Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Patients with persistent irregular heartbeats also called persistent atrial fibrillation usually have a lower probability of curing their arrhythmia with ablation with heat called radiofrequency then those with paroxysmal atrial fibrillation, as previous studies have shown. The emerging ablation with freeze(cryoablation) has not been studied for persistent atrial fibrillation but has been proven to be efficient in the paroxysmal type. We hypothesized that persistent atrial fibrillation will have a freedom of recurrence rate of 70% after use of cryoablation at one year of follow up.
