| Sumario: | A 55-year-old woman who had received an implantable left ventricular assist device 3
months earlier presented with dyspnea and a low-flow alarm of the device. Computed
tomography and log-file analysis of the device system suggested inflow cannula obstruction.
Since the patient had cardiogenic shock due to pump failure, venoarterial extracorporeal
membrane oxygenation (ECMO) was initiated. With ECMO, surgical exchange of the
pump was considered. However, the obstruction spontaneously resolved without surgical
intervention. It turned out that an obstructive thrombus was washed out by rebooting the
pump. Moreover, the thrombus was embolized in the patient’s left subclavian artery. The
patient underwent heart transplantation 4 months after the pump obstruction accident
and continued to do well. |
