Which device is surgically implanted and can serve as a long-term support option?

• A. IABP
• B. Impella
• C. LVAD
• D. External pump

Answer: (C)

Providing durable, long-term support for end-stage heart failure requires a device that is surgically implanted and designed for extended use. The LVAD fits because it is placed inside the chest, with a pump that connects the left ventricle to the aorta, delivering ongoing circulatory support. This allows it to function as destination therapy for patients who aren’t transplant candidates, or as a bridge to transplantation while a donor is sought. In contrast, the other options are temporary or non-implanted solutions: IABP is a catheter-based device used for short-term support and unloading of the heart; Impella is also a percutaneous, short-term pump; an external pump remains outside the body and isn’t suitable for long-term internal support.
