Approaches for Focal Impulse and Rotor Mapping in Complex Patients: A US Private Practice Perspective1
56 consecutive patients with a mean follow up of 7.7±3.0 months.
The majority of patients consisted of persistent AF (34%) or long-standing persistent AF (43%), large atria, and/or complex co-morbidities.
FIRM mapping revealed rotors/focal sources in all patients.
- 62.5% (35/56) of patients had right atrial rotors.
- Patients with enlarged atrial volumes or who have failed a previous AF ablation have a significantly higher number of right atrial rotors.
Finally, FIRM mapping was added without impacting the workflow of the AF ablation procedure, as evidenced by a total procedure time (221 min.) that is similar to findings reported in other studies.
