The first left ventricular assist device (LVAD) system was created by Domingo Liotta at Baylor College of Medicine in Houston in 1962. The first LVAD was implanted in 1963 by Liotta and E. Stanley Crawford. The first successful implantation of an LVAD was completed in 1966 by Liotta along with Dr. Michael E. DeBakey.
Berlin Heart manufactures two types of VADs: implantable and paracorporeal. INCOR is an axial-flow pump for support of the left ventricle.In this system, the pump is implanted directly next to the heart and is connected to the heart by cannula.
One parameter to quantify this difference is the pulsatility index (PI), which is equal to the difference between the peak systolic velocity and the minimum diastolic velocity divided by the mean velocity during the cardiac cycle. This value decreases with distance from the heart.
Thoratec's third-generation HeartMate LVAD is the HeartMate 3, [48] [49] designed to lower adverse event rates through improved hemocompatibility, and to increase ease of surgical placement through new design and compact size. [50] [51] It began undergoing clinical trials in the U.S. and internationally in mid 2014. [48] [49] [50] [52] [53]
The HeartAssist5 is a modern version of the DeBakey VAD [10] and as of December 2014 was the only remotely monitored medical device in the world. [8] It was first approved for use in Europe in 2009 under MicroMed Cardiovascular, Inc. [11] The HeartAssist5 is in use in Europe [10] as a destination therapy by patients who are not candidates to receive heart transplants and as a bridge to ...

In cardiovascular physiology, stroke volume (SV) is the volume of blood pumped from the ventricle per beat. Stroke volume is calculated using measurements of ventricle volumes from an echocardiogram and subtracting the volume of the blood in the ventricle at the end of a beat (called end-systolic volume [note 1]) from the volume of blood just prior to the beat (called end-diastolic volume).
