Transcatheter Tricuspid Valve Replacement Stent Geometry: Implications for Hypoattenuated Leaflet Thickening and Reduced Leaflet Motion

Key Points

• To evaluate how the geometry of transcatheter tricuspid valve replacement stents affects leaflet thickening and motion.
• Randomized trial design
• Assessment of leaflet motion and thickening parameters
• Comparison of different stent geometries
• Significant correlation between stent geometry and hypoattenuated leaflet thickening observed, p<0.01.
• Reduced leaflet motion associated with specific stent designs, leading to improved valve function, p=0.03.
