Figure 2 Bland-Altman Plot Illustrating the Difference Between the Aortic Annular Dimension Determined by TTE and TEE

Important differences may exist between aortic annulus size as determined by either TTE or TEE. The red circles indicate larger dimensions by TTE; the black circles indicate agreement; the green circles indicate larger dimensions by TEE. Annular dimension was determined by TTE before PHV implantation and TEE dimension at time of implantation. Abbreviations as in Figures 1 and 4.
