Apicoaortic bypass has double outlets and its graft design is similar to that of a left ventricular assist device (LVAD).
This study aimed to evaluate the graft designs of apicoaortic bypass and their effects on flow distribution and energy loss (EL).
The result that the regional blood flow distribution was different, but the trend of the EL which increased inversely with the CO through the AsAo was similar between the LV-DsAo(left ventricular apex to the descending aorta) and LV-AsAo(left ventricular apex to the ascending aorta) bypasses.
