What are some potential long-term complications after LAAO?

Device embolization and late thrombus formation are indeed recognized potential long-term complications following left atrial appendage occlusion (LAAO). After the procedure, there is a risk that the implanted device may migrate from its position, which can lead to embolization. This can result in serious adverse events, including stroke. Additionally, there is a possibility of thrombus formation on the surface of the device or within the left atrial appendage itself, which could also lead to embolic events.

The nature of LAAO is to mitigate the risk of thromboembolism in patients with atrial fibrillation, but complications such as device-related thrombus formation can counteract the intended benefits and necessitate careful monitoring over time. Hence, awareness of these specific complications is crucial for ongoing patient management and safety after the procedure.
