Magnesium heart stent domestic which hospital used?

Most people may not be very familiar with the details of magnesium heart stent, especially including some domestic doctors, and most people's impression of biodegradable stent is still only in the literature and some "advertisement articles", for the simple reason that the domestic hospitals do not have it! In China, regarding the technology of cardiac stenting, mainland hospitals are still stuck at the metal stenting step, which is far inferior to the technological level of Hong Kong. As early as 2012, Hong Kong began to use Abbott's fourth-generation fully-absorbable bio-vascular mold, clinical implantation of bio-fully-absorbable stents. The dissolvable stent is made of polylactic acid extracted from corn and soybean fibers, and the material can be broken down by the body two years after it is placed in the cardiovascular system, allowing the blood vessels to resume their expansion and contraction functions. The fifth generation magnesium alloy fully-absorbable scaffold (Magmaris BRS) was successfully placed in a patient in 2018, the first of its kind in the Asia-Pacific region. Here is a brief explanation of coronary heart disease treatment from an international perspective!

Coronary heart disease in the international conventional treatment method is based on metal stents, and biodegradable stents as a supplement. In foreign countries, authoritative cardiologists will give priority to recommending biodegradable stents if the patient's condition allows them to do so. After all, the effect of biodegradable stents in treating coronary heart disease is far more effective than that of metal stents, and there are no side effects, but the reason why they can't be popularized in large quantities is still as follows:

Reason 1: More than half of the people's condition is not suitable for biodegradable stents, and it is not suitable for widespread promotion

Reason 2: The surgical difficulty of biodegradable stents is much higher than that of metal stents, and not all doctors are able to do it

Simply explained, the fourth generation of biodegradable stents has differences in the characteristics of the biomaterials and metal stents, and there are many restrictions on the treatment, which are not applicable to the majority of the types of cardiovascular blockage, and the fifth generation of biodegradable magnesium stents has been upgraded in terms of materials, and the range of indications for the treatment has been enlarged, but it still cannot be applied to all vascular blockage cases. The fifth generation of biodegradable magnesium stent has been upgraded in terms of material and the scope of treatment indications has been expanded, but it is still not applicable to all cases of vascular blockage, so the biodegradable stent can not completely replace the metal stent in a short period of time, and it is by no means the so-called immature technology.

At the same time, because of the special physical properties of the material and the need for the doctor to accurately grasp the patient's condition, the overall surgical difficulty of biodegradable stents is much higher than that of metal stents, and not every doctor who can do metal stents can do biodegradable stent surgery. This is also the reason why every patient who wishes to have a biodegradable stent needs to have his/her condition evaluated in detail. The 5th generation magnesium stent has been shown to be effective in several clinical trials in cardiovascular diseases. Hong Kong hospitals have introduced the 5th generation magnesium alloy stent into clinical application and have accumulated rich clinical treatment experience, which has brought a therapeutic boon to mainland cardiovascular disease patients.
