Assessment of aortic root dimensions. The measurements should be obtained using the inner-edge to inner-edge methodology in end diastole (defined as the onset of the QRS). Measurements should be obtained at three levels including: sinus of Valsalva (red line); sino-tubular junction (green line); proximal ascending aorta defined as the region 1 cm above the sino-tubular junction (blue line). If there is enlargement above this level the maximal dimension should be measured and stated in report. Measurements should be reported after indexing for height.
