Stent Frame Decoupling Following Self-expandable TAVR
Anno:
2024
Introduction Transcatheter heart valve (THV) deformation may affect leaflet kinematics and coaptation, with potential formation of hypoattenuated leaflet thickening (HALT). The flexible nitinol frame of the self-expandable THV, conforms to the native annulus shape while maintaining the prosthesis in a higher position. This arrangement is called stent-frame ‘decoupling’ and…
Leaflets and extra-leaflets hypoattenuated lesions following TAVR
Anno:
2024
Introduction Subclinical leaflets thrombosis is a condition diagnosed with multi-detector computer tomography (MDCT) characterized by a meniscal-shaped hypoattenuated lesion of one or more leaflets. Transcatheter aortic self-expandable valves are commonly manufactured with pliable pericardium over a nitinol frame that forms the leaflets and the extra-leaflets components, such as the…
