Condition persistent atrial fibrillation
Treatments heartlight(tm) laser balloon, irrigated radiofrequency current ablation
Sponsor Boris Schmidt
Start date June 2013
End date September 2016
Trial size 152 participants
Trial identifier NCT01863472, FF20/13 Version 03


Aim of the study is to compare the safety and efficacy of pulmonary vein isolation using the endoscopic ablation system in comparison to irrigated radiofrequency current ablation in patients with drug-refractory persistent atrial fibrillation.
