Case Summary:
Left atrial appendage thrombus is commonly encountered in patients with severe mitral stenosis with atrial fibrillation. However, a large mobile left atrial thrombus is a rare but life-threatening condition. We report a case of severe mitral stenosis with atrial fibrillation in a patient who developed a large mobile left atrial thrombus despite anticoagulation.
Take-Home Messages:
Prompt diagnosis and urgent surgery played a crucial role in saving the patient from serious, potentially life-threatening complications. This case highlights the importance of maintaining an optimal international normalized ratio, early detection, and timely surgery for a better outcome.
