Left Atrial Appendage Ligation is a minimally invasive surgical procedure performed to treat patients with atrial fibrillation, a condition characterized by irregular heart rhythms. The left atrial appendage (LAA) is a small, ear-shaped sac in the muscle wall of the left atrium where blood clots can form and contribute to strokes in patients with atrial fibrillation.

During the procedure, the surgeon accesses the heart through small incisions in the chest, often using a video-assisted thoracoscope or a robotic surgical system for better visibility and precision. The left atrial appendage is then identified, and a special device or suture is used to seal off or “ligate” the appendage. This prevents the blood from entering and clotting in the appendage, thereby

reducing the risk of stroke.

The procedure can be performed as a standalone operation or in conjunction with other heart surgeries. It may be an alternative for patients who cannot tolerate long-term anticoagulation therapy.

Left Atrial Appendage Ligation is typically performed under general anesthesia and may require a hospital stay of a few days for monitoring and recovery. As with any surgical procedure, it carries certain risks, including bleeding, infection, and complications related to anesthesia. However, it can significantly reduce the risk of stroke in patients with atrial fibrillation, improving their quality of life.

Post-operatively, patients will require regular follow-up appointments to monitor their recovery and ensure the effectiveness of the ligation. It’s essential for patients to maintain communication with their healthcare providers and report any new or worsening symptoms promptly.
