In this study, the authors found that a simpler measure of aortic diameter indexed to height had similar predictive power compared to aortic diameter indexed to BSA. Transthoracic echocardiographic reference values of the aortic root: results from the Hamburg City Health Study. Example of 2D echocardiographic measurements of aortic dimensions at the level of the aortic annulus (A), sinuses of Valsalva (B) and sinotubular junction (C). Two-dimensional measurements of the AR were made at end-diastole in parasternal long-axis views at 4 levels: (1) annulus (defined echocardiographically as the hinge points of the aortic cusps), (2) sinuses of Valsalva, (3) sinotubular junction, and (4) proximal ascending aorta. doi: 10.1530/ERP-20-0035. Aortic dimensions were larger in older age groups in both sexes, a trend that persisted regardless of BSA or height adjustment. The reported ranges of aortic root diameters are limited by small sample size, different mesurements sites, and heterogeneous cohorts. Would you like email updates of new search results? (PDF) Sex-specific Morphometric Analysis of Ascending Aorta and Aortic Aortic root diameter was strongly related to BSA and height (r = 0.48 for the 2 comparisons), age (r = 0.36), and male gender (+2.7 mm adjusted for BSA and age, p <0.001 for all comparisons). 2021 Apr 28;8(1):G19-G59. Raw data was not published; the normality of the sizes within the raw data therefore could not be verified. 1.

Two-dimensional measurements of the AR were made at end-diastole in parasternal long-axis views at 4 levels: (1) annulus (defined echocardiographically as the hinge points of the aortic cusps), (2) sinuses of Valsalva, (3) sinotubular junction, and (4) proximal ascending aorta. 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. Based on these results, an aortic diameter-to-patient height ratio of 2.43 cm/m indicates lower risk, 2.44-3.17 cm/m indicates moderate risk warranting close radiographic follow-up, 3.21-4.06 cm/m indicates high risk, and 4.1 cm/m represents severe risk. PDF Aortic Size Assessment by Noncontrast Cardiac Computed Tomography Gender differences are then accounted for by indexing the volume to body surface area (BSA) via the Mosteller equation. Normal Values of Aortic Root Size According to Age, Sex, and Race This group previously published data that used aortic diameter indexed to BSA as a more patient-specific predictor of risk. An aneurysm is a weak spot in a blood vessel wall. The five images were obtained from a single patient: SoV (Sin us of Valsalva), Asc (ascending aorta), Arch (aortic arch), pDTA (proximal descending thoracic aorta), and dDTA (distal descending thoracic aorta). Please quote your membership Indexing of aortic root diameters to BSA had a reverse effect and revealed significantly larger aortic root diameters for women (Table 2 ). The aortic size index (ASI) is defined as the AD divided by BSA. The interobserver and intraobserver variabilities were examined using both Pearson bivariate 2-tailed correlations and Bland-Altman analysis. Growth rate estimates, yearly complication rates, and survival were assessed. . Patients were stratified into four categories of yearly risk of complications based on ASI and AHI.
