Massive air embolism with 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...

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...

Percutaneous right ventricular assist device for massive pulmonary embolism.

Treatment options for patients with mobile left ventricular thrombus and ventricular dysfunction: a case series

INTRODUCTION Little is known about the optimal management of large, mobile, pedunculated left ventricular clots. The management is particularly challenging in patients with advanced heart failure considered for left ventricular assist device implantation, because the clot may cause pump thrombosis. METHODS We retrospectively reviewed the records of patients with left ventricular thrombi ident...

Application of centrifugal pump in right ventricular failure due to pulmonary artery hypertension. (A case report)

Background: It has not been yet developed a ost suitable method to treat right ventricular failure due to pulmonar artery hypertention resulted from ventricular arrhythia. Though some case reports about patients ready to heart transplant using left assist device or biventral assist device as bridge have been published in Journals, but nocase concerning application of centrifugal pump for treatm...
