Why does atrial fibrillation occur in the highest percentage of cases of wind heart disease? Studies have shown that atrial fibrillation occurs in up to 30% of cases of wind heart disease, a rate that is several or even tens of times higher than that of other diseases. Why is the incidence of atrial fibrillation so high? First of all, from the perspective of the pathogenic process of wind heart disease, wind heart disease is a systemic immune response triggered by the flu, from arthritis, to heart inflammation, and finally to heart valve stenosis. This makes it easy to understand why atrial fibrillation occurs in patients with wind heart disease: 1. Heart inflammation leads to fibrosis of the endocardium, which can produce ectopic excitation sites. 2. 2, Valve stenosis can lead to increased pressure in the left atrium. When atrial fibrillation appears in wind heart disease, if the valve stenosis is severe enough to require surgical treatment, atrial fibrillation should be treated with surgical ablation at the same time; if surgical surgery is not required, catheter ablation should be chosen to treat atrial fibrillation. To date, our center has performed more than 500 catheter ablations for atrial fibrillation of wind heart disease, the largest number of cases in the world, and has published articles in prestigious international journals.
