The Dodrill–GMR heart machine, considered by some to be the first operational mechanical heart was successfully used while performing heart surgery. [1] [2] The machine performs the functions of the heart, allowing doctors to detour blood and stop the heart of a patient during an operation. The machine is external of the body and is only used ...
The LVAD is the most common device applied to a defective heart (it is sufficient in most cases; the right side of the heart is then often able to make use of the heavily increased blood flow), but when the pulmonary arterial resistance is high, then an (additional) right ventricular assist device (RVAD) might be necessary to resolve the ...

Impella heart pumps are percutaneous microaxial pumps that act as mechanical circulatory support devices in patients in need of hemodynamic support. [11] The pumps are mounted on support catheters and typically inserted through the femoral artery, although axillary and subclavian artery approaches are not uncommon. [12]
Forest Dewey Dodrill (January 26, 1902 – June 28, 1997) was a medical doctor at Harper University Hospital at Wayne State University in Michigan who performed the first successful open heart surgery using a mechanical pump. [1] [2]
“The heart will pump what it receives”- Starling’s law of the heart. The Frank–Starling mechanism describes the ability of the heart to change its force of contraction (and, hence, stroke volume) in response to changes in venous return. In other words, if the end-diastolic volume increases, there is a corresponding increase in stroke ...

William S. Pierce (born January 12, 1937) is an American cardiothoracic surgeon and chemical engineer who led development of the first pneumatic heart assist pump. The Pierce-Donachy Ventricular Assist Device, also known as the Penn State Assist Pump, was designated an International Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers in 1990.
