The smallest device approved by the FDA, the HeartMate II, weighs about 1 pound (0.45 kg) and measures 3 inches (7.6 cm). This has proven particularly important for women and children, for whom alternatives would have been too large. [45] As of 2017, HeartMate III has been approved by the FDA.
Thoratec next developed a second-generation LVAD product line, a continuous-flow VAD called HeartMate II. The new device, one-fifth the size of the HeartMate XVE, was designed to last more than twice as long as the XVE, providing mechanical circulatory support for three to five years or more before replacement.
O. H. "Bud" Frazier is a heart surgeon and director of cardiovascular surgery research at the Texas Heart Institute (THI), best known for his work in mechanical circulatory support (MCS) of failing hearts using left ventricular assist devices (LVAD) and total artificial hearts (TAH).
In 2000, the Randomized Evaluation of Mechanical Assistance for the Treatment of Congestive Heart Failure (REMATCH) trial was conducted. REMATCH was a multi-center study supported by the National Heart, Lung, and Blood Institute to compare long-term implantation of left ventricular assist devices with optimal medical management for patients with end-stage heart failure who require, but do not ...

A key feature of CAA systems is the automated analysis of the recorded audio signals by signal processing algorithms. Such algorithms can run directly on the device used for making the recording, or be hosted in a cloud connected to the device. The degree of autonomy of currently available analysis algorithms varies greatly.
