Pacing of Left Bundle Branch Area and Atroventricular Node ablatIon in Patients With Symptomatic Atrial Fibrillation

RecruitingNA

Sponsor: Seoul National University Hospital

Conditions: Atrial Fibrillation (AF)

Interventions: Pacemaker implantation with Left bundle branch area pacing (LBBAP), Atrioventricular node ablation (AVNA), Pharmacologic therapy optimized for Atrial Fibrillation management

Countries: South Korea

This study aimed to compare the clinical outcomes of left bundle branch area pacing combined with atrioventricular node ablation and pharmacologic treatment optimized according to guidelines in patients with symptomatic atrial fibrillation refractory or intolerant to drug therapy or catheter ablation.
