Contact Force Sensing Use in Atrial Fibrillation Ablation

The Role of Contact Force Sensing in Electrical Pulmonary Vein Isolation When Conducting Atrial Fibrillation Ablation

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.

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.

Inclusion Criteria:

• Patients with symptomatic AF

Exclusion Criteria:

• Recent CVA
