The Effect of Spiral Inducing Chamber to Left Ventricular Assist Device Outflow Cannula

The rise of heart failure in the setting shortage donor had brought to emergence development left ventricular assist device (LVAD). However, patients are still encountering severe complications such as stroke and thrombosis due hemodynamic changes. This study aimed compare characteristic between standard spiral LVAD outflow cannula. Two different anastomosis sites (2cm 3cm) from sino-tubular junction used a inducing chamber is attached cannula promote flow. result showed that exhibit lower output velocity with 37% percentage difference region low WSS value.
