Impella: World's Smallest Heart Pump 3D Parallel View
This 3D stereographic photo is of the Impella device, a family of heart pumps developed by Abiomed. It is used for temporary ventricular support in patients with reduced heart function. An example of its use would be for cardiogenic shock following a myocardial infarction (heart attack) or in high risk percutaneous coronary intervention (essentially placing a stent in a coronary artery to relieve a heart attack).
The device is pretty amazing as the small impeller inside is able to achieve high flow rates (with a max of 5 L/min depending on the model) using extremely high speeds up to 51,000 RPM.
If there is left heart dysfunction, the left-sided support version of the device is threaded through a peripheral artery such as the femoral, subclavian, or axillary artery until it reaches into the left ventricle. It would cross the aortic valve and pump blood from the left ventricle into the aorta. This provides three physiological benefitial effects: unloading of the left ventricle leading to decreased stress/work/myocardial oxygen demand, increased tissue perfusion via increased arterial pressure and cardiac output, and reduction of right ventricular afterload which improves forward flow.
For right heart dysfunction, the right ventricular assist version of the device can be threaded through the femoral vein up to the heart where it would sit in pulmonary artery. It would cross the pulmonary valve and pump blood from the inferior vena cava into the pulmonary artery.
