This single-center retrospective cohort analysis looks into the impact of preoperative atrial fibrillation on post-LVAD outcomes. Within their cohort, they did not observe any difference in pump thrombosis and thromboembolic events with regard to this preoperative variable. Thereby, the authors concluded that the MAZE procedure, AF catheter ablation, or LAA exclusion might be of questionable impact within these patients. However, they urge a prospective evaluation of this topic.
