A ventricular assist device (also referred to as a VAD) is a mechanical device that assists the heart when the heart is too weak to adequately circulate blood to the body. These devices may be used to temporarily support a patient whose heart is failing due to injury or illness. They are also sometimes used to help support a patient’s failing heart until the patient can have a heart transplant (in notes the physician may refer to this as a “bridge to transplant”).
The ventricles of the heart are the natural “pumps” in the heart. The right ventricle pumps blood through the pulmonary artery and into the lungs to receive a fresh supply of oxygen while the left ventricle pumps blood out of the heart and into the aorta where it can circulate to the rest of the body. When one of the heart’s natural pumps fail, this can cause serious health problems and even death if left untreated.
A VAD can be placed to support the left ventricle, the right ventricle, or both. A VAD placed to support the left ventricle is sometimes referred to as an LVAD for short while a VAD placed to support the right ventricle is sometimes referred to as an RVAD for short. A VAD placed to support both ventricles of the heart is sometimes referred to as a biventricular VAD or a BIVAD for short. Continue reading “Ventricular Assist Devices”
