Summary
The WIDER PVI study is a multicentre randomized clinical trial to compare the efficacy of antral versus extended antral PVI in patients with paroxysmal or persistent AF undergoing this procedure using a cryoablation balloon capable of 28 mm diameter (antral isolation) or 31 mm diameter (extended antral isolation) applications. The aim is to evaluate an objective of superiority of the extended antral isolation strategy versus antral isolation in the recurrence of atrial tachyarrhythmias at 1-year follow-up, both in episodes of \>30 seconds duration and in overall arrhythmic load.
