Figure 2 Native Aortic Root on MSCT
The axial plane of the native aortic valve on multislice computed tomography (MSCT) and corresponding orientation of an anatomical specimen. The most caudal attachment of all 3 aortic leaflets can be seen in one axial image. The anatomical image is from W.A. Mcalpine. Heart and Coronary Arteries: An Anatomical Atlas for Clinical Diagnosis, Radiological Investigation, and Surgical Treatment. Springer Verlag; October 1974. LAFT = left anterior fibrous trigone; LCA = left coronary artery; RAFT = right anterior fibrous trigone; RCA = right coronary artery; TV = tricuspid valve.

Figure 3 Levels of Measurement of the CRS on MSCT
The appearance of the CRS is shown on MSCT (coronal cut plane) after implantation and levels (1, 2, 3, 4) where the dimensions were measured. CRS = CoreValve ReValving System; MSCT = multislice computed tomography.

Figure 4 Axial Morphology of the CRS
The morphology of the CRS at the levels of interest (1, 2, 3) in 3 patients, where the position within the aortic root was close to the median, lower, or higher. CRS = CoreValve ReValving System.
