Intraoperative TEE during implantation of a left ventricular assist device (LVAD) is useful for: A. Exclusion of mitral regurgitation, which makes the LVAD ineffective. B. Deciding on location of the inflow cannula into the left ventricle. C. Exclusion of aortic regurgitation that causes a shunt to return back to the left ventricular (LV) cannula. D. Quantitation of tricuspid regurgitation (TR) that affects the amount of right atrial (RA) hypertension. E. Diagnosis of LV enlargement, which is necessary for allowing a large-enough outflow cannula size.
