A new artificial intelligence technology that will help cardiologists to fit stents faster and with more precision will be used to treat heart attack patients across the country. Patients at the Royal Free hospital in London are the first in the country to be treated with the AI-driven keyhole procedure before it is introduced at 20 other sites. The pioneering technology will help cardiologists to make quicker and more accurate decisions while fitting a stent, a small tube of stainless steel mesh, for coronary artery disease, a procedure known as an angioplasty. It is one of many innovative technologies being used across the NHS to help get routine services back on track after the pandemic.
