Abstract Aims Accurate assessment of aortic dimensions can be achieved using contrast-enhanced computed tomography. The aim of this study was to define normal values and determinants of aortic dimensions throughout multiple key anatomical landmarks of the aorta in healthy individuals from the Copenhagen General Population Study. Methods and results The study group consisted of 902 healthy subjects selected from 3000 adults undergoing cardiovascular thoracic and abdominal computed tomography-angiography (CTA), where systematic measurements of aortic dimensions were performed retrospectively. Individuals included were without any of the following predefined cardiovascular risk factors: (i) self-reported angina pectoris; (ii) hypertension; (iii) hypercholesterolaemia; (iv) taking cardiovascular prescribed medication including diuretics, statins, or aspirin; (v) overweight (defined as body mass index ≥30 kg/m2); (vi) diabetes mellitus (self-reported or blood glucose >8 mmol/L); and (vii) chronic obstructive pulmonary disease. Maximal aortic diameters were measured at seven aortic regions: sinuses of Valsalva, sinotubular junction, ascending aorta, mid-descending aorta, abdominal aorta at the diaphragm, abdominal aorta at the coeliac trunk, and infrarenal abdominal aorta. Median age was 52 years, and 396 (40%) were men. Men had significantly larger aortic diameters at all levels compared with women (P < 0.001). Multivariable analysis revealed that sex, age, and body surface area were associated with increasing aortic dimensions. Conclusion Normal values of maximal aortic dimensions at key aortic anatomical locations by contrast-enhanced CTA have been defined. Age, sex, and body surface area were significantly associated with these measures at all levels of aorta. Aortic dimensions follow an almost identical pattern throughout the vessel regardless of sex.

Abstract We evaluated the feasibility and image quality of prospective electrocardiography (ECG)-triggered coronary computed tomography angiography (CCTA) using a body surface area (BSA) protocol for contrast-medium (CM) administration on both second- and third-generation scanners (Flash and Force CT), without using heart rate control. One-hundred-and-eighty patients with suspected coronary heart disease undergoing CCTA were divided into groups A (BSA protocol for CM on Flash CT), B (body mass index (BMI)-matched patients; BMI protocol for CM on Flash CT), and C (BMI-matched patients; BSA protocol for CM on Force CT). Patient characteristics, quantitative and qualitative measures, and radiation dose were compared between groups A and B, and A and C. Of the 180 patients, 99 were male (median age, 62 years). Average BSA in groups A, B, and C was 1.80 ± 0.17 m2, 1.74 ± 0.16 m2, and 1.64 ± 0.17 m2, respectively, with groups A and C differing significantly (P < 0.001). Contrast volume (50.50 ± 8.57 mL vs. 45.00 ± 6.18 mL) and injection rate (3.90 ± 0.44 mL/s vs. 3.63 ± 0.22 mL/s) differed significantly between groups A and C (P < 0.001). Groups A and C (both: all CT values > 250 HU, average scores > 4) achieved slightly lower diagnostic image quality than group B. The BSA protocol for CM administration was feasible in both Flash and Force CT, and therefore may be valuable in clinical practice.

Expected mean values and a range of normal values (plus or minus two standard deviations) are presented for the vital capacity and the maximum breathing capacity of male children and adolescents. It is recommended that calculations of the above values be based upon four attributes (age, height, weight, and body surface area) rather than upon a prediction deriving from a single attribute (especially in the individual who does not have a standard height and weight for his age).

Abstract Funding Acknowledgements WASE Normal Values Study is sponsored by American Society Echocardiography Foundation. OnBehalf the WASE Investigators Background The American Society of Echocardiography (ASE) and the European Association of Cardiovascular Imaging (EACVI) chamber quantification guidelines provide normal reference values for a variety of size and function parameters. While used worldwide, these were predominantly obtained from American and European Caucasian populations and may not represent individuals from other regions around the world. Accordingly, ASE in collaboration with its International Alliance Partners conducted the World Alliance of Societies of Echocardiography (WASE) Normal Values Study to establish and compare normal echocardiographic values across races, ethnicities and countries worldwide. While most previous studies focused on left ventricular (LV) size and ejection fraction, LV stroke volume (SV) in healthy normal subjects has not been well defined. In this report, we aim to examine similarities and differences in normal LV SV indexed by body surface area (SVI) among regions around the world. Methods WASE Normal Values Study is a multinational, observational, cross-sectional study. Individuals free from known cardiac, lung and renal disease were prospectively enrolled with even distribution among age groups and gender. Echocardiographic images were acquired following a standardized protocol. LV SV was assessed by Doppler-derived (LVOT diameter and VTI) and two-dimensional (2D) biplane Simpson’s methods. LV SVI was calculated to account for differences in body size. These measurements were analyzed (TOMTEC) in a single core laboratory following ASE/EACVI Guidelines. Results As of May 2019, LV SV has been analyzed in 1164 cases from 13 countries, representing 8 distinct regions worldwide. In this population, age, body surface area and 2D LV ejection fraction were 47 ± 17 years old (range 18-87 years old), 1.76 ± 0.22 m² (range 0.95-2.44 m²) and 63.2 ± 2.9 % (range 52.7-73.7 %), respectively. LV SV and SVI by Doppler were larger than those obtained by 2D method in all regions. LV SV and SVI in both methods had significant differences among regions (p&lt; 0.0001, Kruskal-Wallis test). LV SV and SVI in South Asia (India) were smallest in both methods and were also significantly smaller than other Asian regions (Figure). North America and Europe had largest LV SV and SVI by Doppler method, while Oceania had largest values by 2D. Conclusions The WASE Normal Values Study shows geographical variability in LV SVI across continents and countries. This information should be considered when determining normative values for SV and SVI. Abstract P1766 Figure.

Geometric Changes

Abstract BACKGROUND There is conflicting data on early left ventricle (LV) remodeling in diabetes mellitus (DM) and hypertension (HTN). This study examines the feasibility of cardiac computed tomography angiography (CCTA) to detect early LV geometric changes in patients with DM and HTN. METHODS Consecutive patients (n = 5,992) who underwent prospective electrocardiography (ECG)-triggered (mid-diastolic) CCTA were screened. Patients with known structural heart disease or known LV dysfunction were excluded. Left ventricular mass (LVM), left ventricular mid-diastolic volume (LVMDV), and LV concentricity (LVM/LVMDV) were measured and indexed to body surface area. RESULTS A total of 4,283 patients were analyzed (mean age 57 ± 10.69 years, female 46.7%). DM, HTN, and HTN + DM were present in 4.1%, 35.8% and 10.6% of patients, respectively. Compared to normal patients, HTN and HTN + DM patients had increased LVM indexed to body surface area (LVMi) (56.87 ± 17.24, 59.26 ± 13.62, and 58.56 ± 13.09, respectively; P &lt; 0.05). There was no difference in LVMi between normal subjects and patients with DM (56.39 ± 11.50, P = 0.617). Concentricity indices were higher in patient with HTN (1.0456 ± 0.417; P &lt; 0.001), DM (1.109 ± 0.638; P = 0.004), and HTN + DM (1.083 ± 0.311, P &lt; 0.001) than normal individuals (0.9671 ± 0.361). There was no overlap of the 95% confidence intervals in the composite of concentricity indices and LVMi between the different groups. CONCLUSIONS CCTA measures of LVM and concentricity index may discriminate patients with HTN and DM before overt structural heart disease.
