What is required for a device to pass the stability criteria during assessment?

For a device to successfully meet stability criteria during assessment, it is essential that it remains stable with no movement. This requirement is critical because the primary goal is to ensure that the device can reliably function in the intended position throughout the patient's treatment. If the device exhibits movement, it may not effectively occlude the left atrial appendage, potentially leading to complications, such as thrombus formation or ineffective sealing, which could increase the risk of embolic events.

The focus on stability emphasizes the importance of secure placement and reliable function, which are vital in achieving the desired clinical outcomes in procedures involving left atrial appendage occlusion. Meeting this criterion ensures the device's effectiveness and the safety of the patient’s overall cardiac management.
