Scientists from the Texas Heart Institute, with the support of colleagues from the company BiVACOR, have transplanted a fully mechanical heart on a magnetic suspension into a human. reports Texas Heart Institute (THI).
The mechanical heart is a two-chamber rotary pump made of titanium with only one moving part. The titanium pump, called TAH (total artificial heart), stands out for its ability to accurately reproduce the functions of both ventricles of the heart by applying blood pressure thanks to a rotor that works on the magnetic principle.
The heart prosthesis is capable of providing a blood flow of 12 litres per minute, which is enough to allow a healthy adult male to lead an active lifestyle, including sports. However, scientists stressed that the mechanical organ is provided for temporary use until the patient can receive a biological heart transplant.
The researchers call the mechanical heart a “bridge to transplantation” for patients with severe heart failure (univentricular or biventricular). The scientists plan to continue the research by performing experimental transplants on four more volunteers.
