Rheumatic heart disease is gradually aggravated, the patient has just had rheumatic heart disease for a short period of time, there is a simple mitral stenosis, and the valve quality is relatively good, belong to the junction of adhesions, there used to be a method called closed dilatation, but now it has been gradually replaced by balloon dilatation, can be used through interventional methods, using the balloon to dilate the stenosis, adhesions part, after the dilatation open to make the stenosis release. As the disease progresses, the adhesions become more severe, causing sclerosis or even calcification, and surgical intervention is required. Surgical intervention can be done in the following two ways: 1) valvuloplasty. Nowadays, the technology of valvuloplasty is getting better and better, and many patients with mitral stenosis can have their stenosis lifted through valvuloplasty and retain their own valves; 2) valvular replacement can be performed if the effect of valvuloplasty is not good, and valvular replacement is to cut out the diseased valve and replace it with an artificial biological valve or mechanical valve.
