Overview
A new study explores using an AI-powered monitoring tool to reduce the risk of stroke during transcatheter aortic valve replacement (TAVR) procedures. TAVR is a method used to replace a narrowed aortic valve that fails to open properly. Strokes are a significant risk during these procedures, so finding ways to minimize this risk is crucial.Study Details
From October 2021 to May 2022, 31 patients undergoing TAVR were included in this study. Researchers used a robotic system with AI to monitor the patients’ brain activity in real-time during the procedure. This system adjusts itself automatically and helps detect tiny clots, known as high-intensity transient signals (HITS), which can lead to strokes.Key Findings
- Patient Demographics: The average age of the patients was about 80 years, and just over half were men.
- Cerebral Protection: In 16 cases, a cerebral protection device was used to filter out clots.
-
Results:
- Patients with the protection device had significantly fewer clots compared to those without it.
- The most critical time for detecting clots was during the positioning and implantation of the valve.
- One patient without the protection device experienced a minor stroke after the procedure.
