Abstract:
An 83-year-old man with known history of atrial fibrillation presented for preoperative evaluation for elective left nephrectomy for cancer. Transthoracic echocardiogram revealed a large, free-floating, left atrial mass. Further profiling with transesophageal echocardiogram showed a free-floating mass intermittently obstructing the mitral valve.
