Scientists from Boston have developed a prosthetic heart valve that grows with a child
The heart valve, which does not require replacement with age, was created by scientists from the Boston Children's Hospital. The prosthesis does not expand independently, but with the help of a balloon catheter, the installation of which is considered to be “minimally invasive”.
A flexible implant stretches and grows with the baby's body. Laboratory tests of the development, which were carried out on animals, showed that the prosthesis of the heart valve retains its functionality even when stretched. It can also work at various pressures. Description of the study published in the journal Science Translational Medicine.
According to the American Heart Association, nine out of 1,000 babies are born with congenital heart defects. This makes the disease the most common birth defect. It is manifested by violations in the walls of the heart, arteries or valves close to it.
Today, valve implants change every few years, which is associated with the growth and development of the child. For example, if the prosthesis was installed for the first time at the age of 2, then up to the age of 18 it will take about five operations to replace it.
A recent study by American scientists showed that living together with an optimistic partner can prolong life and save many diseases. In particular, the risk of developing Alzheimer's disease, dementia and other cognitive impairment is reduced.
