Congestive Heart Failure (CHF) Practice Test

BiVAD refers to a device providing mechanical support for which parts of the heart?

Left ventricle only Both ventricles Right ventricle only Atria

Correct Answer:

Both ventricles

Explanation:

BiVAD means a biventricular assist device, which provides mechanical support for both ventricles. In advanced heart failure, either or both ventricles may not pump effectively. An LVAD helps the left ventricle move blood into the aorta, while an RVAD helps the right ventricle push blood into the pulmonary artery. A BiVAD uses two pumps to assist both sides, improving overall cardiac output by supporting circulation to both the systemic and pulmonary circuits. Supporting only one ventricle or the atria isn’t what BiVAD is designed to do, so the best choice is the device that aids both the left and right ventricles.
