Regurgitation is due to incompetence of the aortic valve or any disturbance of the valvular apparatus (eg, leaflets, annulus of the aorta) resulting in the diastolic flow of blood into the left ventricular chamber. Calcification occurs in atherosclerotic vascular lesions and in the aortic valve.

If the aortic valve doesn’t open all the way, it gets harder to pump blood. Degeneration occurs in conjunction with an accumulation of dermatan sulfate, a glycosaminoglycan, within the connective tissue matrix of the valve but the exact mechanism is not.

Aortic stenosis (as) may be defined as narrowing of the aortic valve, due primarily to a combination of progressive fibrosis and calcification of the matrix, with consequent increase in valve stiffness, progressive reductions in valve area and concomitant increases in left ventricular afterload and work. The aortic valve helps keep blood.

Aortic Valve Replacement (Avr) Remains One Of The Most Commonly Performed Procedures In Cardiac Surgery.

Sclerosis and calcific aortic valve disease have led to the hypothesis that calcific aortic valve disease is primarily a manifestation of atherosclerosis.38,44 however, there also are dissimilarities in these disease processes that may suggest a more complicated picture. As is the most frequent form and accounts for the majority of congenital forms and for all of the acquired forms. Mechanical stress or injury on the aortic valve along with other atherosclerotic risk factors causes valvular endothelial dysfunction.

Biological Processes Implicated In Aortic Valve Lesion Pathogenesis

If the aortic valve doesn’t open all the way, it gets harder to pump blood. Proper functioning of this valve is critical in maintaining efficient cardiac function. Calcific aortic valve disease (cavd) is a slow, progressive disorder that ranges from mild valve thickening without obstruction of blood flow, termed aortic sclerosis, to severe calcification with impaired leaflet motion, termed aortic stenosis.

Aortic Valve Stenosis Is A Common Problem Among The Elderly, And Valve Replacement Is Still The Only Treatment Option For Severe Symptomatic Disease.
