Ischemic stroke associated with high-grade pedunculated device-related thrombosis following left atrial appendage closure

Abstract

We have seen ischemic stroke associated with a high-grade device-related pedunculated thrombosis after left atrial appendage closure (LAAC) after discontinuation of oral anticoagulations (OACs). Continuation of OACs, including half-dose direct oral anticoagulations after LAAC, may be a better option for patients at high risk of thromboembolism to prevent further thromboembolic events.
