Left atrial appendage (LAA) closure refers to interventional procedures aimed at closing a blockage in the left atrium (left atrial appendage). The left atrial appendage is a structure in the upper left region of the heart that has the potential for blood clots to form. These clots can be caused by rhythm disturbances such as atrial fibrillation and can lead to serious complications such as cerebral palsy. LAA closure procedures offer a treatment option to reduce this risk.

These procedures are usually performed with a catheter. The catheter is usually inserted through the groin or thigh and is used to place a closure device in the LAA. The occluder device closes the LAA and prevents clots from forming by keeping blood flowing regularly in this area. The procedure is less invasive than surgery and usually provides a short recovery time.

Left atrial appendage closure procedures are generally preferred in patients with atrial fibrillation, non-compliance with anticoagulant medications or those at risk of bleeding. This interventional treatment option is used to improve patients’ quality of life and minimize the risk of serious complications. However, as each patient is different, the treatment plan should be customized according to the patient’s condition and characteristics. These procedures are usually performed by a team of specialists, such as cardiologists and cardiovascular surgeons.
