What type of procedure is associated with Surgical LAAO?

Surgical LAAO is classified as an epicardial procedure because it involves accessing the left atrial appendage (LAA) through the epicardial surface of the heart. During this surgical approach, a surgeon typically uses direct visualization to locate and occlude the LAA, thereby preventing thrombus formation and reducing the risk of stroke in patients with atrial fibrillation. This type of procedure is distinct from others like percutaneous approaches, which involve catheter-based techniques, or minimally invasive methods that may utilize different access points or instruments. Epicardial procedures play a crucial role in the comprehensive management of patients at risk for embolic events due to atrial fibrillation.
