In healthy people, one cycle (beat) consists of three short stages:

Again, this is a very brief description. If you want to understand exactly how the heart works, you'd better watch this video.



Features of the artificial heart
It is important to note that an artificial heart from any manufacturer cannot replace a real one. It only gives time to wait for a donor organ. In addition to the limited service life of 180 days, an artificial heart has another disadvantage - a person is forced to carry a 4-kilogram box with liquid for its proper operation. Also, the external module contains greece number data two rechargeable batteries, which are enough for 4 hours of autonomous operation. Previously, surgeons installed SynCardia artificial hearts with four mechanical valves in patients. The main innovation of the new product from Carmat is that it uses biological valves. Thanks to natural materials, the patient's risk of blood clots is reduced, and the device works much quieter than analogues.



The operation to install an artificial heart takes place in several stages. First, a heart prosthesis is inserted into the patient's chest, which is connected to an external module via a cable. The prosthesis consists of the above-mentioned chambers and four biological valves, thanks to which it works like a real heart. The organ is also connected to the main artery of the body, the aorta and the pulmonary artery. Pumps are used to move blood, which, depending on the needs of the person, can pump blood with different forces. And to determine the needs, sensors are used that are attached to the patient's body.



Ultimately, it turns out that while waiting for a donor organ, patients partially turn into cyborgs. In 2020, the Carmat company was given permission to sell its artificial heart. Recently, an operation to install it was performed on a 39-year-old resident of the American state of North Carolina. He was diagnosed with heart failure, which is why he underwent bypass surgery — creating a new blood flow path bypassing the affected area of ​​the artery. But this method did not help, so an artificial heart was installed in his body. It is known that at the moment the man is in stable condition.
