A patient with LVAD develops sudden confusion, weakness, and trouble speaking. Which complication is most probable?

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

Answer: (A)

In LVAD patients, sudden focal neurologic changes strongly point to a cerebrovascular event. The combination of sudden confusion, weakness, and trouble speaking suggests a stroke, which is a well-known and serious complication in LVAD recipients. Strokes can be ischemic from thromboembolism related to the device or its anticoagulation, or hemorrhagic due to anticoagulation balance and device-related factors. The signs localize to a brain territory responsible for language and motor function, often the left hemisphere (e.g., an MCA territory stroke).

Other options don’t fit the acute presentation as well. Right-sided heart failure would produce systemic congestion signs (edema, hepatomegaly, jugular venous distention) rather than abrupt focal neurologic deficits. Depression doesn’t cause sudden weakness or language disturbance. Device failure would typically lead to pump-related hemodynamic collapse, low output symptoms, or system-wide instability rather than a focal neurologic event.
