What specific measurements are taken to assess LAA morphology?

The assessment of Left Atrial Appendage (LAA) morphology is critical for effective LAA occlusion procedures, as each anatomic characteristic can influence the choice of the occlusion device and procedure. The specific measurements taken to assess LAA morphology include the ostium, landing zone, and depth.

The ostium refers to the opening of the LAA and is crucial for determining how the occlusion device will fit and function. The landing zone is the area where the device will anchor after implantation. Understanding the depth provides information about how far the appendage extends, which can impact the device's positioning and the effectiveness of the occlusion.

Together, these measurements align closely with the individual anatomy of the patient and ensure a tailored approach to LAA occlusion, enhancing safety and efficacy.
