Congenital absence of the left atrial appendage: a positive coincidence for the electrophysiologist? A case report
The congenital absence of the LAA raises important considerations for managing stroke risk in AF patients, as standard thromboembolic risk scores do not account for such anatomical variations. Despite the LAA being the most common site for thrombus formation, stroke risk in AF results from multiple factors beyond a single site of thrombus formation. Left atrial appendage occlusion is a viable alternative for stroke prevention in patients contraindicated for anticoagulation. Recent guidelines recommend individualized risk assessment using scores such as CHA<sub>2</sub>DS<sub>2</sub>-VA, even in atypical cases, ensuring that management strategies are tailored to each patient's risk profile.
