Left Ventricular Assist Devices—Early New Zealand Experience

Left Ventricular Assist Devices.

Innovation with experience using implantable left ventricular assist devices.

The National 1Institutes of Health’s artificial heart program, initiated in 1964, has generated sustained and coordinated efforts by industry and academic engineers and investigators to create and develop mechanical circulatory support devices to prolong and enhance the lives of patients with advanced heart failure. These efforts have been supported by a combination of federal, industry, and ph...

HeartMate II left ventricular assist device; early European experience.

OBJECTIVE The novel axial flow left ventricular assist device HeartMate II was introduced into clinical practice in Europe as part of the pilot study and after CE approval in November 2005. In order to get an overview of the use and performance of the device in Europe a group of investigators was founded to compare the initial results. METHODS In a retrospective analysis of the first 101 cons...

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...
