Atrioventricular Node Ablation in Patients With Atrial Fibrillation and Moderate Chronic Heart Failure (VISTA)

June 5, 2018 updated by: Federal State Budgetary Institution, V. A. Almazov Federal North-West Medical Research Centre, of the Ministry of Health

Variant of Stimulation in Atrioventricular Node Ablation (VISTA) in Patients With Atrial Fibrillation and Moderate Chronic Heart Failure

The purpose of this study is to determine whether cardiac resynchronization therapy (CRT) is superior to interventricular right ventricle (RV) septal pacing in respect of reverse remodeling (LV ESD) and morbidity in patients with less preserved (less than 45%) ejection fraction (EF), persistent/permanent atrial fibrillation (AF) who successfully received atrioventricular (AV) junction ablation ablation (100% pacemaker dependency)
