How is LAAO typically assessed after the procedure?

Assessing LAAO after the procedure is primarily conducted with transesophageal echocardiography (TEE) to evaluate device placement. This imaging technique allows for a close examination of the left atrial appendage and ensures that the occlusion device is positioned correctly and functioning as intended. TEE provides high-quality images and can identify any potential complications such as device leakage or thrombus formation, which could lead to adverse outcomes if not detected.

While physical examinations, follow-ups, and patient-reported symptoms can certainly play a role in post-procedure assessments, they do not provide the detailed anatomical information that TEE offers. TEE is a standard and crucial part of the assessment protocol to confirm the safety and effectiveness of the intervention.
