When it comes to Bolivia, people will think of the dreamy "Urban of the Sky" Uyuni. However, in this very romantic country, there is a hidden invisible killer - congenital heart disease. ("The Mirror of the Sky" Uyuni) The terrain of Bolivia is dominated by plateaus with an average elevation of over 3,000 meters. Its administrative capital, La Paz, is more than 4,000 meters above sea level and is the highest capital in the world. (Bolivia's capital: La Paz) Bolivia's air oxygen content is only 70% of the plain area. Insufficient oxygen may cause a series of physiological and pathological changes including cardiac function. Congenital heart disease is one of the most common types. In Bolivia, the number of children with congenital heart disease is 10 times the world average. Infants diagnosed with congenital heart disease are prone to die, and even if they survive, they tend to lose weight and exercise. At the same time, the high cost of surgery and the long recovery time have become the life of the Bolivians. Fortunately and miraculously, some people skillfully use the ancient weaving techniques of the local Aymara people to make a miracle of life happen. Freudenthal is a child cardiologist. He was born into a medical family and opened a clinic in La Paz to save congenital heart disease patients. However, traditional thoracotomy surgery can cause great trauma to patients. Since 1998, he has begun to develop a small occluder to reduce the suffering of patients. However, the structure of such an occluder is too delicate to be completed by the machine. So, Freudenthal thought of the Aymara people who were good at weaving.
