The normal values for the internal diameter of the aortic root are 33-36 mm in men and 28-32 mm in women, with values below normal called aortic constriction and above normal called aortic dilatation. Generally greater than 45 mm is called aneurysmal dilatation, a significant widening of the aortic root and a consequent increased risk of aortic coarctation. Aortic coarctation can occur at any time if the aortic internal diameter is greater than 55 mm, and aortic CTA is recommended to further clarify the diagnosis. Patients with aortic aneurysmal dilatation must have strict blood pressure and heart rate control, keeping blood pressure around 110/60 mmHg and heart rate around 60 beats per minute. The specific medication used to control blood pressure and heart rate can be consulted with a cardiologist, and under the guidance of the doctor, the medication should be used strictly in accordance with medical advice and should be reviewed regularly.
