Outcomes of Atrioventricular Node Ablation and Pacing in Patients with Heart Failure and Atrial Fibrillation: From Cardiac Resynchronization Therapy to His Bundle Pacing

Objective: To review the relevant literature on use of atrioventricular node ablation and pacing in patients with heart failure atrial fibrillation. Methods: APubMed/MEDLINE SCOPUS search was performed order to assess clinical outcomes pacemaker implantation, as well complications that may occur. Results: Several trials, observational analyses meta-analyses have shown “pace ablate” strategy not only improves symptoms but also can enhance cardiac performance Although this procedure is effective safe, some occur including worsening failure, permanent fibrillation, arrhythmias sudden death. Regarding resynchronization therapy be optimal choice compared right ventricle apical pacing. His bundle a promising alternative has beneficial effects, while left branch an innovative modality. Conclusions: Atrioventricular implantation effects fibrillation ± who do respond or are intolerant medical treatment. Cardiac treatment seems way these patients.
