Randomized Controlled Trial Multicenter Study Comparative StudyBioprosthetic Valve Performance After Transcatheter Aortic Valve Replacement With Self-Expanding Versus Balloon-Expandable Valves in Large Versus Small Aortic Valve Annuli: Insights From the CHOICE Trial and the CHOICE-Extend Registry.
The aim of this study was to compare self-expanding and balloon-expandable transcatheter heart valves (THVs) in large versus small aortic valve annuli. ⋯ Older-generation balloon-expandable THVs were associated with less PVR than self-expanding THVs in patients with large but not small annuli. The next-generation self-expanding THV has improved sealing in patients with large annuli and may have potential advantages in patients with small annuli.
