On the 16th, the reporter learned from the Fuwai Cardiovascular Hospital of the Chinese Academy of Medical Sciences that the team led by the president of the hospital, the Chinese Academy of Engineering Hu Shengshou and the director of the surgical management committee Wang Hao adopted the valve implantation system independently developed by China. The elderly patients with high-risk heart disease successfully performed the "Tactical Minimally Invasive Aortic Valve Implantation (TAVI)", and did not open the chest, the heart does not stop. This world-leading technology has enabled patients who have been unable to treat them in the past to be thoroughly treated and regained their vitality.
"Aortic stenosis or regurgitation is a common heart disease in middle-aged and elderly people. Severe aortic valve disease will eventually lead to heart failure." Hu Shengshou pointed out that in general, the average survival time of patients after symptoms is only two or three years, and at any time. Faced with the risk of sudden death. However, conventional surgical replacement valves require the sternum to be sawed from the center and require extracorporeal circulation support, which is not only traumatic, hemorrhagic, but also has a high risk of multiple organ failure. Therefore, at least 30% to 50% of high-risk patients in China will give up treatment, which has become a major problem in the academic field of cardiac surgery.

Wang Wei introduced that the "periosteal minimally invasive aortic valve implantation" performed for two patients only cut a small opening of 3 to 5 cm in the left front chest, and then opened a small hole from the apex, and then manipulated a small hole. The slender delivery sheath implants a new bioprosthetic valve that takes only one hour to complete the operation and does not exceed 100 ml. After the operation, the patient quickly wakes up and leaves the ventilator. After 2 to 5 days, he can walk down the ground. More importantly, the operation adopted the self-developed "Cerve Aortic Valve Implantation System (J·ValveTM)", which overcomes the worldwide problem that the operation can not be applied to aortic valve insufficiency.
Wang Wei explained that minimally invasive aortic valve implantation is divided into transarterial retrograde approach and transapical approach. In layman's terms, the former is to send the valve from the patient's artery to the heart, while the latter enters directly from the apex. However, due to the limitations of arterial conditions, many patients with peripheral arteries, severe arteriosclerosis, or aortic "porcelain" are inoperable. From the apex approach, not only the surgery "path" is closer, but also can reduce vascular complications, avoid aortic plaque detachment, especially solve the problem that large-sized valves can not pass the smaller diameter of the artery, this is for Asians. Especially critical (Asian blood vessels are generally thinner than Westerners). Not only that, before the trial, all international minimally invasive aortic valve implantation can only treat aortic stenosis, can not treat simple aortic regurgitation, and China's self-developed system can provide new treatments for doctors around the world. It is a major breakthrough in the field of international cardiovascular disease.
The paper and plastic packaging bags are usually composed of two sides, one is the paper that passes through and discharges the sterilization factor, the other is the tonguing composite film (plastic film) that cannot permeate the liquid, air and gas, and the tonguing composite film consists of at least two layers (polypropylene inner layer and polyester outer layer). The exchange of air disinfection factors is carried out on one side of the paper. Due to the data, it also has the outstanding function of microbial barrier, and makes the package visible to the goods in the package, High quality craft Paper Bag with window is made of food-grade material 100% , and you can pack the food safely.
