Arrhythmias & electrophysiologyCohort study
Acute and mid-term outcomes of ablation for atrial fibrillation with VISITAG SURPOINT: the Japan MIYABI registry
- Prospective observational registry study
- multicentre
- 50 Japanese centres
Authors' conclusion
Despite lower anterior wall VS values compared with the CLOSE protocol (≥550), the present study demonstrated comparable efficacy outcomes, indicating that a VS of ≥550 for the anterior wall may not be necessary for Asian patients.
