Randomised Prospective Trial Comparing Contact Force and Non-contact Force Guided Catheter Ablation for Cavotricuspid Isthmus Dependent Atrial Flutter

Randomised Prospective Trial Comparing Contact Force and Non-contact Force Guided Catheter Ablation for Cavotricuspid Isthmus Dependent Atrial Flutter

Radiofrequency ablation (RFA) is a standard treatment option for cavotricuspid isthmus (CTI) dependent atrial flutter. We plan to perform a randomized prospective trial comparing the efficacy of contact force (CF) guided CTI ablation against catheter ablation with the operator blinded to contact force parameters.

Subjects will be followed for one year post procedure in order to check for atrial flutter recurrences. This will involve an in-person visit at 3 months post procedure, and records checks at 12 months post procedure.

Inclusion Criteria:

• Adult patients (over the age of 18) with 12 lead ECG documented paroxysmal or persistent CTI dependent atrial flutter planned to undergo CTI ablation.
• Able and willing to give informed consent.

Exclusion Criteria:

• Previous CTI ablation
• Previous non-CTI dependent atrial flutter (ie.patients with previous history of pulmonary vein isolation or left atrial ablation, congenital heart disease, surgical ablation)
