Each person's heart has four valves. These four thin, paper-wing valves are like the four doors of the heart—the heart's every contraction and relaxation, and the valve switches once. Once the "gate" of the heart is broken, it is necessary to "change the door." The reporter learned from the Fuwai Hospital that the valve developed by China itself is expected to be listed in the next year. At that time, the Chinese will use the “gateway†of the “Made in China†heart that is safe, effective and inexpensive.
In the past, human heart valves had problems, and the thoracotomy was performed to remove the damaged valve and implant a new artificial valve. In recent years, patients who are unable to perform conventional thoracotomy or have a high risk of surgery can be treated with interventional therapy to replace the valve through a catheter. Although the interventional valve replacement is a minimally invasive procedure, it has high technical requirements. This technology was applied to the clinic in China in 2010. At present, there are only a few large medical centers in the country that can complete this minimally invasive surgery. The main reason is minimally invasive surgery. Replacement valves have high requirements for doctors' skills and experience; in addition, the development of artificial valves and other medical devices is relatively lagging, which is one of the reasons why this technology cannot be applied on a large scale in China.
In order to enable more high-risk patients with valvular heart disease to be treated, China has included the development of artificial valves for minimally invasive treatment in the “Twelfth Five-Year Planâ€. The project was organized and implemented by the famous cardiologist Gao Runlin. The National Cardiovascular Center Fuwai Hospital as the leader unit, combined with a number of well-known large hospitals to form a strong scientific research team, and finally developed a domestic heart valve, and has been smooth Completed 80 clinical trials; this project also created a technical route from valve evaluation to interventional operation, which indicates that future interventional valve replacement is expected to be widely promoted in many hospitals across the country, rather than being limited to a few in the past. Large hospitals carry out.
It is understood that the current cost of importing a valve is about 250,000 yuan, plus surgery costs and other consumables, an operation requires about 300,000, and with the domestic valve, the patient's treatment costs are expected to be reduced by one-third. About half. In addition, during the development of the project, the research team also found that the valvular disease in China has great differences in disease characteristics and pathological morphology, which also indicates the necessity of independent research and development of domestic valves. It is reported that China's self-developed valves are expected to be listed in the next year.
