“…The variation of aortic root diameters found in the population-based HCHS study correlates well with the so far published studies of similar design [6][7][8][18][19][20][21][22][23][24][25]. Previous studies revealed a marked heterogeneity of aortic root diameters that varied significantly depending on sex, age, and BSA.…”

Here we generate up-to-date reference values of transthoracic echocardiographic aortic root dimensions matched by sex, age, and body surface area (BSA) derived from the population-based Hamburg City Health Study (HCHS) cohort. In 1687 healthy subjects (mean age 57.1 ± 7.7, 681 male and 1006 female), derived from the first prospectively-recruited 10,000 HCHS participants, dimensions of the aortic root were measured in systole and diastole using state-of-the-art 2-dimensional transthoracic echocardiography. Diameters were assessed at four levels: aortic annulus, Sinus of Valsalva, sinotubular junction, and ascending aorta. Female sex was associated with significantly smaller absolute aortic root dimensions, while indexing for BSA resulted in a reverse effect at all levels. There was a strong age dependency of all aortic root diameters as well as aortic annulus/sinotubular junction ratio for both sexes. Multivariate analysis revealed age, sex, weight, height, and BSA to be significant determinants of aortic root size. Finally, formulas were generated for the calculation of individual aortic root reference values considering age, sex, weight, and height. We provide population-based reference values of aortic root diameters based on a standardized transthoracic echocardiographic protocol of the population-based HCHS which may support the diagnosis, monitoring, and treatment of aortic root disease.

“…These results were confirmed by other authors [15,18]. Most studies comparing the various methods used to assess aortic dimensions with 2D TTE in healthy individuals showed that the L-L convention yielded larger dimensions than the I-I convention [6][7][8]11]. Several authors justify the use of the L-L convention by TTE owing to the worse axial resolution of harmonic 2D-TTE compared to CT and CMR.…”

“…These recommendations generated significant controversy in aorta measurements. Several echocardiographic studies reported their results of measuring aortic root and ascending aorta diameters by the I-I edge in diastole [10] in an attempt to be consistent with other vascular imaging modalities (CT and CMR) and increase the intermodality comparison of aorta measurements [11][12][13]. In addition, normal aortic root values were reported by this I-I edge convention measured in end-diastole [6,7,13,14].…”

Ascending aorta diameters have important clinical value in the diagnosis, follow-up, and surgical indication of many aortic diseases. However, there is no uniformity among experts regarding ascending aorta diameter quantification by echocardiography. The aim of this study was to compare maximum aortic root and ascending aorta diameters determined by the diastolic leading edge (DLE) and the systolic inner edge (SIE) conventions in adult and pediatric patients with inherited cardiovascular diseases. Transthoracic echocardiograms were performed in 328 consecutive patients (260 adults and 68 children). Aorta diameters were measured twice at the root and ascending aorta by the DLE convention following the 2015 American Society of Echocardiography (ASE) adult guidelines and the SIE convention following the 2010 ASE pediatric guidelines. Comparison of the diameters measured by the two conventions in the overall population showed a non-significant underestimation of the diameter measured by the SIE convention at root level of 0.28 mm (CI −1.36; 1.93) and at tubular ascending aorta level of 0.17 mm (CI −1.69; 2.03). Intraobserver and interobserver variability were excellent. Maximum aorta diameter measured by the leading edge convention in end-diastole and the inner edge convention in mid-systole had similar values to a mild non-significant underestimation of the inner-to-inner method that permits them to be interchangeable when used in clinical practice.

“…Some guidelines, therefore, continued to use this convention 1,13 but incorporated the use of I-I convention. 1 Many recent publications present both conventions 3,10,14 or prefer to use the I-I convention. 8 Intra-and interobserver variability of measurements are similar using either L-L or I-I convention.…”

Normal values of proximal aorta diameters in healthy Sub Saharan Africans: The TAHES study

et al. 2022

Objectives Reported ranges of normal values are mostly issued from studies performed with Caucasians. This study is a part of TAHES, a population‐based prospective cohort study in Benin and aims to establish normal reference values for echocardiographic diameters of the proximal aorta in Africans. Methods Transthoracic echocardiography (TTE) examinations were performed by four cardiologists following pre‐defined protocols, and analyzed off‐line by a single observer. Aortic root diameters were measured during diastole for sinuses of Vasalva (SV), sinotubular junction (STJ) and proximal ascending aorta (AA), and during systole for annulus. Upper limits were defined as the 95th percentiles. Results We included 513 normotensive, non‐diabetic, and cardiovascular disease‐free individuals (206 men, 307 women, age 40 ± 14 years). The diameters of the proximal aorta were significantly greater in men. The inner‐edge‐to‐inner‐edge non‐indexed upper values for the annulus, SV, STJ and AA were respectively 25, 34, 28.5, 32 mm in men and 22, 30, 26, 30 mm in women. The leading‐edge‐to‐leading‐edge upper values were respectively 38, 35, 36 for men and 34, 33, 32 mm for women. No significant differences between sexes were recorded for body surface area (BSA)‐indexed diameters of the annulus, STJ and AA. BSA‐indexed SV dimension was greater in men than women were. SV, STJ, AA indexed‐diameters correlated with age in both sexes but not for annulus indexed‐diameter. Conclusion Normal values from a general population in West Africa could to differ from those established in Caucasian populations. Ethnic‐specific reference diameters are here proposed for appropriate diagnosis of proximal aortic diseases in sub‐Saharan Africa.
