There are three criteria for critical heart valve disease: 1. oversized giant left ventricle, LVEDD>80mm, LVESD〉60mm, EF<0.50, FS<0.25, heart to chest ratio>0.70. 2. small left ventricle with simultaneous left ventricular atrophy and severe pulmonary hypertension. LVEDD<35mm, PH>60mmHg. 3. cardiac cachexia, cardiac insufficiency 3-4 grade. The liver, kidney, lung and other organs are moderately or more dysfunctional, and immune function is low. Heart valve disease combined with atrial fibrillation When germs infect the heart valves, causing heart valve malformation or deformation and mechanical blood flow disorders caused by the main lesions, known as rheumatic heart valve disease. Atrial fibrillation can be easily complicated by the development of heart valve disease to a certain extent. Atrial fibrillation occurs when the atria undergo fast and irregular impulses at a frequency of 350 times per minute, causing uncoordinated atrial fibrillation, resulting in the loss of effective atrial contraction. …… Valvuloplasty and replacement for rheumatic heart disease Heart valve disease is a very common type of heart disease, with valve disease accounting for nearly 1/3 of all heart surgery. heart valve disease Heart valve disease is traditionally treated with valvuloplasty, bioprosthetic or mechanical valve replacement. The Department of Cardiac Surgery at Shanghai Yuanda Cardiothoracic Hospital uses a small axillary incision for valvuloplasty, bioprosthetic or mechanical valve replacement. This treatment method is less invasive, aesthetic and postoperative recovery …… 1 case of heart valve replacement for high-risk wind heart disease Shanghai Yuanda Cardiothoracic Hospital successfully performed prosthetic valve replacement surgery for a patient with critical wind heart disease. The patient had a long course of wind heart disease with complex conditions, including severe mitral stenosis and severe closure insufficiency, moderate aortic stenosis and moderate to severe closure insufficiency, moderate to severe tricuspid valve closure insufficiency, pulmonary hypertension and other lesions. ……
