What is the primary function of a Ventricular Assist Device (VAD)?

The primary function of a Ventricular Assist Device (VAD) is to pump blood to the body. A VAD is a mechanical device designed to support heart function and blood flow in individuals with weakened hearts, typically those suffering from severe heart failure. By providing additional assistance to the heart’s pumping action, the device helps ensure that an adequate supply of blood, which carries oxygen and nutrients, reaches the body's organs and tissues.

This function is particularly crucial for patients who may be awaiting a heart transplant or those who are not candidates for surgery. By effectively taking over the role of pumping blood, VADs can improve patients' quality of life, allowing them to engage in daily activities with greater energy and stability. The emphasis on assisting with blood flow distinguishes the VAD from other options that might involve intervention at the level of the heart valves, monitoring of heart rate, or regulation of blood pressure.
