Current Trends in Implantable Left Ventricular Assist Devices

The shortage of appropriate donor organs and the expanding pool of patients waiting for heart transplantation have led to growing interest in alternative strategies, particularly in mechanical circulatory support. Improved results and the increased applicability and durability with left ventricular assist devices (LVADs) have enhanced this treatment option available for end-stage heart failure ...

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...

Effects of left ventricular assist devices on outcomes in patients undergoing heart transplantation.

BACKGROUND Left ventricular assist devices (LVADs) are increasingly being used to "bridge" patients to heart transplantation. METHODS Data from 40 consecutive status 1 heart transplantation patients treated with intravenous inotrope therapy (n = 20) or the HeartMate LVAD (n = 20) were retrospectively analyzed. RESULTS Baseline clinical characteristics were similar in the two groups. At the ...

LVAD: Left ventricular assist devices for end-stage heart failure.

Heart failure affects more than 5 million Americans with approximately 200,000 patients in end-stage disease that has failed traditional treatment. Historically, the only option for treatment was a heart transplant until left ventricular assist devices offered another option.
