What are the causes of aortic insufficiency

summary

Failure of any one of the factors in the aortic sinus, aortic leaflet, valvular junction and aortic sinus junction leads to poor closure of the aortic leaflet during diastolic period. The size of left ventricular chamber and the function of left ventricle are still the main influencing factors of late curative effect after aortic regurgitation. So what are the causes of aortic insufficiency.

What are the causes of aortic insufficiency

Patients can choose surgical treatment, prosthetic valve replacement is the main treatment of aortic insufficiency, should be performed before the symptoms of heart failure. Arrhythmia and infection should be prevented and treated actively. Penicillin should be given to the patients with aortoarteritis. Streptococcal infection, rheumatic activity and infective endocarditis should be prevented in patients with rheumatic heart disease.

Patients must understand that this disease is due to the diastolic pressure in the left ventricle is much lower than the aorta, a large amount of blood flow back to the left ventricle, which aggravates the diastolic load of the left ventricle, normal left atrial reflux and abnormal aortic reflux, the left ventricular end diastolic volume gradually increases, and the end diastolic pressure can be normal; Due to the decrease of resistance in the aorta due to blood reflux,

Patients must know that this disease is acute aortic regurgitation, which is more common in infective endocarditis. Aortic regurgitation can be caused by the valve damaged by infection, perforation of valve leaflet, incomplete closure of valve leaflet due to vegetations, scar and contracture after inflammation healing, or degeneration and prolapse of valve leaflet. Aortic regurgitation caused by trauma is rare. It can occur after aortic valve stenosis separation or valve replacement. It can also be caused by non penetrating ascending aortic tear caused by trauma.

matters needing attention

Patients must avoid excessive physical labor and strenuous exercise, limit sodium intake, use digitalis drugs, diuretics and vasodilators, especially angiotensin-converting enzyme inhibitors, help to prevent the deterioration of heart function.
