How long can an Impella typically remain in place?

• A. 2-4 hours
• B. 6-8 hours
• C. 12-24 hours
• D. 2-7 days

Answer: (B)

Impella is a temporary percutaneous left ventricular assist device used to provide short-term hemodynamic support during high-risk procedures or in acute cardiogenic situations. The typical dwell time reflects its role as a bridge during the immediate procedure and the early post-procedure period, not as a long-term implant. About 6–8 hours is a common window for ongoing support during the intervention and immediate post-procedure phase, after which the team reassesses and may remove the device if stabilization is achieved. Shorter durations, like 2–4 hours, may be insufficient for meaningful support, while longer durations (days) carry higher risks of vascular complications, hemolysis, and infection unless there is a clear ongoing need.
