My SO worked at a school where there was a student who attended school for 6 months with a LVAD device. As described it was a backpack powered device and the student was able to attend school normally. My SO was an employee at the school and was trained to be able to provide assistance if needed to the student. The student later received a heart transplant and no longer needed the LVAD device. Unfortunately they died approximately 5-6 years after the transplant.
