Figure 2 Anatomical Analysis of the Aortic Root

The anatomy of the aortic root was assessed on 3 reconstructed views. The coronal view (A) is similar to the anterior-posterior view on aortic root angiography. The reconstructed single oblique sagittal (B) view has the same orientation as the parasternal long-axis view on transthoracic echocardiogram and the mid-esophageal long-axis view on transesophageal echocardiogram. The reconstructed double oblique transverse view (C) is parallel to the plane of the aortic root. See Table 1 for detailed description of the variables.
