Key result
The Achieve Advance mapping catheter significantly increased the visualization rate of real-time pulmonary vein recordings compared to the previous Achieve catheter (73.5% vs 56.8%, p=0.0001) during cryoballoon ablation.
Why the study?
The new Achieve Advance mapping catheter includes a solid core designed to improve rotational response, but its rate of real-time pulmonary vein potential recording visualization compared with the previous catheter was unknown.
Does the new Achieve Advance mapping catheter improve the rate of visualisation of real-time recordings compared to the previous Achieve catheter during cryoballoon ablation of atrial fibrillation?

Absolute Event Rate: 73.5% vs 56.8%
p-value: p=0.0001
The new Achieve Advance mapping catheter significantly improves the visualization of real-time pulmonary vein potentials during cryoballoon ablation compared to the previous generation.
Mugnai et al. (2019) conducted a cohort in Atrial fibrillation (n=200). Achieve Advance inner lumen mapping catheter vs. Previous Achieve mapping catheter was evaluated on Visualization of real-time recordings of pulmonary vein potentials (p=0.0001). The Achieve Advance mapping catheter significantly increased the visualization rate of real-time pulmonary vein recordings compared to the previous Achieve catheter (73.5% vs 56.8%, p=0.0001) during cryoballoon ablation.
