Intraoperative left atrium inversion after implantation of HeartMate III ventricular assist device.

We report here a case of left atrium inversion after implanting HeartMate III LVAD, which is known to be the first in literature. LVAD can be functional only if there is adequate inflow to the device. Parameters and filling of left ventricle can be assessed by TEE. In our case, initial examination with TEE showed thrombus like images. HeartMate III has a reliable algorithm that automatically reduces pump speed if 'suction effect' is detected. HeartMate III demonstrates clean flow properties and good surface wash. Despite these positive features of the HeartMate III, left atrium inversion can still be seen with it, so users should be alert in this regard.
