Rheumatic valvular disease is a heart disease caused by valvular heart disease. The original smooth, thin, soft and elastic valve after repeated inflammation, valvular thickening, adhesion, deformation and shortening of chordae thicker, causing valvular stenosis or insufficiency. The disease in young people see more, more women than men, mostly 2/3 patient questioning diseases typical of rheumatism.
(1) etiology and pathogenesis
Patients with rheumatic disease. At present, it is considered that rheumatic disease is a chronic and relapsing allergic disease. Lesions involving the heart called rheumatic heart valve, often left permanent damage, and with rheumatism recurrent and progressive, produce hemodynamic change, cause heart failure, endanger life and health.
(two) patient performance
Because of the degree and location of valve damage, the patient is not the same, the most common damage is the mitral valve, followed by the aortic valve, as follows:
Mitral stenosis, left atrial left ventricular blood flow is not smooth, increased left inside the main house, increased blood pressure, left atrial hypertrophy and dilatation of pulmonary vein and pulmonary capillary pressure also increased at any time, produce dilatation and congestion, chronic lung congestion, physical activity, patient breathing difficulties, serious when were orthopnea or paroxysmal nocturnal dyspnea, cough, often accompanied by hemoptysis (pulmonary edema, cyanosis and cough a lot of pink foam sputum), this has become the left atrial failure. The condition of sustainable development leads to pulmonary hypertension, right ventricular hypertrophy due to the burden and expand, finally leads to right heart failure, caused by venous congestion, swollen liver pain, subcutaneous edema and ascites.
Cardiac auscultation could be heard and diastolic murmur. X-ray examination of left atrium and right ventricle. Abnormal left atrium and right ventricular hypertrophy were detected by ecg.
When the mitral valve is closed, the volume of left atrial blood is increased with the increase of blood flow. Into the left ventricle during ventricular diastolic left atrial excessive blood volume increased, left ventricular dilatation and hypertrophy caused by, and then gradually lose the compensatory function, pulmonary congestion, pulmonary artery pressure, right ventricular hypertrophy expansion. If the cardiac function of patients with good compensation can be no symptoms. If you lose the ability to compensate, the patient may have fatigue, palpitation, dyspnea after exertion and other left heart failure performance. At the same time, the right heart failure may occur.
Cardiac auscultation can be obviously a systolic murmur. X-ray examination of left atrium and left ventricle. Abnormal ECG findings.
Aortic valve insufficiency
Aortic valve regurgitation caused by increased left ventricular volume, compensatory expansion and hypertrophy. The disease is light or compensatory strong can be long time without symptom. The lesion was heart palpitations, shortness of breath, chest discomfort and head pulsation, few people have angina, there may be severe left heart failure symptoms.
Measurement of blood pressure in patients seen elevated systolic blood pressure, diastolic blood pressure decreased, lips and nails visible capillary pulsation (light pressure nail, the nail bed under the beating more obvious). X-ray examination is seen at the lower left heart enlargement, was also known as the aortic type heart shoe. Normal or abnormal ecg.
Aortic valve stenosis, due to left ventricular obstruction caused by compensatory hypertrophy and expansion, severe stenosis can cause coronary artery blood flow reduction and cerebral insufficiency. The light can be no obvious symptoms, severe cases due to cerebral ischemia and dizziness or fainting, or because of coronary insufficiency, cardiac hypertrophy caused by angina, even sudden death. Symptoms of left heart failure.
Auscultation of the heart aortic valve area with systolic murmur. X-ray examination can have left ventricular hypertrophy and enlargement. Abnormal change of ecg.
Combined valvular disease
One patient had at least two or more than two patients with valvular disease. The patient's performance is the comprehensive manifestation of each valve lesion.
