A heart pump is called a ventricular assist device (VAD).
What is a Ventricular Assist Device (VAD)?
A ventricular assist device (VAD) is a mechanical pump that supports a failing heart. It helps pump blood from the heart's lower chambers (ventricles) to the rest of the body. VADs are used for individuals whose hearts are too weak to pump blood efficiently on their own. According to the reference, VADs are often used as a treatment for a weakened heart or heart failure. They can also serve as a bridge to other treatments, like a heart transplant, helping the heart work while waiting for a more permanent solution.
Why Use a VAD?
VADs are not a long term solution, but rather a temporary bridge for those who have a damaged heart:
- Heart Failure: When the heart is too weak to effectively pump blood, a VAD provides the necessary support.
- Bridge to Transplant: VADs help patients survive while they wait for a suitable heart donor.
- Support During Treatment: Sometimes, a VAD may be used while other treatments for heart conditions are ongoing.
How Does a VAD Work?
A VAD is implanted inside the body and connected to the heart. It essentially takes over the pumping function of the weakened ventricle(s). The device helps circulate blood throughout the body, ensuring that vital organs receive the necessary oxygen and nutrients.
Types of VADs
VADs come in various designs and complexity, but they all share the same core function - to assist a failing heart. Some are designed to support just the left ventricle (LVAD), some the right ventricle (RVAD) and some both (BIVAD).
