Demographics and clinical characteristics, LV dimensions, and aortic diameters, both absolute and relative to BSA, are presented as mean SD and were tested by unpaired t test to evaluate differences between genders. We report a modest increase in aortic size with both increased BSA and age across males and females. Stay tuned! Last, differences in aortic dimensions were also observed according to race: Asians had the smallest nonindexed aortic dimensions at all levels. The Bland-Altman analysis gave a 95% confidence interval of 4.1 1.1% for the aortic annulus, 3.9 1.1% for the sinuses of Valsalva, 4.1 1.1% for the sinotubular junction, and 4.8 1.3% for the maximum diameter of the proximal ascending aorta. Copyright 2000-2023 JLS Interactive, LLC. Three models were developed in multiple regression analysis to explain aortic dimensions. However, weight might not contribute substantially to aortic size and growth. Valvular regurgitation was quantified from color Doppler imaging and categorized as absent, minimal (within normal limits), mild, moderate, or severe. 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). Diagnosis and Surveillance of Aortic Root Dilation | IntechOpen The Gorlin equation. 10, 11 Therefore, BSA may be used to predict aortic root diameter in several age intervals. Aortic dimensions were expressed as mean, median, and twenty-fifth and seventy-fifth percentiles; the aortic dimension above the ninety-fifth percentile of the overall distribution was used as cutoff for the upper limit. Three BP measurements were obtained from the right arm with a mercury manometer, and the results were averaged to determine systolic and diastolic BPs. Cut-off values for severe stenosis are <1.0 cm2 for AVA and <0.6 cm2/m2 for AVAindex. Ascending Aorta: Anatomy and Function - Cleveland Clinic Aortic Root, indexed: (cm/m 2) Discriminant Score: .

So I just had a "New Year, New Me" moment and my resolution is to become a new and improved version of myself in a couple of weeks. The rationale for all suggested changes to practice are discussed in the guideline document. 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. From: 2010 ACCF/AHA/AATS/ACR/ASA/SCA/SCAI/SIR/STS/SVM, A formula to estimate the approximate surface area if height and weight be known, = 0.0235 x height (cm) 0.42246 x weight (kg) 0.51456, =square root (( height (cm) x weight (kg))/ 3600). Aorta dimensions are variably dependent on age, gender, and body size. Background: To account for differences in body size in patients with aortic stenosis, aortic valve area (AVA) is divided by body surface area (BSA) to calculate indexed AVA (AVAindex). Annulo-aortic ectasia is a combination of: 1) ascending aortic aneurysm 2) dilatation of the sinuses of Valsalva and 3) dilatation of the aortic annulus. There are significant differences in aortic dimensions according to sex, age, and race.

Aortic Size Assessment by Noncontrast Cardiac Computed Tomography: Normal Limits by Age, Gender, and Body Surface Area. 2019 Jun 15;123(12):2015-2021. doi: 10.1016/j.amjcard.2019.03.013. Current guidelines recommend prophylactic surgical intervention at an aortic diameter of 5.5 cm for asymptomatic patients, and between 4.0 and 5.0 cm for Marfan syndrome and other genetically-mediated thoracic aortic aneurysms (TAAs) ( 2 ). 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). The function of the normal sinuses is to prevent occlusion of the coronary artery ostia during systole when the aortic valve opens. The normal sinus diameter is less than 4.0 cm for men and 3.6 cm for women.
