Ventricular assist device selection: which one and when?

Ventricular assist device selection: which one and when?

Advances in mechanical circulatory support have significantly expanded the treatment options for patients with heart failure, whether acute or chronic. There are numerous devices available that offer patients short-, intermediate-, and long-term duration of support depending on their clinical needs and cardiac recovery. Each device has its own technical considerations and the decision which dev...

Ventricular Assist Device-Specific Infections

Ventricular assist devices (VADs) have been shown to offer a significant survival benefit over medical therapy in patients with advanced heart failure. Despite significant advances in device technology and surgical technique, VAD-specific infections still remain among the most common causes of morbidity and mortality in patients with VADs. VAD-specific infections may involve the driveline exit ...

Ventricular arrhythmias after left ventricular assist device.

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...

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...
