Mechanisms of pacing interventions in atrial fibrillation.

abstract：INTRODUCTION:Data on long-term follow-up (LTFU) after interventional closure of the left atrial appendage (LAAC) in patients with nonvalvular atrial fibrillation (AF) are scarce. We sought to determine the outcome of patients after LAAC with the first generation device. METHODS AND RESULTS:The Cardioangiologisches Cen...
