Sudden power loss in a heartmate II left ventricular assist device due to intermittent pin contact with the battery: Case report

摘要

Left ventricular assist device technology has improved such that mechanical malfunction, particularly with newer generation continuous flow devices, is a relatively rare event. We present a case of sudden power loss in a HeartMate II caused by intermittent contact of the battery terminals after a clip was dropped with the battery inserted in it. The clip was replaced and the patient made a complete recovery. A new inspection and testing methodology, and amended approach to patient and caregiver training, designed to prevent future occurrences is described.
