Initial Multicenter Experience With a Novel Self-Expanding TAVR System in Patients With Aortic Valve Stenosis.
JACC Cardiovasc Interv
January 2025
Clinic for General and Interventional Cardiology/Angiology, Herz- und Diabeteszentrum NRW, Ruhr-Universität Bochum, Bad Oeynhausen, Germany. Electronic address:
Background: As transcatheter aortic valve replacement is performed increasingly in younger, low-risk patients, the need for commissural alignment and coronary access has increased. Design elements of the JenaValve Trilogy (JVT) transcatheter heart valve (THV) ensure both.
Objectives: This study sought to evaluate the outcome of patients with aortic stenosis (AS) treated with this novel transfemoral, self-expanding THV.
Parametric finite element modeling of reinforced polymeric leaflets for improved durability.
J Mech Behav Biomed Mater
January 2025
School of Materials Science and Engineering, Colorado State University, 700 Meridian Ave, Fort Collins, 80523, CO, USA. Electronic address:
Hyaluronic acid-enhanced polyethylene polymeric TAVR shows excellent in vivo anti-calcific, anti-thrombotic, and in vitro hydrodynamic performance. However, during durability testing, impact wear and fatigue cause early valve failure. Heart valve durability can be improved by strengthening the leaflet with fiber reinforcement.

Laryngoscope
January 2025
Department of Otolaryngology-Head and Neck Surgery, Louisiana State University Health Sciences Center, Shreveport, Louisiana, U.S.A.
Objective: To identify the most effective treatment modality for achieving favorable outcomes in early glottic tumors with anterior commissure involvement (ACI).
Data Sources: PubMed, Embase, Web of Science, and ScienceDirect.
Review Methods: Random-effects proportional meta-analysis model is used to evaluate the oncological and functional outcomes of transoral laser microsurgery (TLM) versus radiation therapy (RT) in early glottic (T1-T2) cancer with ACI.
A detailed spatiotemporal atlas of the white matter tracts for the fetal brain.
Proc Natl Acad Sci U S A
January 2025
Computational Radiology Laboratory, Boston Children's Hospital, Boston, MA 02115.
This study presents the construction of a comprehensive spatiotemporal atlas of white matter tracts in the fetal brain for every gestational week between 23 and 36 wk using diffusion MRI (dMRI). Our research leverages data collected from fetal MRI scans, capturing the dynamic changes in the brain's architecture and microstructure during this critical period. The atlas includes 60 distinct white matter tracts, including commissural, projection, and association fibers.

Curr Opin Otolaryngol Head Neck Surg
December 2024
Purpose Of Review: To summarize current evidence regarding the indication of adjuvant treatment after transoral laser microsurgery (TOLMS).
Recent Findings: Apart from well known risk factors, margins represent the key point in the decision-making. If margins are affected, additional treatment is mandatory.
