8.3 Biventricular assist device Several BiVAD configurations exist: paracorporeal pulsatile-flow BiVAD, an implantable LVAD coupled with a concurrent paracoporeal or percutaneous RVAD or two implantable CF-LVADs. These conficurations provide comparable outcomes [173]. The insertion of two implantable CF-LVADs as BiVAD configuration is predominatly performed at experienced centers. However, the application of a CF-LVAD as an implantable RVAD remains an off-label use.
