In LVAD failure, the pump stops working and the device fails, potentially fatal. Which complication?

Explanation:
The crucial idea is that losing the LVAD’s mechanical support directly causes loss of forward flow, leading to rapid systemic hypoperfusion, shock, and often death if not quickly reversed. When the pump stops, the heart cannot maintain circulation, so the most likely, immediate complication is device failure/death. Other problems like stroke can occur in LVAD patients due to thromboembolism or bleeding risks, and right heart failure can arise in the broader post-implant course, but they are not the direct, inevitable result of the pump failing. Depression is not a cardiopulmonary complication related to LVAD function.
