Scientists at Queen Mary University of London and Barts Health have developed an innovative tool that simulates blood flow in the aorta, helping heart surgeons plan surgeries more precisely.
Queen Mary University of LondonDec 11 2024 The digital model, known as TAVR-AID, is unique because it creates a personalized digital twin of each patient's aorta, allowing doctors to test surgical approaches before performing an operation.
Lead inventor Professor Anthony Mathur, a Queen Mary researcher and Consultant Cardiologist & Co-Director for Research at Barts Health, explains: "TAVR-AID is not designed to replace human decision-making but to enhance it. We use CT scans to build a digital twin of the patient's aorta, and echocardiography to determine the severity of the stenosis we're treating. This allows us to simulate their blood flow.
Replacing a heart valve is a delicate procedure, with the choice of valve and its replacement critical to ensuring proper blood flow and heart function. If done incorrectly, blood flow disruptions can damage the new valve. Surgeons must carefully consider factors like the size, shape, and angle of the aorta, as well as the patient's individual health needs.
