Benefit of Left Atrial Roof Ablation in Paroxysmal Atrial Fibrillation

December 11, 2013 updated by: Josep Lluis Mont Girbau, Hospital Clinic of Barcelona
The aim of the present study is to assess whether left atrial roof ablation adds any benefit in the arrhythmia-free probability after paroxysmal atrial fibrillation ablation.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Conventional ablation
Pulmonary vein encircling by performing continuous radiofrequency lesions surrounding each ipsilateral pulmonary vein antrum
Procedure: Pulmonary vein encircling
Pulmonary vein encircling by performing continuous radiofrequency lesions surrounding each ipsilateral pulmonary vein antrum
Active Comparator: Conventional ablation plus left atrial roof ablation
Pulmonary vein encircling by performing continuous radiofrequency lesions surrounding each ipsilateral pulmonary vein antrum plus creation of a radiofrequency line joining contralateral superior pulmonary veins throughout the left atrial roof.
