The left atrial appendage is a pouch-like structure in the left upper chamber of the heart. In patients with atrial fibrillation (fast rhythm disorder), 90% of the clots get formed in the left atrial appendage. If a clot travels through the arteries, it may cause a stroke. In specific patients, the left atrial appendage can be closed with a minimally invasive procedure, providing a great treatment option in this population. Our physicians are experts and are performing these procedures in high volume US centers.
