-word environment.

Clinical Trial Description

The primary objective of this study is to characterize LSI achieved values for durable lesion formation using the TactiCath SE catheter in the different anatomical regions around the pulmonary veins (PVs) of the heart during RF ablation for the treatment of drug-refractory paroxysmal atrial fibrillation (PAF) Secondary objectives of this study are as follows: - To characterize the use of EnSite Automap and AutoMark module software settings, including LSI threshold (OUS), contact force, time, power, flow, and AutoMark spacing using the TactiCath SE catheter for RF ablation for the treatment of drug-refractory PAF. - To characterize LSI achieved values for lesions that reconnected versus those that were durable, both in an acute procedural setting as well as in patients who undergo additional ablations during the 12-month follow-up period after an index RF ablation procedure for the treatment of drug-refractory PAF. ;
