A Left Ventricular Assist System (LVAS) is a mechanical device that takes over the work of a failing heart.

 

LVAS Therapy

A Left Ventricular Assist System, or LVAS, is a type of mechanical circulatory device specifically designed to improve the lives of patients waiting for donor hearts, as well as those who are ineligible for a transplant.

WHAT IS AN LVAS?

This medical device uses a mechanical pump to help the weakened heart pump blood throughout the body. It can be implanted inside the body or reside outside the body.

In a healthy heart, the left ventricle is the primary pumping chamber. The left side of the heart delivers oxygen-rich blood to all parts of the body. Used blood returns to the right side of the heart and is sent to the lungs to be “refueled” with oxygen.

A failing heart is too weak to pump enough blood to the body. An LVAS takes over the additional work load and helps the left ventricle pump oxygenated blood throughout the body. As a result, vital organs receive more oxygen than they did before, and heart failure patients who receive an LVAS often feel better and have more energy.

WHO NEEDS AN LVAS?

An LVAS is intended for end-stage heart failure patients (classified in NYHA class IV, or ACC/AHA stage D) who are unable to receive a heart transplant due to donor availability, eligibility or other factors. The types of patients who may benefit from LVAS treatment include:
