Mitral valve stenosis is a very common type of rheumatic heart valve disease, and its incidence is relatively high. Although common, the harm is not small. Mitral valve stenosis may not have any obvious symptoms at the beginning of the onset, and there will be no major events, but it is not.
Symptoms of mitral stenosis
1. Exhaled pulmonary hypertension and pulmonary congestion. In the early days, it usually occurs when the cardiac output is increased during exercise, fever, and pregnancy. With the course of the disease, slight movements, even breathing difficulties at rest. In paroxysmal atrial fibrillation, increased ventricular rate can also induce dyspnea.
Bronchial small blood vessel rupture caused by long-term pulmonary venous hypertension.
3.Cough and hoarseness
The extreme enlargement of the left atrium is caused by compression of the left main bronchus or recurrent laryngeal nerve.
4. Corresponding clinical symptoms of systemic embolism, heart failure and atrial fibrillation.
Signs of mitral stenosis
1. The first heart sound of the apical region of the heart is enhanced
Diastolic rumbling-like murmurs and open flapping sounds (open valve sounds) are typical signs of mitral valve stenosis. The interval between the second heart sound and the open valve sound indicates the degree of mitral stenosis. The shorter the interval, the heavier the stenosis. The presence of first heart sounds and the presence of flap sounds indicate that the valve elasticity is acceptable. Diastolic miscellaneous loudness is not necessarily proportional to the degree of valve stenosis. In patients with mild to moderate stenosis, the noise level is proportional to the diastolic mitral valve pressure gradient. The heavier the stenosis, the greater the pressure gradient, and the louder the noise. However, in patients with severe mitral valve stenosis, the murmur is reduced or even disappeared, showing a "dumb" mitral stenosis. The precardiac area may have mild systolic lift pulsations and the apex often touches diastolic tremors.
2. Mitral valve face and jugular vein pressure increase
Severe mitral valve stenosis can occur with mitral valve face and elevated jugular vein pressure.
