Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators have conducted a prospective, double-blind, randomized study to assess the comparative safety and efficacy of two different ablation strategies, PVI plus linear lesions (LL) versus PVI plus GP ablation, in patients with persistent or longstanding persistent AF. Results were assessed after follow-up of at least 3 years with the use of an implanted monitoring device (IMD).

PVI+LL

Circumferential PVI was accomplished and then additional ablation lines were created by connecting the left inferior PV to the mitral annulus (mitral isthmus) and the LA between the two superior PVs (roof). Finally, patients underwent cavo-tricuspid isthmus ablation in the right atrium.

Intervention Type PROCEDURE

Linear Lesion Ablation

Intervention Type PROCEDURE

PVI+GP

To accomplish ganglionated plexi ablation, LA target sites were identified as the anatomic locations where vagal reflexes were evoked by transcatheter high-frequency stimulation (HFS). Rectangular electrical stimuli were delivered at a frequency of 20-50 Hz, output amplitude 15 V and pulse duration of 10 ms, for 5 sec (Stimulator B-53, Biotok Inc, Russia).
