The LVAD is the most common device applied to a defective heart (it is sufficient in most cases; the right side of the heart is then often able to make use of the heavily increased blood flow), but when the pulmonary arterial resistance is high, then an (additional) right ventricular assist device (RVAD) might be necessary to resolve the ...
A wearable cardioverter defibrillator (WCD) is a non-invasive, external device for patients at risk of sudden cardiac arrest (SCA). [1] It allows physicians time to assess their patient's arrhythmic risk and see if their ejection fraction improves before determining the next steps in patient care.
Berlin Heart GmbH is a German company that develops, produces and markets ventricular assist devices (VADs). The devices mechanically support the hearts of patients with end-stage heart failure. Berlin Heart's products include the implantable INCOR VAD and the paracorporeal EXCOR VAD. To date, Berlin Heart produces the only device of its kind ...
The HeartAssist5 is a modern version of the DeBakey VAD [10] and as of December 2014 was the only remotely monitored medical device in the world. [8] It was first approved for use in Europe in 2009 under MicroMed Cardiovascular, Inc. [11] The HeartAssist5 is in use in Europe [10] as a destination therapy by patients who are not candidates to receive heart transplants and as a bridge to ...
More modern devices have software designed to attempt a discrimination between ventricular fibrillation and ventricular tachycardia (VT), and may try to pace the heart faster than its intrinsic rate in the case of VT, to try to break the tachycardia before it progresses to ventricular fibrillation. This is known as overdrive pacing, or anti ...
With the 2001 Thermo Cardiosystems merger, Thoratec acquired the HeartMate Left Ventricular Assist System, an implanted VAD for end-stage heart patients. A landmark three-year study of 129 patients at 22 major medical centers, called REMATCH (Randomized Evaluation of Mechanical Assistance for the Treatment of Congestive Heart Failure) and published in November 2001, found that the HeartMate VE ...

Ventricular assist devices require open-heart surgery for implantation. An incision is made through the breastbone to expose the heart. Heparin will be given to keep the patients blood from clotting. The blood is rerouted to a heart-lung machine that will pump and oxygenate blood. A pocket for the LVAD is formed in the abdominal wall.
