What is the cause of combined valvular disease? Combined valvular disease is mostly caused by rheumatic heart disease, also has bacterial endocarditis, degenerative changes, trauma and other causes of valvular disease. There are several forms of combined valvular disease:

1, the same disease involving two or more than two valves, the most common cause of rheumatic mitral and aortic valve or other valve disease; followed by infective endocarditis and invasion of mitral and aortic or tricuspid valve, pulmonary valve three.

2, the lesions originated from a valve, with the development of the disease can affect or involve another valve, resulting in relative stenosis or insufficiency. Such as rheumatic mitral stenosis can cause pulmonary hypertension, pulmonary hypertension to right ventricular pressure overload induced right ventricular hypertrophy, dilatation and three tricuspid insufficiency.

3, or more than two kinds of pathogenic factors involved in different types of valves, such as moist mitral valve disease complicated with infectious aortic valve inflammation.

Mitral stenosis is the most common type of mitral valve stenosis associated with severe mitral regurgitation in 10% patients with valvular disease. When mitral stenosis and aortic valve stenosis, mitral stenosis can mask the clinical manifestations of aortic stenosis. But the clinical manifestation of mitral stenosis caused by, such as lung congestion, hemoptysis, atrial fibrillation and systemic embolism incidence than simple aortic stenosis. Mitral regurgitation associated with aortic regurgitation is a relatively common combination, which is often characterized by aortic regurgitation. Mitral valve regurgitation and aortic stenosis at the same time there is a dangerous situation, on the one hand can make the left atrial decompensation and pulmonary congestion occur earlier, on the other hand can produce organ insufficiency symptoms.
