Which of the following is a long-term complication associated with LAAO?

Device embolization is a recognized long-term complication associated with Left Atrial Appendage Occlusion (LAAO). This occurs when the implanted device inadvertently migrates from its intended position in the left atrial appendage, which can lead to serious complications such as stroke or other cardiovascular issues.

Understanding device embolization highlights the importance of careful patient selection and procedural technique during LAAO, as well as the need for thorough follow-up care. While other choices may suggest beneficial outcomes or improvements (like increased exercise tolerance or cognitive improvements), they do not represent complications. Device embolization must be monitored to ensure the safety and efficacy of the procedure in preventing thromboembolic events related to atrial fibrillation.
