Trial outcomes

Primary outcomes

1

Acute Success of the Left Atrial Posterior Wall Ablation

After the last application of PE energy, and after a 20-minute wait, all lesions will be verified by careful 3D-electro-anatomical mapping (voltage and activation mapping) and by conventional pacing manoeuvres.
