Figure 152b * a) Inflation of the balloon during
diastole (= augmentation of the aortic diastolic pressure) increases
coronary blood flow ( DPTI ). Schematic representation of coronary blood flow, aortic and left ventricular pressure wave form with / without IABP. (Effects on DPTI and TTI . Balloon inflation during diastole augments diastolic pressure and increases coronary perfusion pressure as well as improving the relationship between myocardial oxygen supply and demand (DPTI:TTI ratio) |
