(a) Aortic pressure waveforms before and after cardiopulmonary bypass of a patient undergoing coronary artery bypass graft surgery. End-systolic pressures, defined as dicrotic notch pressure, make up different percentages of systolic arterial pressure in these situations, leading to erronous estimates of (single-beat) Ees when assuming Pes = 0.9 × systolic arterial pressure (b).
