A case of outflow graft obstruction after EVAHEART2 implantation: role of device log analysis

Outflow graft obstruction (OGO) is a rare but potentially fatal complication of long-term left ventricular assist device use. This report presents a case of late-onset OGO caused by Candida albicans in a patient with an EVAHEART2. For EVAHEART2, which does not provide low-flow alarms, analysis of device log data revealing a gradual reduction in the maximum pump speeds and power consumption, as well as a gradual increase in the minimum pump speeds and power consumption, may be important for the early detection of OGO.
