Contact Force Sensing Use in Atrial Fibrillation Ablation

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

There are multiple important factors which need to be monitored when conducting ablation for atrial fibrillation. The contact between the catheter tip and the inside of the heart wall is now measurable and may improve the effectiveness of catheter ablation for atrial fibrillation patients.

Condition Intervention
Atrial Fibrillation
Procedure: Ablation

Study Type: Interventional
Study Design: Allocation: Non-Randomized

Primary Outcome Measures:
  • Rate of Acute Pulmonary Vein Reconnection [ Time Frame: 1 hour post procedure ]

Estimated Enrollment: 40
Study Start Date: May 2012
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Contact Force Known
Ablation with contact force data known
Procedure: Ablation
Atrial Fibrillation Ablation with SmartTouch catheter
Experimental: Contact Force Not Known
Contact Force data unavailable during ablation
Procedure: Ablation
Atrial Fibrillation Ablation with SmartTouch catheter

Detailed Description:
This study compares patients who have this procedure where this contact information is known (unblinded) versus those where the contact information is not known (blinded). The outcome is the rate of acute reconnection at 1 hour after achieving pulmonary vein isolation.

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients with symptomatic AF

Exclusion Criteria:

  • Recent CVA
  • Contraindication to warfarin therapy
