Cavotricuspid isthmus ablation with a focal dual-energy catheter: First commercial experience
Typical cavotricuspid isthmus (CTI) atrial flutter (AFL) frequently coexists with atrial fibrillation (AF). 20%–25% of patients with AF will also have documented typical AFL, and many treated for isolated AFL later develop AF.1 Thus, in patients with atrial arrhythmias, both pulmonary vein isolation (PVI) and CTI block may be required to achieve long-term freedom. Pulsed-field ablation (PFA) has become the preferred ablation modality for PVI, but its role in CTI remains limited.2,3 Currently, operators using PFA systems often switch to radiofrequency (RF) catheters for linear lesions such as the CTI line, adding time, cost, and complexity.
