Beating heart implantation of a wearable NOVACOR left-ventricular assist device.

چکیده
Implantable left-ventricular assist devices (LVAD) are successfully used as a bridge to transplant if the patient's condition is worsening and no donor organ is available. They allow recovery of compromised organ function. However, postoperative bleeding, thrombemboelism, and right-heart failure may jeopardize the important improvement of organ function and may even lead to death. We introduce our strategy for implantation of the Novacor LVAD system, which aims at minimal bleeding and maintained right-heart function. The Novacor LVAD was implanted with the heart beating during extracorporeal circulation in 8 patients, 3 of whom had previous cardiac surgery. Postoperatively, no patient developed right heart failure or had to undergo redo thoracotomy.

Permanent pacing in a patient with a left ventricular assist system.
A patient with end stage heart failure underwent permanent implantation of a Novacor left ventricular assist system. Progressive right ventricular dysfunction developed during the first two postoperative weeks. Temporary and subsequently permanent atrioventricular pacing to correct first degree heart block improved the performance of the device, with sustained resolution of his right ventricula...
متن کاملDesign 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 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...

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 کاملAllosensitization in bridge to transplant Novacor left ventricular assist device patients: analysis of long-term outcomes with regard to acute rejection and chronic allograft vasculopathy.
BACKGROUND The true relevance of allosensitization in patients benefiting from left ventricular assist device (LVAD) as bridge to transplant (BTT) is still debated. Available registry data referred to numerous devices precluding LVAD-specific analysis. Therefore, we studied all patients with Novacor LVAD prior to transplantation. METHODS From 1985 to 2006, 37 Novacor LVADs were implanted as B...
