2). Cardiac catheterization measures an invasive ∆P that progressively decreases as the site of the catheter placement in the aorta moves downstream from the vena contracta, where the pressure measured is partially recovered, until the extent of Prec has reached its plateau, at which ∆Pnet is achieved. Utilizing a catheter placed in the LV and another placed in the femoral artery will lead to an overestimation of the true ∆Pnet due to the delay that occurs in pressure transmission from the proximal aorta to the femoral artery and should not be used.
