100 patients supported for over one year on an implanted left ventricular assist device

Design an Equivalent Left Ventricular Assist Device for Medical Equipment Labs

LVAD is a mechanical pump supporting a weak heart function and blood flow. Sometimes, the heart may not recover fast enough to take over the pumping action immediately after surgery, in such patients a temporary support device has been employed to maintain the pumping action until the patient’s own heart recovers. This device can be considered as a temporary alternative before the process of ar...

Impact of Socioeconomic Status on Patients Supported With a Left Ventricular Assist Device

Socioeconomic status (SES) has been identified as a risk factor for heart failure, hospital readmission, and mortality. Among patients who progress to Stage D heart failure, both heart transplantation and left ventricular assist devices (LVADs) provide improved quality of life and survival. Previous studies have identified race and SES as a risk factor for decreased post-transplant survival in ...

Quality of Life and Influential Factors in Patients Implanted With a Left Ventricular Assist Device.

BACKGROUND Improving quality of life (QOL) has become an important goal in left ventricular assist device (LVAD) therapy. We aimed (1) to assess the effect of an implantable LVAD on patients' QOL, (2) to compare LVAD patients' QOL to that of patients in different stages of heart failure (HF), and (3) to identify factors associated with patients' QOL. METHODSANDRESULTS The QOL of 33 Japanese i...

Improvement of Left Ventricular Assist Device (LVAD) in Artificial Heart Using Particle Swarm Optimization

In this approach, the Left ventricular assist pump for patients with left ventricular failure isused. The failure of the left ventricle is the most common heart disease during these days. Inthis article, a State feedback controller method is used to optimize the efficiency of a samplingpump current. Particle Swarm Algorithm, which is a set of rules to update the position andvelocity, is applied...
