LEFT ATRIAL APPENDAGE INVERSION PRESENTING AS ACUTE RIGHT VENTRICULAR FAILURE AFTER LEFT VENTRICULAR ASSIST DEVICE IMPLANTATION

•Inversion of the LAA is very rare and is associated with negative intracardiac pressure.•High LVAD speeds induce negative intracardiac pressure and can cause LAA inversion.•LAA inversion can lead to mitral valve outflow obstruction and RV failure.•This has the potential to be a catastrophic complication after LVAD implantation.
