Does the duration of postimplantation dual antiplatelet therapy prevent device-related thrombus in patients undergoing left atrial appendage occlusion?
In a real-world series, device-related thrombus after LAA occlusion was associated with patient and procedural characteristics, but not with the duration of postimplantation dual antiplatelet therapy.
BACKGROUND: Device-related thrombus (DRT) after left atrial appendage occlusion is a worrisome finding with little knowledge about when to expect it and how to prevent it. This study sought to investigate correlates of DRT after left atrial appendage occlusion, its time of diagnosis, and particularly, association with postimplantation dual antiplatelet therapy duration. METHODS AND RESULTS: =0.77). CONCLUSIONS: In this real-world series, DRT was observed early, late, and very late after left atrial appendage occlusion. It was related to patient and procedural characteristics but not to postimplantation dual antiplatelet therapy duration.
