“…In our study, blood pressure increase in the control group was mild (20%), but in expected levels when aortic cross-clamping is performed 3,7,15 , followed by increase in right atrium, pulmonary artery and pulmonary wedge pressures, cardiac and systolic indices, and right and left ventricle systolic work. Several authors have observed filling pressure increase during aortic cross-clamping 7, 15,16 , while others have not observed such changes 8 . In our study, hemodynamic response during aortic cross-clamping may be explained by blood volume redistribution.…”
