Purpose Of Review: As TAVR is increasingly performed on younger patients with a longer life expectancy, the number of redo-TAVR procedures is likely to increase in the coming years. Limited data is currently available on this sometimes challenging procedure. We provide a summary of currently published literature on management of patients with a failed transcatheter aortic valve.
Recent Findings: Recent registry data have increased the clinical knowledge on redo-TAVR. Additionally, numerous bench studies have provided valuable insights into the technical aspects of redo-TAVR with various combinations of valve types. Redo-TAVR can be performed safely in selected cases with a high procedural success and good short-term outcomes. However, at present, the procedure remains relatively infrequent and many patients are not eligible. Bench testing can be useful to understand important concepts such as valve expansion, neoskirt, leaflet overhang, and leaflet deflection as well as their potential clinical implications.

Background: Aortic stenosis (AS) is a complex condition with various hemodynamic subtypes, each with distinct clinical profiles and outcomes. This study aimed to assess the characteristics and outcomes of different AS phenotypes based on flow and gradient patterns.
Methods: In this retrospective cohort study, we included 930 patients who underwent transcatheter aortic valve replacement (TAVR) for severe symptomatic AS at Mayo Clinic sites from 2012-2017.

Background: Limited data exist on the impact of polyvascular disease (PolyVD) on clinical outcomes in female patients undergoing transcatheter aortic valve replacement (TAVR). We therefore sought to investigate clinical outcomes in women with versus without PolyVD undergoing TAVR.
Methods: Female participants from the multicentre Women's International Transcatheter Aortic Valve Implantation (WIN-TAVI) registry were categorized based on the presence or absence of PolyVD.

Prosthetic valve endocarditis (PVE) is the medical term used to describe a focus of infection involving a valvular substitute within the heart. It is a significant concern in the field of cardiology, and the epidemiology of PVE has seen notable developments over the last five decades. The disease currently affects an older demographic and is becoming increasingly prevalent in patients with transcatheter-implanted valves.

Approximately 50% of individuals eligible for transcatheter aortic valve implantation (TAVI) have coronary artery disease (CAD). The influence of CAD, both its prevalence and severity, on post-TAVI clinical results has yielded conflicting findings. Recent research has shown positive results for the use of computed tomography angiography and functional percutaneous evaluation of coronary lesions in the pre-TAVI assessment, besides the classic coronary angiography.

Background: The aim of this study was to assess the possibility of image improvement of ECG-gated, high-pitch computed tomography angiography (CTA) of the thoracoabdominal aorta before transaortic valve replacement (TAVR) on a novel dual-source photon-counting detector CT (PCD-CT) in the setting of suboptimal low-contrast attenuation.
Methods: Continuously examined patients who underwent an ECG-gated, high-pitch CTA of the aorta on a PCD-CT with a contrast decrease of at least 50% between the ascending aorta and the common femoral arteries (CFA) were included. Patient characteristics were documented.
