Article Synopsis
  • The study investigates the effects of immediate and delayed increases in mean gradient elevation after transcatheter aortic valve implantation (TAVI), using data from the FRANCE 2 registry involving 4201 patients with severe aortic stenosis.
  • Three patient groups were analyzed based on their post-procedural mean transvalvular gradient (PPMG) and delayed mean gradient increase (DMGI): control (normal gradients), Group 1 (normal with delayed increase), and Group 2 (elevated gradients).
  • Findings revealed that patients with PPMG ≥ 20 mmHg experienced significantly higher 4-year mortality compared to controls, while those with PPMG < 20 mmHg developed DMGI showed similar outcomes

Article Synopsis
  • A study analyzed data from French TAVR registries to compare long-term outcomes in patients using direct oral anticoagulants (DOACs) versus vitamin K antagonists (VKAs) after transcatheter aortic valve replacement (TAVR).
  • The research found that patients on DOACs experienced lower mortality and major bleeding rates after three years compared to those on VKAs, although rates of ischemic events were similar between the two groups.
  • The findings suggest that DOACs may be the preferred choice for oral anticoagulation therapy in TAVR patients, promoting better long-term safety and efficacy.

November 2019

Univ. Lille, CNRS, CHU Lille, UMR 9193 - SCALab - Sciences Cognitives et Sciences Affectives, F-59000 Lille, France5.

A substantial body of research has assessed the effect of gender on face recognition; however, little is known about the effect of relationship status on face recognition. In this study, we assessed for the first time how relationship status impacts face recognition by asking 62 male and female participants to decide whether they had previously encountered faces of males and females. Participants were also asked to fill a socio-demographic variables questionnaire which included, among other information, question about their relationship status (i.

Background: Accurate risk stratification is pivotal for appropriate selection of patients with severe symptomatic aortic stenosis for either surgical or transcatheter aortic valve replacement (TAVR). We sought to determine whether recent risk prediction models developed specifically in TAVR patients enhance prognostication in comparison with previous surgical scores used in clinical practice (EuroScore I, EuroScore II, STS).

Methods: The Israeli TAVR Registry Risk Model Accuracy Assessment (IRRMA) study utilized a multicenter prospective TAVR database (n=1327) to perform a quantitative comparison between previous risk scores developed in either surgical or TAVR populations, with the present registry serving as an independent external validation set.

Patients with aortic stenosis tend to develop ventricular conduction problems, which are known adverse events following transcatheter aortic valve implantation (TAVI). Changes in ventricular conduction status after TAVI were analyzed in 195 consecutive patients from a single institute registered in FRANCE2 between February 2010 and June 2012. Among the 195 patients, 29 had a prior pacemaker implantation (+PM) and 6 had acute catastrophic hemodynamics that made a full electrocardiogram (ECG) unavailable.
