Impella left-sided heart pumps are used to support the blood-pumping ventricles of the heart during surgery for opening a blocked artery or clearing blockages after a heart attack. They may also be used during open heart surgery, post-heart attack, when an individual’s heart has been damaged to the extent that it can no longer supply sufficient blood or oxygen to the body (cardiogenic shock), or for those who suffer from diseases of the heart muscle (Cardiomyopathy). Use of the pump is aimed to allow the heart to recover while maintaining the circulatory system.
