Rheumatic valvular heart disease [outlined]

Rheumatic heart valve disease called rheumatic heart disease, rheumatism is caused by chronic heart valve damage. I formed the valve stenosis or regurgitation, or stenosis and regurgitation exist at the same time, lead to hemodynamic changes Finally decompensated heart failure, the form of congestive heart failure. The disease was particularly prevalent in the 20 to 40-year-old young adult. With a reduction in the incidence of rheumatic fever, reducing new cases, the patients continued high incidence of age after the transfer. Two thirds of whom are women, about two-thirds of a history of rheumatic fever, stenosis occurred over time in the first rheumatic fever after more than two years. Clinical data showed the valve involvement rate : 95% of mitral and aortic valve 20%~35%. 5% of the tricuspid valve, pulmonary valve less than 1%. Clinical pure mitral valve disease in the most common, accounting for about 70% to 80%, mitral valve with aortic valve disease times, about 20% -30%, simple aortic valve disease accounts for about 2% -5%. Valvular lesions occurred after regurgitation and stenosis more exist at the same time, one of the more notable.
