First-in-man Percutaneous LAA Closure With an Amplatzer Amulet and TriGuard Embolic Protection Device in a Patient With LAA Thrombus

Percutaneous left atrial appendage (LAA) closure is currently utilized for the prophylaxis of thromboembolic cerebrovascular accidents in patients with non-valvular atrial fibrillation. The presence of LAA thrombus is usually considered a contraindication for the procedure, since there is a high risk of thrombus embolization. While reports in the literature have shown the feasibility of LAA closure in the presence of LAA thrombus with certain cerebral embolic protection devices, we present the first-in-man LAA closure of a patient with LAA thrombus using the TriGuard Embolic Protection Device.
