Objective: Data remain limited on factors influencing the selection of redo-transcatheter aortic valve replacement (TAVR) versus surgical explant in patients with failing transcatheter heart valves. This study aimed to identify clinical and procedural factors guiding treatment decisions.
Methods: This single-center, retrospective study included all patients who underwent aortic valve reintervention following prior TAVR at a U.

Background: Understanding trends in transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) utilization is essential for predicting valve-in-valve (ViV) TAVR usage, a viable option for failed bioprosthetic valves that presents a promising avenue for lifetime management of aortic stenosis.
Objectives: This study aimed to predict and compare the future annual ViV volume in the United States and Japan based on past and current TAVR/SAVR utilization under some underlying assumptions.
Methods: We developed a MATLAB-based Monte Carlo model engine to simulate the lifespan of bioprosthetic TAVR and SAVR valves.

Division of Cardiothoracic Surgery, Washington University in St. Louis, St. Louis, Missouri, USA.
Background: Aortic valve-in-valve (AViV) replacement for is approved for patients with degenerated surgical valves at high or prohibitive surgical risk, mostly on the basis of small series with short-term follow-up.
Objectives: The aim of this study was to analyze the outcomes of AViV therapy using contemporary balloon-expandable valves (BEVs) in a large series with mid-term outcomes.
Methods: BEV AViV patients (June 2015 to December 2023) in the Society for Thoracic Surgeons (STS)/American College of Cardiology TVT (Transcatheter Valve Therapy) Registry were propensity matched to native transcatheter aortic valve replacement (TAVR) patients.

We report an interesting complex percutaneous coronary intervention (PCI) case in an 84-year-old male, with typical angina pectoris after previous coronary artery bypass graft (CABG) surgery and coronary double chimney stenting during a transcatheter aortic valve replacement (TAVR)-in-TAVR procedure with double self-expanding transcatheter heart valve (THV) in his degenerated stentless aortic surgical valve bioprosthesis.
