Filter by:The goal of this clinical trial is to learn about the safety and performance of the F2 device for cerebral embolic protection in participants with symptomatic aortic stenosis undergoing a Transcatheter Aortic Valve replacement procedure. Participants will complete several neurocognitive assessments and an MRI procedure.
Study design: single arm, interventional and multicenter study. The objectives are evaluate Safety and efficacy of TAVI in Department of Cardiology without on site cardiac Surgery for symptomatic severe aortic valve stenosis by expert operator team, in patients with prohibitive surgical risk. For the pilot phase, 20 patients will be enrolled. For whole study, all consecutive patients undergoing TAVI in center without CS on site will be enrolled to reach a number of about 200 patients.
The goal of this clinical trial is to learn about the safety and performance of the F2 device for cerebral embolic protection in participants with symptomatic aortic stenosis underdoing a Transcatheter Aortic Valve replacement procedure. Participants will complete several neurocognitive assessments and an MRI procedure.
In this study the investigators aim to examine the role that fibrosis plays in heart conditions such as aortic stenosis , chemotherapy-induced cardiotoxicity and carcinoid syndrome . Fibrosis is a common final result following any injury to the heart muscle and the investigators aim to identify this process early and in its active state. This will be examined by using a radiotracer 68Ga-FAPI or 18F-AlF-FAPI and PET-MRI or PET-CT.
The goal of this observational study is to assess the changes of ascending aortic diameter in patients undergoing transcatheter aortic valve replacement. The main questions it aims to answer are: 1. whether the ascending aortic diameter increases or remains stable after transcatheter aortic valve replacement, especially in patients with preoperative ascending aortic dilatation; 2. the determinants of postoperative ascending aortic dilatation.
The purpose of this study is to evaluate the efficacy, safety and tolerability of pelacarsen (TQJ230) administered subcutaneously once monthly compared to placebo in slowing the progression of calcific aortic valve stenosis.
Patients with severe aortic stenosis accepted for transcatheter intervention or open surgery are included before the intervention, and then followed up with clinical visits during the first year after intervention. Imaging with echocardiography and computed tomography (CT) are performed together with additional imaging with magnetic resonance imaging (MRI) and Positron emissions tomography (PET)-CT in a subgroup of the study population. Blood samples, physical performance and questionnaires with focus on frailty and heart failure are also collected at each visit. A follow up with information of the outcomes after 2-5 years will be performed through national registries.
This trail is for patients with mild cognitive impairment (MCI) who are receiving a transcatheter aortic valve replacement (TAVR). We will assess changes in neurocognition following TAVR with the 5 minute Montreal Cognitive Assessment (mini MoCA) when comparing pre procedure with post procedure assessments.
The aorta distributes cardiac stroke volume into the whole body through its finetuned conductance function, that is propagation and modulation of flow pattern. Physicomechanic properties of the aortic wall assure continuous and homogenous blood flow distribution to organs. The physicomechanic properties of the aortic wall are heterotopic: The collagen/elastin ratio doubles in the abdominal aorta as compared to the thoracic aorta. Malfunction of aortic conduction due to large artery stiffening (LAS) leads to premature wave reflection and excess pulsatility which translate into organ damage in low-resistance beds. The regional heterogeneity of aortic physicomechanic properties and their histomorphological substrate leading to altered regional hemodynamics are not well investigated. Within the PHaRAo population, there is a spectrum of higher and lower risk patients. The aim of this cohort study is to collect prospectively and systematically clinical research data from PHaRAo patients. This cohort study is an open-end observational study to identify master switches in aortic disease
• The aim of 3DP-FAST study is to analyze the accuracy of replicating cardiovascular anatomical structures using different techniques and to evaluate the feasibility of 3D printed models of aortic stenosis in guiding TAVI procedure. By conducting a comparative analysis of measurements achieved on CCTA images versus measurements obtained with a specialized projection platform by photogrammetry vs 3D printed models of various aortic valvular and perivalvular structures will be evaluated the accuracy of each step of image dataset processing. Furthermore, the study will evaluate the rate of valvular leak or peri-procedural complications such as embolic events or atrio-ventricular conduction block based on coronary computed tomography angiographic and ECG assessment at 1 year after enrollment.
