The cost of interventional treatment for ventricular septal defect is basically around 30,000 yuan, which is mainly divided into the cost of surgery and materials, mainly the cost of materials. In the process of blocking, a device for puncturing, a device for catheter, or a delivery device, will be used. The cost of the procedure tends not to be expensive, so the overall cost adds up to about 30,000 yuan. This procedure is very mature, and once the interventional block is done, the patient is basically the same as a normal person. Of course, this is only if there are no significant heart complications and the heart chambers are structurally normal. If the heart cavity structure is already abnormal and there is pulmonary hypertension, the patient may still have symptoms even after the procedure, but of course this procedure should be done to slow down the progression of the heart disease.
