Intra Aortic Balloon Pumping (IABP) have widely been employed as a mechanical support for card.iogenic shock.
However, insertion of intra aortic balloon through the femoral artery may be difficult for the patient who have obstructive aort-iliac atherosclerotic lesion.
we introduced new method for such patient, our circuit system consists of a Pulsatile Assist Device (PAD) with two ball-Valves at its inlet and outlet, Hemodynamic effect of V-A bypass pumping method using this device was already reported.
we applied this device for left heart bypass pumping method. Blood was drained from left atrium and infused only diastolie period from femoral artery. The flow was converted into pulsatile flow through PAD driven by Datascope System 80.
Data were as follows.
Aortic mean systolic pressure decreased 12.6±33%, Tension Time Index decreased 13.5±3.1% and Cardiac output decreased 35±6.3%. on the other hand, Mean aortic pressure increased 10.6±3.9% and Total Perfusion Flow increased 12.8±6.8%.
