heart aortic regurgitation
Introduction
Introduction The aortic valve between the left ventricle and the aorta is open when the ventricle contracts. The blood flow in the left ventricle enters the aorta and is directed to the whole body. When the ventricle is dilated, it closes, preventing the blood in the aorta from returning to the left ventricle. When aortic regurgitation occurs, the aortic valve cannot be closed tightly during diastole, causing blood to flow from the aorta to the left ventricle. Aortic regurgitation is caused by aortic regurgitation, mostly because of changes in the structure of the inner edge of the valve leaf with atrophy, so that the aortic valve can not be completely closed, so that blood in the systolic phase through the aortic valve mouth by the main The countercurrent phenomenon of the arterial inward ventricle. Therefore, aortic regurgitation is also known as aortic regurgitation. More common in rheumatic heart disease, hypertension and so on.
Cause
Cause
The etiology of aortic regurgitation can be divided into congenital and acquired. Congenitality is very rare, mostly due to a two-valve deformity of the aortic valve, which prevents it from completely closing. Acquired aortic regurgitation is most common in rheumatic heart disease or bacterial endocarditis, and a few can also be seen in syphilis or degenerative changes, such as cystic necrosis of the middle vascular layer, or aortic sclerosis. The ratio of male to female is 3:1. About 10% of patients with mitral valve disease.

The main complaint is palpitation, neck discomfort, and feeling of oppression, which is caused by an increase in the amount of ejection caused by reflux. As the heart enlarges, if the patient wants to be in the left lateral position at night, there may be a left chest pressure. When the left heart is insufficiency, you can see the shortness of breath after the activity. The late patients feel anxious even when they are quiet. In addition, there are dizziness and varying degrees of angina. It can also be seen that the patient's head oscillates forward as the heart beats.
Diagnosis
Differential diagnosis
Differential diagnosis:
Tricuspid regurgitation: severer may have fatigue, poor appetite, liver pain, abdominal swelling and lower extremity edema, jugular vein engorgement with pulsation, hepatomegaly and sputum and pulsation; and sternal left margin 4 The systolic squeaky sound of the ribs during the full systole, the murmur is enhanced at the end of deep inhalation (Carvallo sign).
