In-Vivo Frame Dynamicity of Self-Expanding Transcatheter Aortic Valves.
BACKGROUND Due to nitinol stent properties, self-expanding transcatheter heart valves (THVs) have the potential to adapt their frames to native annular dimension excursions during the cardiac cycle and therefore to maintain the physiological relevance of this behaviour. AIMS To assess the in-vivo variations of THV fr...
