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...
متن کاملImprovement 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...
متن کاملLeft ventricular assist devices decrease fixed pulmonary hypertension in cardiac transplant candidates.
OBJECTIVE Fixed pulmonary hypertension is a contraindication for cardiac transplantation because of the increased risk of donor heart failure. We sought to determine whether left ventricular assist devices improve fixed pulmonary hypertension in cardiac transplant candidates to enable safe cardiac transplantation. METHODS Thirty-five consecutive cardiac transplant candidates (age 56 +/- 6 yea...
متن کاملEthical challenges with the left ventricular assist device as a destination therapy
The left ventricular assist device was originally designed to be surgically implanted as a bridge to transplantation for patients with chronic end-stage heart failure. On the basis of the REMATCH trial, the US Food and Drug Administration and the US Centers for Medicare & Medicaid Services approved permanent implantation of the left ventricular assist device as a destination therapy in Medicare...
متن کاملClinical and cost-effectiveness of left ventricular assist devices as destination therapy for people with end-stage heart failure: a systematic review and economic evaluation.
OBJECTIVES The clinical and cost-effectiveness of left ventricular assist devices as destination therapy for people with end-stage heart failure is assessed through a systematic review and economic evaluation. METHODS Systematic review was performed of randomized controlled trials, quasiexperimental studies, case series, and case studies identified through searching eighteen electronic databa...
متن کاملAtypical tamponade hemodynamic in a patient with temporary left ventricular assist device.
Postoperative bleeding and tamponade are considered major complications after implantation of left ventricular assist devices. Firstly, 40% of patients supported by ventricular assist devices experience early postoperative bleeding, and 20% developed tamponade requiring re-exploration. Secondly, we present a case of a patient with tamponade, on temporary left ventricular assist device (LVAD) su...
