Yes, there is a device considered a "fake heart," also known as a total artificial heart (TAH).
What is a Total Artificial Heart (TAH)?
A total artificial heart (TAH) is a mechanical device designed to replace the lower chambers of the heart, the ventricles. These devices are used when a person's own heart ventricles are too damaged or diseased to pump blood effectively.
How a TAH Works
- The TAH takes over the role of the ventricles.
- It pumps blood throughout the body, restoring healthy circulation.
- This allows the person's circulatory system to function correctly.
- The TAH is implanted during surgery.
Why Use a TAH?
A TAH is a critical solution when the natural heart ventricles are failing, making it impossible for the heart to pump sufficient blood. TAHs are often used as a bridge to a heart transplant, giving patients time before a suitable donor heart becomes available.
Comparison Table: Natural vs Artificial Heart
| Feature | Natural Heart | Total Artificial Heart (TAH) |
|---|---|---|
| Function | Pumps blood with natural ventricles | Replaces lower heart chambers (ventricles) and pumps blood |
| Material | Biological tissue | Mechanical parts |
| Energy Source | Internal biological system | External power source (typically battery) |
Conclusion
The total artificial heart (TAH) serves as a mechanical substitute for the natural heart's ventricles, making it a form of a "fake" heart. It effectively restores circulation when the natural heart fails.
