This prospective randomized controlled trial evaluated the effects of a 3D electroanatomical mapping (3D-EAM) visualized steerable sheath versus a non-visualized sheath in 100 patients undergoing radiofrequency catheter ablation for atrial fibrillation. The study found that the Vizigo sheath significantly reduced fluoroscopy time (11.43 vs. 15.37 min, p = 0.0013) and improved first-pass pulmonary vein isolation success (84% vs. 64%, p = 0.023).
Key findings
- Fluoroscopy time was significantly lower in the Vizigo group (11.43 min) compared to the Agilis group (15.37 min, p = 0.0013).
- First-pass pulmonary vein isolation success was higher in the Vizigo group (84%) than in the Agilis group (64%, p = 0.023).
- AF-free survival at 12 months was 91.8% in the Vizigo group compared to 83.3% in the Agilis group (p = 0.203).
Why it matters
The findings suggest that using a 3D-EAM visualized steerable sheath can enhance procedural efficiency and potentially improve outcomes in atrial fibrillation ablation, which may influence clinical practice in catheter-based interventions.
