The patient was implanted with a left ventricular assist device (lvad) on (b)(6) 2017.It was reported that the pump was making abnormal noises.On (b)(6) 2018, sporadic low flow events were observed that correlated with a metallic noise coming from the pump.Ct showed was unremarkable for outflow graft kinking or obstruction due to positional changes.On (b)(6) 2018, the pump was making noises with positional changes.Imaging in the catheterization laboratory with lv gram revealed patient had good flow through the inflow and outflow when lying flat on the back.When lying on the left lateral side, vad parameters changed, and imaging revealed dynamic inflow obstruction with septal tissue moving laterally impinging on the inflow graft resulting in substantially reduced flow in the outflow graft.Due to this, the decision was made to increase blood pressure, promote right to left throughput, and maintain adequate volume.The patient has been discharged.No additional information was provided.
