Evaluation of LVAD shows pump alarms and abnormal flow indicating mechanical malfunction. Which complication is this?

• A. Stroke
• B. RH failure
• C. Depression
• D. Device failure/death

Answer: (D)

When an LVAD shows pump alarms and abnormal flow, it signals a mechanical problem with the device itself. Alarms come from the controller or pump indicating hardware or driveline issues, while abnormal flow reflects that the pump isn’t circulating as intended. This situation is categorized as device failure/death because the root cause is a malfunction of the device rather than a physiologic complication like a stroke or a right‑sided heart problem. A stroke would involve neurologic symptoms from brain injury, not a direct pump alarm. Right heart failure can occur with LVAD support but wouldn’t typically present with device alarms or abnormal flow readings. Depression is not related to LVAD function.
