Data analysis was performed using SYSTAT, version 12 (University of Illinois, Chicago, Illinois). The .gov means its official. The sinuses of Valsalva and sinotubular junction were measured at end-diastole using leading edge to leading edge technique. BSA-indexed AR diameters stratified by age decades and gender are reported in Table4 . BSA was calculated according to the DuBois formula [0.20247 height (m) 0.725 weight (kg) 0.425]. Keywords: 2022 Mar;35(3):275-277. doi: 10.1016/j.echo.2021.12.001. Gender differences are then accounted for by indexing the volume to body surface area (BSA) via the Mosteller equation. Diagnosis and Surveillance of Aortic Root Dilation | IntechOpen Indexing AVA by BSA (AVAindex) significantly increases the prevalence of patients with criteria for severe stenosis by including patients with a milder degree of the disease without improving the predictive accuracy for aortic valve related events. The aim of the present study was to assess the potential differences in aortic root measurements when aortic root Z-scores were obtained in a cohort of paediatric Marfan patients using several published nomograms.

Cut-off values for severe stenosis are <1.0 cm 2 for AVA and <0.6 cm 2 /m 2 for AVA index. The intraobserver variability analysis revealed Pearson correlations as follows: r= 0.90 (p <0.0001) for the aortic annulus, r= 0.97 (p <0.0001) for the sinuses of Valsalva, r= 0.96 (p <0.0001) for the sinotubular junction, and r= 0.86 (p <0.0001) for the maximum diameter of the proximal ascending aorta. It is recommended that the changes suggested within the guideline should be discussed with sonographers, cardiologists and general clinicians when integrating the new reference intervals into everyday practice to ensure a smooth transition in the care of patients. Enter the height, weight, and age and select the correct units. 2008;1(2):200-209. Adjustment for height and weight in the regression models avoided the assumption made in indexing to certain parameter of body size (e.g., BSA), while achieving the same purpose of accounting for differences in body size among participants. The https:// ensures that you are connecting to the Our final study population therefore consisted of 1,043 healthy subjects (mean age 44.7 15.9years, range 16 to 92years, 503 men [48%]). In 1,207 apparently normal subjects 15 years old (54% women), aortic root diameter was 2.1 to 4.3 cm. The Gorlin equation. Aortic root dilation (AoD) is frequently an incidentally discovered, asymptomatic finding in that is seen on various imaging modalities [].The anatomy of the aortic root includes the annulus, sinuses of Valsalva, sinotubular junction and ascending aorta [], with the size being a function of a patient's biologic variables such as height, age, BSA, and gender [1, 2].
