Trial Outcomes & Findings for TactiCath Contact Force Ablation Catheter Study for Atrial Fibrillation (NCT NCT01278953)
NCT ID: NCT01278953
Last Updated: 2019-02-21
Results Overview
Includes both acute success (successful electrical isolation of all pulmonary veins) and chronic success. Re-treatment for AF with ablation or the use of Class I or Class III antiarrhythmic drugs after a 3 month blanking period constitute a treatment failure.

PRIMARY outcome
Timeframe: 12 monthsPopulation: Primary effectiveness was calculated using the Per Protocol (PP) population (n=280). 10 subjects who had PVI attempted were excluded from the PP population.due to insufficient data. A medical panel (DSMB) blinded to treatment, adjudicated the exclusion of subjects from the analysis (n=3 from TactiCath; n=7 from Control)
Includes both acute success (successful electrical isolation of all pulmonary veins) and chronic success. Re-treatment for AF with ablation or the use of Class I or Class III antiarrhythmic drugs after a 3 month blanking period constitute a treatment failure.
