A person can live for a significant period without their biological heart if it's replaced with a Total Artificial Heart (TAH). For example, one individual lived for 555 days outside of a hospital with a TAH before receiving a heart transplant.
Living Without a Biological Heart
While the idea of living without a heart seems impossible, advancements in medical technology have made it a reality for some individuals with severe heart conditions. These individuals typically suffer from conditions like severe biventricular heart failure.
The Total Artificial Heart (TAH)
The Total Artificial Heart is a device that replaces the failing ventricles of the heart. It is designed to pump blood throughout the body, mimicking the function of a healthy heart. A TAH is typically used as a bridge to transplant, meaning it keeps the patient alive and stable until a donor heart becomes available.
Case Study: Stan Larkin
One notable example is Stan Larkin, who lived for 555 days outside of the hospital with a Total Artificial Heart. This allowed him to lead a relatively normal life while awaiting a heart transplant at the University of Michigan Health System (UMHS). This highlights the potential for TAHs to provide long-term support for patients with severe heart failure.
Factors Affecting Survival
The duration a person can live with a TAH varies depending on several factors, including:
- Underlying Health Conditions: The overall health of the patient plays a crucial role.
- Device Performance: The reliability and effectiveness of the TAH are essential.
- Access to Medical Care: Regular monitoring and follow-up care are vital.
- Complications: The risk of complications, such as infection or blood clots, can impact survival.
Limitations
It's important to acknowledge that while TAHs offer a lifeline, they are not a permanent solution. They are typically intended as a bridge to heart transplantation. Also, life with a TAH is not without its challenges, including the need for external power sources and potential complications.
