Long Term Follow-Up After Atrioventricular Node Ablation and Right Ventricular Pacing: Effects on Clinical Events and Left Ventricular Function
Among rate control strategies for atrial fibrillation is atrioventricular junction ablation with ventricular pacing. Concerns about the long term safety of this procedure emerge as studies report deleterious effects of right ventricular pacing. A cohort of patients having undergone atrioventricular node ablation and right ventricular pacing was retrospectively studied. After 5 years of follow-u...
متن کاملDeterioration of left ventricular function following atrio-ventricular node ablation and right ventricular apical pacing in patients with permanent atrial fibrillation.
AIMS Transcatheter radiofrequency ablation of the atrio-ventricular (AV) node followed by ventricular pacing has been shown to improve symptoms and quality of life of patients with atrial fibrillation (AF). It is assumed that function improves, but this has been less well demonstrated. The aim of this study was to assess the long-term effect of AV node ablation and ventricular pacing on left ve...
متن کاملLeft ventricular mechanics during right ventricular apical or left ventricular-based pacing in patients with chronic atrial fibrillation after atrioventricular junction ablation.
OBJECTIVES The aim of the study was to evaluate whether left ventricular (LV) mechanics are better under LV-based pacing than under right ventricular (RV) apical pacing in patients with permanent atrial fibrillation (AF) after atrioventricular junction (AVJ) ablation. BACKGROUND "Ablate and pace" is an acceptable therapy for drug-refractory AF. However, the RV apical stimulation commonly used...
متن کاملVentricular pacing vs dual chamber pacing in patients with persistent atrial fibrillation after atrioventricular node ablation: open randomized study.
AIM To compare ventricular rate responsive (VVIR) pacing with dual chamber rate responsive (DDDR) pacing and antiarrhythmic drugs for the treatment of patients with persistent atrial fibrillation after atrioventricular node ablation. METHODS One hundred two patients with persistent atrial fibrillation eligible for the atrioventricular node ablation were randomly assigned to the therapy with e...
متن کامل[Ventricular pacing after atrioventricular node ablation].
We have read with interest the article by Dr. Moriña et al1 describing their initial experience with implantation of active fixation electrodes in the His bundle for permanent ventricular stimulation following ablation of the AV node. Their results are interesting as they establish stimulation threshold parameters and stable echocardiography measures after only a few months followup. Neverthele...
