There are four groups of people in the heart of the main valve, which is the left atrial and ventricular mitral valve between the left ventricle and aorta aortic valve, right atrium and right ventricle three tricuspid valve between the right ventricle and pulmonary artery, and the pulmonary valve. The heart is the engine of the human body, and the role of the heart valve as a one-way valve, the valve regularly open and close movement, keep the blood flow in a certain direction in the order of circulation. Heart valve disease, will seriously affect the function of the heart, and even life-threatening.

The main cause of valvular heart disease are the following: 1 rheumatic heart disease (RHD), secondary poststreptococcal autoimmune disease mainly caused by valvular thickening, even progressive fibrosis, calcification. 2 infective endocarditis, commonly associated with bacterial and fungal infections, mainly causes valvular perforation, tearing, and even destruction. 3 ischemic heart disease, more common in patients with myocardial infarction, due to papillary necrosis of the papillary muscles, or rupture, resulting in mitral regurgitation. 4 degenerative valvular disease, more common in the elderly, valve fibrosis, calcification changes in recent years, there is an increasing trend. 5 congenital malformation, congenital malformation of the valve can be varied, absent, stenosis and atresia, cleft and so on. 6 other diseases such as tumor invasion and trauma can also result in valvular disease.

Whatever the reason, the change of valve can be as follows: 1 the valve opening is limited, the orifice is narrow, the blood flow is blocked, the valve is closed in 2, the blood flow is reversed, and more than two cases coexist. Infective endocarditis and valvular dysfunction caused by myocardial infarction, sudden onset, patients can significantly increase in the short term. But rheumatic and degenerative valvular disease common, has the characteristics of chronic, progressive and occult, most of the patients in the early symptoms, only in the physical examination or consciously active palpitation shortness of breath and treatment, it was found to be suffering from the disease. In fact, these patients may have experienced several years, and even more than ten years of valvular heart disease process.

Valvular heart disease led to medical treatment of cardiac insufficiency mainly including cardiac, diuretic, vasodilator drugs and etiological treatment, to improve the heart function and slow down the progression of the disease. If the valvular disease is a simple fibrous stenosis, percutaneous balloon dilatation can also be performed. Surgical treatment may be performed for valve repair or valve replacement surgery.

Patients with valvular heart disease underwent surgery if the delay time will gradually lead to aggravation of valvular heart disease, heart lung and other vital vicera function damage, serious person can produce obstinate heart failure, cardiac cirrhosis and systemic cachexia, lose the opportunity of operation. Patients with severe valvular heart disease, often accompanied by atrial fibrillation and left atrial thrombosis, patients with cerebral embolism or other organ embolism risk. So, there has been a significant valvular disease in patients with obvious clinical symptoms, surgical treatment as soon as possible, so as not to delay the timing of treatment, causing serious consequences.
