Figure 1
Representative 3-dimensional computed tomography images showing how the aorta-left atrium angle (A), aorta-left ventricle angle (B), diameter of coronary cusp, distance from coronary cusp to atrium (C) are measured. Ao = ascending aorta; LA = left atrium; LCC = left coronary cusp; LV = left ventricle; LVZ = low-voltage zone; NCC = non-coronary cusp; RCC = right coronary cusp.
