Complications of a Giant Left Atrium - Extensive Thrombus Formation Despite Therapeutic Anticoagulation

Left atrial thrombus (LAT) formation is a feared complication of fibrillation, as it can lead to thromboembolic stroke or thromboembolism another peripheral region causing ischemia. Despite therapeutic anticoagulation, recurrence thrombi still possible, although unlikely. Prevention strategies may include reducing left size along with treatment by surgical removal. We present case patient large in the setting previous mitral valve stenosis and current fibrillation.
