Abstract
Perioperative use of the Impella device has become common in the management of cardiogenic shock. Bleeding and thrombotic complications associated with mechanical circulatory support devices can occur. The incidence and risk factors of thrombotic complications associated with the Impella remain unclear. We herein report a case of extensive intra-aortic thrombosis following Impella CP-assisted surgical ventricular septal perforation repair in an elderly woman. Since there seemed to be no abdominal malperfusion and considering her advanced age and frailty, conservative treatment was selected. Intensive anticoagulation therapy with heparin and warfarin was started. The aortic thrombus regressed, and the patient was discharged without major kidney or gastrointestinal complications. In conclusion, thromboembolic complications should be considered in a perioperative setting.
