Why is the orientation of the device important when deploying the LAAO device?

The orientation of the LAAO device is critical because the axis of the device lobe must align with the left atrial appendage (LAA) neck to ensure an effective closure. Proper alignment ensures that the device can adequately seal the LAA and prevent blood clots from forming within it, which is a primary goal of the procedure. Misalignment could lead to incomplete occlusion, increasing the risk of thromboembolic events, such as stroke. Additionally, the correct orientation facilitates effective anchoring of the device, contributes to optimal hemodynamics, and minimizes the risk of complications. Overall, achieving correct alignment during deployment ultimately supports the procedure's success and the patient’s safety.
