What is the primary indication for Left Atrial Appendage Occlusion (LAAO)?

The primary indication for Left Atrial Appendage Occlusion (LAAO) is to prevent stroke in patients with atrial fibrillation who are at high risk for thromboembolism. Atrial fibrillation can lead to the formation of blood clots in the left atrial appendage due to stagnant blood flow, increasing the risk of these clots dislodging and causing a stroke. The LAAO procedure involves occluding the left atrial appendage to reduce the risk of stroke by minimizing the likelihood of thrombus formation in this area.

This intervention is particularly important for patients who cannot tolerate long-term anticoagulation therapy due to bleeding risks or other contraindications. By sealing off the appendage, the procedure addresses the source of potential thrombus formation while providing an alternative to traditional anticoagulation methods for stroke prevention in this population.
