Introduction
There has been reports on suboptimal LVAD inflow cannula angle and position can cause LVAD pump dysfunction. The purpose of this study is to investigate if the different inflow cannula angle and position affects blood flow pattern inside LV which can potentially contribute to LVAD dysfunction.
Method
We will compare blood flow pattern inside LV under different inflow cannula angles to mitral valve. Also we will be utilizing deidentified imaging data to characterize the flow pattern difference between patients who developed LVAD dysfunction and patients who didn't develop LVAD dysfunction.
