Abstract :In this study, we aimed to determine the normal distribution ranges of aortic elasticity parameters produced from data obtained from ascending aortic diameters according to age and sex and to analyze the factors affecting aortic elasticity parameters. Patients were grouped according to age and sex. In addition to the demographic data of all patients, the left ventricular systolic and diastolic functions, aortic diameters, and left ventricular masses were evaluated using transthoracic echocardiography. The aortic diameters, aortic strain, aortic stiffness, and aortic distensibility were obtained. A total of 215 patients (103 boys and 112 girls) were included in our study. In the study, the mean values of age and body surface area (BSA) were 8.49 (±5.37) years and 1.02 (±0.46) m2, respectively. The aortic strain, stiffness, and distensibility values were 23.13% (±16.03), 3.33 (±1.95), and 0.010 (±0.008) dyn-1*cm2*10-6, respectively. When compared according to sex, age, left ventricular function, aortic diameter, and aortic elasticity parameters were similar. A table of normal value ranges of aortic elasticity parameters was created according to age group and sex. There were varying degrees of correlations between aortic elasticity parameters and age, BSA, left ventricular function, aortic diameter, and blood pressure. The aortic elasticity parameters vary according to age and sex. Aortic elasticity parameters are affected by age, heart function, aortic diameter, blood pressure, and hormonal status, which change during puberty.
