A balloon <br /> catheter is placed thru the femoral artery (usually) into the descending <br /> aorta and its inflation is synchronized with the heartbeat via attached <br /> EKG leads... when the heart is in diastole (ventricles filling) the <br /> balloon inflates, thus causing an increase in pressure in the aorta and <br /> pushing blood backwards under higher-than-normal-diastolic pressure into <br /> the coronary arteries (the coronaries fill during diastole normally; this <br /> gives them more flow). The balloon then deflates just before systole <br /> (ventricles contacting) so they have much less resistance to push against <br /> in the aorta, which decreases their workload.  You can probably see how <br /> these two effects are beneficial for a failing heart. <br /> Don't know if that's what you're asking about, though... <br /> best <br /> wendie <br /> </p> Are you perhaps thinking of an intraaortic balloon pump?
