Top: Bland-Altman of % Difference Between Measured Aortic and Caval Flow. Note good agreement with the exception of 4 outliers, but with a bias of the aorta being 21% greater. The difference is not a function of cardiac output. Bottom: Total Caval Flow and Pulmonary Flow vs. Aortic Flow with outliers not included. Caval flow demonstrates strong correlation with aortic flow data, y=0.83x+0.11, r=0.90. Similarly, pulmonary flow demonstrates strong correlation with aortic flow (r=0.85).
