Left Atrial Appendage Occlusion

This information provides an overview of the Left Atrial Appendage Occlusion (LAAO) procedure. It is a treatment designed to reduce stroke risk in patients with atrial fibrillation (AFib) who cannot take long-term anticoagulant therapy. Below, you will find details on the purpose of the procedure, how it is performed, what to expect before and after the procedure, and the associated risks and benefits.

Left Atrial Appendage Occlusion (LAAO) is a minimally invasive procedure intended to reduce the chance of stroke in patients with AFib. The left atrial appendage (LAA) is a small sac in the left atrium of the heart where blood clots may form due to irregular heartbeats caused by AFib. By sealing off the LAA with a specialised device, the procedure prevents blood clots from entering the bloodstream and causing a stroke.

LAAO is typically recommended for patients who have non-valvular atrial fibrillation, are at high risk of stroke, and cannot take blood thinners due to bleeding risks or other contraindications.

Before the procedure, several tests will be done to assess your suitability. This may include a transesophageal echocardiogram (TEE), a CT scan, blood tests, and an ECG. You may also need to stop taking certain medications and fast for at least six hours before the procedure.

The LAAO procedure is performed under general anaesthesia. A small incision is made in the groin to access the femoral vein, through which catheters are introduced to the heart. A catheter with the occlusion device is advanced to the left atrial appendage, where the device is deployed to seal the area. Imaging techniques are used to ensure the device is correctly positioned and secured.

After the procedure, you will be closely monitored in a recovery area or intensive care unit (ICU). A transesophageal echocardiogram (TEE) may be performed to check the position of the occlusion device. You will be given medications to manage pain, prevent blood clots, and regulate heart rhythm.

Typically, the hospital stay lasts 1-2 days, but this may vary depending on your recovery and any complications. After discharge, you will need to continue taking prescribed medications and avoid strenuous activities. Follow-up appointments will be scheduled to monitor your progress and the function of the occlusion device.

Left Atrial Appendage Occlusion (LAAO) is an advanced procedure that effectively reduces stroke risk in patients with atrial fibrillation who cannot tolerate long-term anticoagulant therapy.
