Abstract:
An 85-year-old woman with atrial fibrillation was found to have a large 4.5- × 3.5-cm left atrial mass. Transcatheter left atrial mass extraction was performed using an aspiration cannula, through which the bulk of the mass was retrieved. However, a fragment of the mass broke off and embolized distally. Right femoral arterial cutdown with distal thrombectomy was performed and a large chunk of the embolized mass was retrieved. Pathology of the specimen showed complex thrombus.
