FIELD: medicine.
SUBSTANCE: calculation of the required diameter of the aortic root in persons aged 15-65 years is carried out according to the formula: ARRD = 1.925+0.009 × age + 0.574 × BSA - 0.193 × sex (1), where ARRD is the required diameter of the aortic root (mm), age is the patient's age (years), BSA is body surface area (m2), sex of the patient is 1 for men, 2 for women. At that, for a normal diameter of the aortic root, any digital value within ±0.44 cm from the calculated ARRD is accepted.
EFFECT: method allows to obtain patient-specific values for the aortic root diameter and to determine the deviation of the actual values of the index obtained during echocardiography from the physiological norm by taking into account individual anthropometric indices using a mathematical formula.
