Abstract: the methods of examination of mitral regurgitation were divided into chest X-ray examination, electrocardiogram examination and sectional echocardiography. In patients with mitral stenosis and regurgitation, the mitral valve orifice was small and not complete.
Treatment of rheumatic mitral regurgitation as the valve lesions can be used, mitral annulus or seam shrinkage reconstruction; mitral valve repair for mitral valve replacement surgery; the three surgical methods. However, in the end how should we find it? The following is an explanation of the method of auxiliary examination for rheumatic mitral regurgitation:
Chest X-ray examination
Chest X-ray examination showed that the left atrium and left atrial enlargement, right heart margin double high density shadow, a dilatation of the pulmonary artery, the aortic arch is small. Chest X-ray fluoroscopy can see left atrial systole showed expansile pulsation, left ventricular beat strongly, esophageal barium meal examination showed left atrial esophageal compression extended move to the rear, pulmonary vascular had no obvious change or mild expansion, X-ray examination can ascertain mitral annular calcification disease.
Mild mitral regurgitation may present abnormal ECG signs. Moderate regurgitation and longer duration showed left ventricular hypertrophy, accompanied by strain left axis deviation. Cases of pulmonary hypertension may show signs of left and right ventricular hypertrophy. Atrial fibrillation is common in patients with long course of disease.
Cardiac catheterization and selective left ventricular angiography: left atrial pressure, average systolic pressure is 2 ~ 2.7kPa (15 ~ 20mmhg), the pressure curve showed that V wave and a sharp, abrupt decline, V wave greater than Q wave, pure mitral regurgitation cases of left atrial and left ventricular diastolic pressure is not obvious. Pulmonary capillary wedge pressure resistance and pulmonary circulation can be increased in different degrees, cardiac output decreased, selective left ventricular systolic angiography showed contrast agent back into the left atrium, the left atrium according to the contrast agent in return flow size and developing plot, can estimate the severity of mitral valve insufficiency, back flow more contrast agent can fill the left atrium and the high concentration of contrast agent into the aorta is relatively reduced. Patients who are 40 years of age or older who are considered to be candidates for surgery should be treated with selective coronary angiography.
There were no abnormal signs of mild mitral regurgitation, and the left ventricular volume load was gradually increased after the closure of the left ventricular and left atrial enlargement. The ventricular septal and left ventricular posterior wall systolic force was enhanced by the sectional echocardiography. The thickening and thickening of the flap, tendon and papillary muscle were observed, and the echo reflex was enhanced.
In patients with mitral stenosis and regurgitation, the mitral valve orifice was small and not complete. Due to rupture of mitral chordae tendineae caused by insufficiency, echocardiography can display section of leaflet chordae tendineae during ventricular contraction turned into left atrial, ventricular diastolic and left atrial return quickly from the left ventricle. Patients with mitral annular calcification showed a calcified plaque or nodular enhancement of the intensity of the echo, severe calcification showed large or whole ring crescent echo enhancement.
