Mobile Left Atrial Thrombus Associated With Mitral Stenosis
A68-year-old woman presented with a 6-week history of shortness of breath on exertion. She had longstanding mitral stenosis and atrial fibrillation and was not taking oral anticoagulants.
Thirty years previously, she reportedly had had a stroke and made a full recovery. Transthoracic echocardiography (Figure 1⇓) demonstrated a freely mobile mass in the left atrium associated with severe mitral stenosis and mild aortic stenosis. The mass bounced around the atrium like a ball in a pinball machine.
