Figure 1 Number of subjects at each measured annular diameter (n = 66). The Journal of Thoracic and Cardiovascular Surgery 2007 134, 1526-1532DOI: (10.1016/j.jtcvs.2007.07.046) Copyright © 2007 The American Association for Thoracic Surgery Terms and Conditions

Figure 2 Mean deviation of number label from measured annular diameter with standard deviation error bars in 5 mechanical valves (top) and 3 stented tissue valves (bottom). Asterisks indicate statistically significant deviation from the number label compared with the measured annular diameter (n = 66).

Figure 3 Regression analysis for the 3 different valve types: bioprosthetic, supra-annular mechanical, and intra-annular mechanical aortic valves (n = 66). Measured annular area is the largest standard sizer that could fit into the annulus (in square centimeters). Corresponding annular diameter is the diameter of this sizer in millimeters.

Figure 4 Relationship between the geometric orifice area and measured annular area in 3 stented bioprosthetic valves. Lines depict regression analysis (n = 66). Measured annular area is the largest standard sizer that could fit into the annulus (in square centimeters). Corresponding annular diameter is the diameter of this sizer in millimeters.
