Stenosis of the Aortic Estuary Relative (Stenosis Ostii Aortae Relativa)

“Relative aortic stenosis” (stenosis ostii aortae relativa) is a combination of the normal diameter of the aortic opening with a pathological expansion of the ascending section (for example, with its aneurysm).

This condition is characterized by the fact that with the normal size of the aortic opening, expansion of the ascending aorta occurs. This leads to a functional narrowing of the relatively enlarged aortic lumen, despite the normal absolute diameter of the aortic opening.

The cause of “relative aortic ostium” stenosis is most often an aneurysm of the ascending aorta. Enlargement of the aortic lumen above the aortic valve creates hemodynamic disturbances similar to true aortic stenosis. This leads to increased pressure in the left ventricle and myocardial hypertrophy.

Diagnosis of relative aortic stenosis is based on visualization of dilation of the ascending aorta with a normal valve opening. Treatment is aimed at correcting the aneurysm and preventing its complications.



Aortic stenosis: a relatively rare disease. Stenosis is a narrowing of the lumen of a relatively healthy aortic trunk. In this case, stenosis occurs at the mouth of the most important artery, the aorta.

Stenosis is a manifestation of much more serious diseases:

1. Dilation of the ascending aorta - if there is a dilation or stretching of a certain part of the aorta, then an increase in the size of the valve may occur, which will lead to stenosis of the orifice, since it will consist of a dilated blood vessel. Further, this can lead to restricted blood flow. 2. The outcome of atherosclerosis - the result of this disease is damage to the walls of the aorta and even its walls. This can lead to the formation of plaques in the first place, which will harden over time and then block normal blood flow. 3. Rheumatoid arthritis is a chronic non-infectious disease, the main problem of which is inflammation of the connective tissue, which ultimately leads to joint deformation. 4. Systemic lupus erythematosus is a heterogeneous group of polyetiological diseases related to systemic autoimmune connective tissue diseases of unknown etiology and characterized by a pronounced inflammatory reaction of the skin and various organs and systems. 5. Obliterating atherosclerosis – occurs when blood vessels are damaged of any etiology.
