HVAD, a support heart that is used in the Netherlands
HVAD stands for Heartware Ventricular Assist Devise and is an LVAD developed by the firm Heartware. This company was taken over in 2016 by Medtronic
The HVAD has been implanted in the Netherlands since 2010. This was the first support heart to be used alongside the HeartMate II and has a number of advantages over the Heartmate II.
To begin with, this pump is much smaller, has a 'floating' mechanical drive and is implanted in the pericardium. This has proven to be a great advance over the Heartmate II which is an axially driven pump placed in the chest cavity, below the diaphragm. The successor to the Heartmate II is comparable to the HVAD, the Heartmate 3. The differences between the two are explained here.
