TactiCath® Contact Force Ablation Catheter Study for Atrial Fibrillation Post Approval Study (TactiCathPAS)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02310100

Brief Summary:
A prospective, multicenter, interventional study to collect confirmatory evidence on the safety and effectiveness of the TactiCath® percutaneous ablation catheter in the post approval setting for the treatment of symptomatic paroxysmal atrial fibrillation using contact force assisted irrigated radiofrequency ablation.

Condition or disease Intervention/treatment Phase
Paroxysmal Atrial Fibrillation Device: TactiCath Quartz treatment Not Applicable

Detailed Description:

The TactiCath Quartz PAS is a prospective, non-randomized, multicenter, interventional study to evaluate the continued safety and effectiveness of the TactiCath Quartz Set for the treatment of symptomatic paroxysmal atrial fibrillation (PAF) using contact force assisted irrigated RF ablation.

Patients undergoing elective catheter ablation for symptomatic PAF who are refractory or intolerant to at least one antiarrhythmic drug (Class I-IV) will be screened for enrollment. Patients who meet the study entry criteria and sign the patient informed consent form will be enrolled and treated following the standard of care at each study site.

After the index procedure, subjects will be followed for a total of 60 months. During the 3-month blanking period following ablation, subjects may undergo up to 2 repeat ablation procedures (up to 10 days prior to end of the blanking period) using the same device used during ablation. Subjects will be evaluated at pre-discharge, at 7 days, at 3, 6 and 12 months post-index procedure and then yearly thereafter. Subjects will complete Holter monitoring at 3- and 6- months post index ablation procedure and at yearly intervals beginning at 12 months post-index ablation procedure.

Primary Outcome Measures :
  1. Number of Participants Free From Recurrent, Symptomatic Paroxysmal Atrial Fibrillation (PAF), Atrial Flutter (AFL), and Atrial Tachycardia (AT) [ Time Frame: 12 Months post ablation ]
    Rate of subjects free from symptomatic Paroxysmal Atrial Fibrillation (PAF), Atrial Flutter (AFL), and Atrial Tachycardia (AT) lasting longer than 30 seconds through 9 months of follow-up after a 3 month blanking period compared to a stated performance goal. Procedural failure defined by any of the following events: (1) Documented recurrence of AF/AFL/AT during the 9-month observational period lasting longer than 30 seconds; (2) Repeat ablation following the blanking period; or (3) Use of s new anti-arrhythmic drug for the documented symptomatic atrial arrhythmia following the blanking period.

  2. Number of Participants Experiencing a Device or Procedure-related Serious Adverse Event [ Time Frame: 7 days ]
    The rate of device or procedure serious adverse events occurring within 7 days of the index procedure or hospital discharge, whichever is later, compared to a stated performance goal.
