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...

Design of Supervisory Control System for Ventricular Assist Device

When a patient have severe heart diseases, Ventricular Assist Device (VAD) implantation may be necessary. However, the improvement of the interaction between the device and the patient's behavior is crucial. Currently, the control of these pumps does not follow changes in patient behavior and the devices are no safe. Therefore, if VAD has no faults tolerance and no dynamic behavior according to...

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 ...

Evaluation for a Ventricular Assist Device

Case presentation: A 57-year-old woman with ischemic and valvular heart disease presents with progressive heart failure while awaiting cardiac transplantation. Several years ago, after a large anterior myocardial infarction, she underwent 4-vessel CABG. Her subsequent course was complicated by atrial fibrillation and then recurrent heart failure. She also developed progressive aortic stenosis a...
