According to a retrospective cohort study comparing patients treated with a left ventricular assist device versus inotrope therapy while awaiting heart transplantation, the group treated with LVAD had improved clinical and metabolic function at the time of transplant with better blood pressure, sodium, blood urea nitrogen, and creatinine.
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.
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 ...
Until recently, the only other available device-based treatment was the left ventricular assist device (LVAD). LVAD therapy is indicated in patients with severe illness and is associated with several hours of surgery (involving a cardiopulmonary bypass). It is usually considered as a therapy providing a "bridge to transplant" for heart failure ...
Bridge to decision: A decision will soon be made about what to do next (that is, which definitive therapy will come soon), but first the patient needs a bridge to support them until that decision; for example, short-term mechanical circulatory support as a bridge to durable left ventricular assist device implant in refractory cardiogenic shock ...
Impella is a family of medical devices used for temporary ventricular support in patients with depressed heart function. Some versions of the device can provide left heart support during other forms of mechanical circulatory support including ECMO and Centrimag.

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 ...
