A LVAD recipient develops new-onset focal neurologic signs consistent with cerebrovascular event. Which complication?

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

Answer: (A)

New focal neurologic signs in an LVAD patient point to a cerebrovascular event, most likely a stroke. LVADs and the native circulation create surfaces and flow patterns that raise the risk for thrombus formation; a clot can form on the device or in the heart and break off to travel to cerebral vessels, causing an ischemic stroke. Anticoagulation helps reduce this risk but must be balanced against bleeding, so stroke remains a key concern in these patients. The focal deficits—such as sudden weakness, speech difficulty, or facial droop—reflect a localized brain injury from arterial occlusion or hemorrhage. The other options don’t fit the presentation: right heart failure shows systemic congestion and low forward flow rather than new focal neurologic symptoms; depression wouldn’t present with acute focal neurologic signs; device failure or death would typically manifest with device alarms, pump dysfunction, or hemodynamic collapse, not isolated neurologic deficits.
