Abstract:
An 89-year-old woman underwent left atrial appendage (LAA) closure (LAAC) in our hospital because of recurrent gastrointestinal bleedings. The first transesophageal echocardiography (TEE) follow-up at six weeks revealed a complete sealing of the LAA and no device related thrombus. In a TEE follow-up at one year after the LAA closure, a large device related thrombus (6 × 3 cm) was found. Treated with oral anticoagulation (apixaban) the thrombus showed a partial resolution one year later.
