简要总结

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.

详细描述

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.
