Abstract: human heart valve lesions appear, drug therapy, surgery must, in addition to valve replacement, valve repair (terminology: valvuloplasty) in order to improve the quality of life of patients with valvular heart disease in laying a new road to recovery.
According to statistics, China's adult heart valve disease has reached about 3000000 people. And because of valvular disease may require the implementation of artificial heart valve replacement surgery patients, about 400 thousand cases, most of these patients are young adults, such as surgery can not be replaced in time, the consequences are unimaginable. So, how to get rid of heart valve disease patients "failure" phenomenon?
The human heart valve lesions appear, drug therapy, surgery must, in addition to valve replacement, valve repair (terminology: valvuloplasty) in order to improve the quality of life of patients with valvular heart disease in laying a new road to recovery.
Heart hospital experts say, the heart is a pay attention to "work flow" of the organ, it has four chambers, two small in the top, called the atrium, the other two big in the bottom, called the ventricle. Each ventricle has a one-way inflow valve and a one-way outflow valve. The three cusp of the heart opens from the right atrium to the right ventricle and the pulmonary valve opens from the right ventricle to the pulmonary artery. From the left atrium into the left ventricle is the mitral valve, while the aortic valve is open from the left ventricle to the aorta. Outflow and inflow did not go dowse Cha, with thanks to these valves in the open and close between the tacit understanding, the most important human heart assist to complete the two cycle of systemic and pulmonary circulation.
Heart disease hospital experts say, if the valve failure, valvular insufficiency (regurgitation) or open the valve (valve stenosis) can lead to dysfunction, mean valvular disease occurs, affecting the normal order of blood flow. Mitral regurgitation is a common disease of valvular disease, the etiology of most of them is the degenerative changes of the valve, that is, due to the rapid aging of the valve tissue caused by rupture of the tendon cable or too long to cause the closure of the valve leaf is not complete. Another common cause of mitral regurgitation is myocardial infarction, which is due to an injury to the mitral valve. Rheumatic fever was also the main cause of mitral regurgitation, but in the city with better medical conditions, rheumatic fever is rare. There are other causes for valvular inflammation, caused by Staphylococcus aureus, streptococcus infection or congenital valvular regurgitation lesions.
Most of mitral regurgitation in preoperative patients have symptoms of shortness of breath, palpitation, more than half of the cardiac function in patients with grade III or IV, severe cough, edema of lower extremity and gas activities. The diagnosis is relatively easy, auscultation in apical systolic murmur features, echocardiography can clearly show the lesions of the ear of the valve, and can evaluate the severity of the disease.
In the past, there was only one way to solve the problem of heart valve disease, that is, valve replacement, mechanical or biological valve to replace the original work can not continue to work. The disadvantage is the need for monitoring the coagulation index changes and the use of anticoagulants. Although the "nature of love" is the human heart, but the "spare parts" or by the parents, now, with the development of medical technology, mitral valve plasty was born and matured, the operation is very common in Europe and the United states.
Compared with valve replacement, valve repair operation more obvious advantages, because the first is still own the valvular tissue, only 3 months of anticoagulant therapy after the operation, you can disable all the drugs, does not require life-long anticoagulation, avoid after cardiac valve replacement surgery for cerebral infarction or cerebral hemorrhage complications such as insufficient anticoagulation or overdose. Moreover, no long-term blood anticoagulant monitoring indicators, to avoid the busy and often visit the long-term medication of trouble, make the quality of life of patients improved significantly after surgery. Because of its reliability and repeatability, the operation has been paid more and more attention in our country, and the requirement of the technique and quality of cardiac surgery is very high. The range of indications for valve repair surgery is the same, not all valvular lesions can be formed, and the best surgical approach is the best choice for the type of valvular disease.
