Background. Interventions on the aortic root require morphometric analysis of the ascending aorta and the coronary arteries. Carrying out the transcatheter aortic valve implantation (TAVI) involves measuring the height of the origin of the coronary arteries. Objective. Measure the height of the right and left coronary arteries in men without any structural changes of the aortic root and the coronary arteries; assess the interdependence of the height and anthropometric indicators. Methods. The participants of the study underwent chest computed tomography angiography and morphometric analysis of the height of the origin of the coronary arteries. Statistical analysis was performed according to Student’s t-test and Pearson’s linear correlation method (observed variables: age, height, body weight, body mass index and body surface area). Results. In men, under conditions of physiological norm, the height of the left coronary artery ostium was 15.33±3.73 mm; the average height of the right coronary artery ostium was 16.67±3.69 mm. When the height of the ostia was compared among the subgroups formed by height, an increase in height of the ostia was linked to the increase in height (p < 0.05). The correlation (direct, medium) between the height of the ostia of the right and left coronary arteries and the height parameter was observed: r = + 0.61 (p ˂ 0.001) and r = + 0.30 (p = 0.05), respectively. There is no proven correlation with age, weight, body mass index, body surface area and height of the coronary artery ostia (p ˃ 0.05). Conclusion. With increasing height in men, the height of the right and left coronary arteries ostia increases. Having analyzed the anthropometric indicators, the correlation of the men’s height with the height of the coronary artery ostia has been confirmed.
