Aortic diameters were independently associated with age, gender (model A), and BSA (model B); weight and height did not have any additional significant impact on aortic dimension (model C; Table6 ). Aortic Root Colored area represents upper and lower limits of normal, with the equation for the former (ULN) shown below each plot. You're still going to find the same useful information here. The aim of this study was to explore the full spectrum. Among patients with thoracic ascending aortic aneurysm (TAAA), how does aortic diameter indexed to patient height (the aortic height index [AHI]) compare with aortic diameter indexed to body surface area (BSA) for the estimation of the risk of aortic dissection, rupture, or death? Left ventricular (LV) mass was calculated by the Penn convention and indexed for BSA. Principally, the Society wanted to ensure that reference intervals were derived from the most contemporaneous and prospectively acquired data; that reference intervals were derived from evidence that best applies to the British population; and finally that echo guidance and cut-offs reflect UK practice. The aortic root is located between the aortic annulus (the junction of the outflow tract of the left ventricle and the aortic valve) and the sinotubular junction (where the ascending aorta originates).
