Femoral or Radial Secondary Access in TAVR: A Subanalysis From the Multicenter PULSE Registry.

Background: Transradial secondary access (TR-SA) may serve as an alternative to the traditional femoral secondary access (TF-SA) for pigtail placement in transcatheter aortic valve replacement (TAVR).

Objectives: The aim of this study was to assess the incidence of secondary access-related vascular complications after TR-SA or TF-SA in TAVR.

Methods: The PULSE (Plug or sUture based vascuLar cloSurE after TAVR) registry retrospectively evaluated data of 10,120 patients who underwent transfemoral TAVR at 10 heart centers from 2016 to 2021.

Impact of Measured and Predicted Prosthesis-Patient Mismatch After Transcatheter Aortic Valve Replacement.

Background: Prosthesis-patient mismatch after transcatheter aortic valve replacement (TAVR) can be measured echocardiographically (measured prosthesis-patient mismatch [PPMm]) or predicted (predicted prosthesis-patient mismatch [PPMp]) using published effective orifice area (EOA) reference values. However, the clinical implications of PPM post-TAVR remain unclear.

Objectives: This study aimed to elucidate the prevalence of PPMm and PPMp post-TAVR and their impact on mortality in a large international cohort.

TAVI with the ACURATE neo2 in severe bicuspid aortic valve stenosis: the Neo2 BAV Registry.

Background: The ACURATE neo2 is a contemporary transcatheter aortic valve implantation (TAVI) system approved for the treatment of severe aortic stenosis in Europe. The ACURATE neo2 has not been evaluated in bicuspid aortic valve (BAV) stenosis.

Aims: We sought to evaluate the safety and efficacy of ACURATE neo2 in patients with BAV stenosis.

1-Year Outcomes of Transcatheter Aortic Valve Replacement Using a Self-Expanding vs Balloon-Expandable Transcatheter Aortic Valve.

Background: Mid-term comparative data for the self-expanding ACURATE neo2 transcatheter heart valve and the balloon-expandable SAPIEN 3 Ultra are lacking.

Objectives: The aim of this study was to compare 1-year outcomes after transcatheter aortic valve replacement of these 2 valves.

Methods: A total of 2,106 patients from 3 centers (neo2, n = 1,166; Ultra, n = 940) undergoing transfemoral transcatheter aortic valve replacement were analyzed retrospectively.

Aortic valve calcification volume and prognosis in patients undergoing transcatheter aortic valve implantation.

Introduction And Objectives: It is unknown whether aortic valve calcium volume, as measured by contrast-enhanced computed tomography angiography (angio-CT), is associated with mortality in patients undergoing transcatheter aortic valve implantation (TAVI). We aimed to confirm that contrast-enhanced aortic valve calcium correlates with noncontrast-enhanced calcium score and provides useful prognostic information in patients undergoing TAVI.

Methods: This retrospective observational study included patients from 2 high-volume TAVI centers in Germany, all of whom underwent high-quality angio-CT prior to TAVI.

Effects of high- versus low-intensity lipid-lowering treatment in patients undergoing serial coronary computed tomography angiography: results of the multi-center LOCATE study.

Aim: To evaluate the effects of lipid-lowering medications of different intensities on total, calcified, and non-calcified plaque volumes in patients undergoing serial cardiac computed tomography angiography (CCTA).

Methods: Individuals with chronic coronary syndromes from 11 centers were included in a retrospective registry. Total, calcified, and non-calcified plaque volumes were quantified and the relative difference in plaque volumes between baseline and follow-up CCTA was calculated.

Commissural alignment and the ACURATE neo2 transcatheter aortic valve: Impact on valve performance.

Background: Transcatheter aortic valve replacement (TAVR) is increasingly being used to treat severe aortic stenosis in younger patients. Accordingly, lifetime management regarding future reintervention and coronary access is a concern.

Aims: To assess the impact of commissural alignment on ACURATE neo2 transcatheter aortic valve (TAV) performance.

[Catheter-based and surgical treatment for aortic valve diseases].

The pathophysiology of aortic valve diseases is of predominantly degenerative nature, characterized by calcific aortic valve stenosis, which is associated with a reduction in prognosis. The prevalence of aortic valve insufficiency also increases with advancing age. Timely causal treatment is crucial in the management of aortic valve diseases.

ACURATE neo2 Versus SAPIEN 3 Ultra Transcatheter Heart Valve in Severe Aortic Valve Calcification: A Propensity-Matched Analysis.

Background: Comparative data on transcatheter self-expanding ACURATE neo2 (NEO2) and balloon-expandable SAPIEN 3 Ultra prostheses in technically challenging anatomy of severe aortic valve calcified aortic annuli are scarce.

Methods: A total of 1987 patients with severe native aortic stenosis treated with the self-expanding NEO2 (n=1457) or balloon-expandable SAPIEN 3 Ultra (n=530) from January 2017 to April 2023 were evaluated. The primary end point was procedural outcome according to the Valve Academic Research Consortium 3 definitions.

Comparison of Two Contemporary Quantitative Atherosclerotic Plaque Assessment Tools for Coronary Computed Tomography Angiography: Single-Center Analysis and Multi-Center Patient Cohort Validation.

Background: Coronary computed tomography angiography (CCTA) provides non-invasive quantitative assessments of plaque burden and composition. The quantitative assessment of plaque components requires the use of analysis software that provides reproducible semi-automated plaque detection and analysis. However, commercially available plaque analysis software can vary widely in the degree of automation, resulting in differences in terms of reproducibility and time spent.

Cardiac decompensation of patients before transcatheter aortic valve implantation-clinical presentation, responsiveness to associated medication, and prognosis.

Aims: Cardiac decompensation (CD) in patients with aortic stenosis is a "red flag" for future adverse events. We classified patients undergoing transcatheter aortic valve implantation (TAVI) into those with acute, prior, or no prior CD at the timepoint of TAVI and compared their clinical presentation, prognosis, and effects of the prescribed medication during follow-up.

Methods: Retrospective analysis of patients of one center fulfilling the criteria of 30-day device success after transfemoral TAVI.

Comparison of the New-Generation Self-Expanding NAVITOR Transcatheter Heart Valve with Its Predecessor, the PORTICO, in Severe Native Aortic Valve Stenosis.

Background: Third-generation transcatheter heart valves (THVs) are designed to improve outcomes. Data on the new intra-annular self-expanding NAVITOR are scarce.

Aims: The aim of this analysis was to compare outcomes between the PORTICO and the NAVITOR systems.

Incidence and predictors of hemodynamic compromise due to high-grade AV block after TAVI.

Background: High-grade AV block (HAVB) is the most frequent adverse event after transcatheter aortic valve implantation (TAVI). In rare cases, HAVB is associated with hemodynamic compromise (HC) followed by syncope or application of cardiopulmonary resuscitation (CPR), but data on this severe complication are scarce. The aim of the present study was to investigate the incidence and predictors of HC due to HAVB in patients undergoing TAVI.

Transcatheter Aortic Valve Replacement in Patients With Reduced Ejection Fraction and Nonsevere Aortic Stenosis.

Background: The potential benefit of transcatheter aortic valve replacement (TAVR) in patients with nonsevere aortic stenosis (AS) and heart failure is controversial. This study aimed to assess outcomes of patients with nonsevere low-gradient AS (LGAS) and reduced left ventricular ejection fraction undergoing TAVR or medical management.

Methods: Patients undergoing TAVR for LGAS and reduced left ventricular ejection fraction (<50%) were included in a multinational registry.
