Abstract:
A rare case of left atrial free floating ball thrombus with mitral stenosis is reported. A 66-year-old woman was admitted for epigastralgia and acute heart failure without atrial fibrillation and previous embolization. The patient was treated successfully with removal of ball thrombus and mitral valve replacement. Intraoperative transesophageal echocardiography was effective for monitoring of mobile left atrial thrombus.
