Filter by:The purpose of this study is to conduct a clinical investigation of the Foldax Tria Aortic Valve to collect evidence on the device's safety and performance.
This study aimed at comparing the performance of self-expandable valves versus balloon-expandable valves in patients with ascending aortic dilation undergoing transcatheter aortic valve replacement.
To evaluate the safety and feasibility of DurAVR™ THV System in the treatment of subjects with symptomatic severe native aortic stenosis.
Aortic valve sclerosis (aortic valve thickening and calcification without pressure gradient) is one of the most common valvular abnormalities in the Western world. Per year, about 1.8-1.9% of these patients develop aortic valve stenosis which will eventually be treated by TAVI (Transcatheter aortic valve implantation). The purpose of this study is to collect and monitor ongoing safety and performance clinical data of the ACURATE neo2™ aortic bioprosthesis and the ACURATE neo2™ transfemoral delivery system, hereafter referred to as the ACURATE neo2™ and transfemoral delivery system in the context of an observational investigator initiated trial (IIT).
Clinical trial to evaluate the early safety and efficacy of the transfemoral implant of Inovare® Transcatheter Valve for the treatment of patients with severe degenerative aortic stenosis and high surgical risk.
Aortic stenosis (AS) is characterised by left ventricular (LV) hypertrophy and altered myocardial substrate metabolism. Peroxisome proliferator-activated receptor (PPARα), a regulator of lipid metabolism is deactivated in pressure overload hypertrophy such as in AS and can lead to dysregulation of fatty acid oxidation, myocardial triglyceride accumulation (steatosis) and lipotoxicity. The investigators propose a proof-of-concept study to investigate the effect of altering myocardial triglyceride (MTG) using a PPARα agonist, fenofibrate on cardiac physiology in patients with asymptomatic moderate-severe AS. The primary endpoint is a change in MTG assessed by magnetic resonance spectroscopy at baseline and after 6 months of treatment. Exploratory endpoints are changes in cardiac physiology including myocardial deformation (strain) as assessed by cardiac magnetic resonance imaging. The investigators hypothesise that pharmacological reduction of MTG with a PPARα agonist will result in steatosis regression and changes in cardiac physiology.
The CAS study is a prospective observational cohort study investigating the effects of congenital aortic stenosis (ConAoS) on the left ventricular function and the prevalence, pattern and expanse of left ventricular hypertrophy (LVH), myocardial stiffness and myocardial fibrosis.
The objective of the study is to evaluate the safety and performance of a new non-invasive ultrasound therapy (NIUT) with Valvosoft in the treatment of Calified Aortic Stenosis
A prospective, non-randomized, single-arm, single-center, first-in-human study designed to evaluate the safety and feasibility of the DurAVR™ THV System in the treatment of subjects with symptomatic severe aortic stenosis.
A prospective, multicenter, single-arm study aimed to demonstrate safety and performance of the Leaflex™ Performer in the treatment of symptomatic severe aortic stenosis. Subjects will be seen at pre- and post procedure, discharge, 30 days and at 3, 6, 9 and 12 months post procedure.
