Özet
Incomplete surgical left atrial appendage (LAA) closure is associated with increased thromboembolic risk in atrial fibrillation patients. We present a case of successful percutaneous closure of a significant residual leak following surgical LAA ligation. A 64-year-old female with atrial fibrillation (CHA₂DS₂-VASc score 4), prior surgical interventions including LAA ligation for thrombus formation, presented with ischemic stroke despite anticoagulation. Transesophageal echocardiography revealed a 10 mm residual communication following incomplete LAA closure. Percutaneous closure was performed using a 31 mm Amplatzer Amulet device with successful leak elimination. Percutaneous closure of residual leaks following incomplete surgical LAA closure represents a viable alternative to repeat surgery in high-risk patients. Individualized antithrombotic therapy is essential for optimal outcomes.
