Observational study in 32 patients (30 analyzed) scheduled for aortic valve replacement due to severe aortic stenosis. After induction of anesthesia and before start of surgery, hemodynamic registrations for 1min were obtained before and after a fluid load. Agreement between stroke volume measured by oesophageal Doppler (SVOD) and Vigileo (SVVig) was evaluated in Bland-Altman plot and trending in four-quadrant and polar plots. Bias±limits of agreement (LOA) between SVOD and SVVig was 24±37ml (percentage error 45%). Concordance of the two methods from before to after a fluid load was 100%. Angular bias±LOA was 12°±28°. Absolute values of SVOD and SVVig agreed poorly, but changes were highly concordant during fluid loads in aortic stenosis patients. The angular agreement indicated acceptable trending. The two measurement methods are not interchangeable in patients with aortic stenosis.
