Which hospital in China used magnesium metal heart stent?

Perhaps most people don't know much about the details of magnesium alloy heart stent, especially some doctors in China. Perhaps most people's impression of biodegradable stents is only in literature and some "advertising articles", for the simple reason that there are no domestic hospitals! In China, hospitals in the Mainland are still stuck in the technology of metal stents, which is far from the technical level of Hong Kong. As early as 20 12 in Hong Kong, Abbott's fourth-generation fully absorbable biological vascular stent was used for clinical implantation of fully absorbable biological stent. Soluble scaffolds are made of polylactic acid extracted from corn and soybean fibers. The substance can be decomposed by the human body after being put into the cardiovascular system for two years, so that the blood vessels can resume the functions of dilation and contraction. 20 18 fifth generation magnesium alloy total absorption stent (Magmaris BRS) was successfully implanted in patients, which was the first case in Asia-Pacific region. Let's briefly explain the treatment of coronary heart disease from an international perspective!

The conventional treatment of coronary heart disease in the world is mainly metal stent, supplemented by degradable stent. In foreign countries, when the patient's condition can be treated as a degradable stent, authoritative cardiologists will give priority to it. After all, the effect of degradable stent itself in treating coronary heart disease far exceeds that of metal stent without side effects. There are two reasons why it cannot be widely promoted:

The first reason: more than half of people are not suitable for biodegradable stents and are not suitable for large-scale promotion.

The second reason: biodegradable stents are much more difficult to operate than metal stents, and not all doctors can do it.

Simply explain, the biomaterial characteristics of the fourth generation biodegradable stent are different from those of metal stents, and there are many treatment restrictions, so most types of cardiovascular blockages are not applicable. The fifth-generation biodegradable magnesium stent has been upgraded in materials, and the range of indications for treatment has been expanded, but it is still not suitable for all cases of blood vessel blockage, so it is impossible for biodegradable magnesium stent to completely replace metal stent in a short time, which is by no means the so-called immature technology.

At the same time, due to the special physical characteristics of the material and the need for doctors to accurately grasp the patient's condition, the overall operation difficulty has been improved a lot in the treatment of metal stents. Not every doctor who can do metal stents can do degradable stent surgery. This is why every patient who wants to do biodegradable stent needs to evaluate his condition in detail. The fifth generation magnesium alloy stent has achieved good results in many clinical trials of cardiovascular diseases. The fifth generation magnesium alloy stent has been introduced into clinical application in hospitals in Hong Kong, and accumulated rich clinical treatment experience, which has brought therapeutic gospel to patients with cardiovascular diseases in mainland China.
