Purpose The fourth-generation FloTrac/Vigileo™ improved its algorithm to follow changes in systemic vascular resistance index (SVRI). This revision may improve the accuracy and trending ability of CI even in patients who undergo abdominal aortic aneurysm (AAA) surgery which cause drastic change of SVRI by aortic clamping. The purpose of this study is to elucidate the accuracy and trending ability of the fourth-generation FloTrac/Vigileo™ in patients with AAA surgery by comparing the FloTrac/Vigileo™-derived CI (CI ) with that measured by three-dimensional echocardiography (CI ). FT 3D Methods Twenty-six patients undergoing elective AAA surgery were included in this study. CI and CI3 were determined FT D simultaneously in eight points including before and after aortic clamp. We used CI as the reference method. 3D Results In the Bland–Altman analysis, CI had a wide limit of agreement with CI showing a percentage error of 46.7%. FT 3D Subgroup analysis showed that the percentage error between C O and CO was 56.3% in patients with cardiac index < 2.5 3D FT 2 2 L/min/m and 28.4% in patients with cardiac index ≥ 2.5 L/min/m . SVRI was significantly higher in patients with cardiac index < 2.5 L/min/m (1703 ± 330 vs. 2757 ±
