Bicuspid valve CT registry of balloon-expandable TAVR: BETTER TAVR registry.

Background: The anatomic substrate of bicuspid valves may lead to suboptimal TAVR stent expansion and geometry.

Aim: We evaluated determinants of stent geometry in bicuspid valves treated with Sapien transcatheter aortic valve replacement (TAVR) valves.

Methods: A multicenter retrospective registry of patients (February 2019 to August 2022) who underwent post-TAVR computed tomography to determine stent area (vs.

Impact of Frailty and Prefrailty on Outcomes of Transcatheter or Surgical Aortic Valve Replacement.

Background: Randomized trials have shown short- and mid-term benefits with transcatheter versus surgical aortic valve replacement (TAVR versus SAVR) for patients at intermediate or low-risk for surgery. Frailty and prefrailty could explain some of this benefit due to an impaired ability to recover fully from a major surgical procedure.

Methods: We examined 2-year outcomes (survival and Kansas City Cardiomyopathy Questionnaire [KCCQ] scores) among patients at intermediate or low surgical risk treated with transfemoral-TAVR or SAVR within the PARTNER (Placement of Aortic Transcatheter Valves) 2A trial, SAPIEN 3 intermediate-risk registry, and PARTNER 3 trial.
