Robotic Heart Catheterization Inside an MRI
A team of scientists received a four-year, $3.7 million NIH grant to attempt what they say would be a medical first: performing robotic heart catheterization while the patient is inside a magnetic resonance imaging (MRI) machine.
A physician controlling a micro-robotic device would perform the procedure wearing a mixed-reality headset and the goal would be to achieve unparalleled surgical precision. In this case, that would mean for a procedure known as a left atrial appendage occlusion (LAAO), which is used for managing stroke risk in atrial fibrillation (AFib) patients.
By demonstrating the benefits of using AR-guided robotic surgery for this procedure, the researchers hope to increase its availability to AFib patients — especially those whose life expectancy is greater than 20 years.
The two big pieces of the work — the robotic catheter operating inside an MRI and the high-speed MRI imaging itself — provide significant challenges. Combining them required bringing together several experts from different disciplines.
