Incidence, predictors and outcomes of device‐related thrombus after left atrial appendage closure with the WATCHMAN device—Insights from the EWOLUTION real world registry

Abstract

In real-world patients undergoing LAAc with the WATCHMAN device, DRT is rare. DRT was most frequently detected within the first 3 months after LAAc regardless of post-procedural regimen and was not associated with an increased risk of stroke or SE. While long-standing atrial fibrillation was the only independent factor associated with DRT, medical treatment of DRT resulted in a resolution of thrombi in most cases.
