Active clinical trials for "Aortic Valve Stenosis"

The diagnosis of valvular heart disease (VHD), or its absence, invariably requires cardiac imaging. A familiar and inexpensive tool to assist in the diagnosis or exclusion of significant VHD could both expedite access to life-saving therapies and reduce the need for costly testing. The FDA-approved Eko Duo device consists of a digital stethoscope and a single-lead electrocardiogram (ECG), which wirelessly pairs with the Eko Mobile application to allow for simultaneous recording and visualization of phono- and electrocardiograms. These features uniquely situate this device to accumulate large sets of auscultatory data on patients both with and without VHD. In this study, the investigators seek to develop an automated system to identify VHD by phono- and electrocardiogram. Specifically, the investigators will attempt to develop machine learning algorithms to learn the phonocardiograms of patients with clinically important aortic stenosis (AS) or mitral regurgitation (MR), and then task the algorithms to identify subjects with clinically important VHD, as identified by a gold standard, from naïve phonocardiograms. The investigators anticipate that the study has the potential to revolutionize the diagnosis of VHD by providing a more accurate substitute to traditional auscultation.

This registry is designed to quantify embolic debris capture rate in patients at low surgical risk treated with the Sentinel System during TAVI.

The FinnValve investigators planned a nationwide registry to investigate the early and late outcome of transcatheter aortic valve implantation (TAVI) compared to surgical aortic valve replacement (SAVR) in patients with aortic valve stenosis performed from 2008 to 2017 at five Finnish University Hospitals. Data will be collected in a dedicated electronic case report form.

The Early neo2 registry will study up to 500 patients treated with the updated Boston Acurate neo2 TAVI prosthesis at various European hospitals. The data is gathered from routine healthcare and there are no study-mandated additional procedures. The main endpoint is a combined efficiency and safety endpoint after 30 days. Imaging data (echocardiography, computed tomography and aortography) will be analysed centrally by a core lab.

This study plans to investigate the relationship between cognitive status pre-procedure, and clinical outcomes at 3 months in patients undergoing transcatheter aortic valve implantation (TAVI).

Non-contrast enhanced cardiac MRI using 3D whole heart acquisition protocol is non-inferior to contrast enhanced CT in the assessment of aortic annulus complex for pre-TAVR imaging.

Retrospective, observational study to compare the outcomes of patient receiving TAVI through transfemoral and transaxillary fully percutaneous approach adjusting for main baseline differences.

Use of the closure device in patient with percutaneous transfemoral aortic valve replacement

Aortic stenosis (AS) is the most frequent valvulopathy in the general population in France and more generally in developed countries, due to populations aging. Its standard treatment is historically surgical aortic valve replacement (SAVR). In the 2000s, the management of this valvulopathy was revolutionized by the development of the technique of per-cutaneous aortic valve replacement (TAVI). TAVI opens the possibility of curative treatment to patients at high operational risk not operable by conventional surgery, and for whom outcome was affected with high mortality under medical treatment alone. Amyloidosis, a pathology with multiple etiologies, is a rare condition and its cardiac form (AC) even more (8 to 17 / 100,000 people / year). However, its prevalence is increasing. Some autopsies series have found prevalence up to 50% of cardiac amyloidosis with transthyretin (AC-TTR) after 60 years. In addition, recent data suggested that AC-TTR prevalence is higher in the population of patients with heart disease: 13% in heart failure with preserved ejection fraction and up to 16% in patients with AS. The outcome of patients with AC-TTR remains unknown after TAVI. Thus, the diagnosis of AC-TTR in patients undergoing TAVI represents an important issue. Indeed, a treatment stabilizing the process of accumulation of transthyretin deposits, effective on the survival of these patients, is now available. In addition, a non-invasive screening strategy for AC-TTR, alternative to biopsy, is now validated.

The study is designed as a retrospective, international, multi-center cohort study to evaluate Steelex® Sternum Set for sternum closure. The data from 2 clinics located in Germany and Spain participating in the "OPTICABG" as well as in the "PREMIVALVE" study will be used for assessment. Only patients receiving a complete or a partial sternotomy closed with Steelex® Sternum Set will be included in the analysis. "OPTICABG" patients were followed up 3 months after surgery and "PREMIVALVE" patients until 6 months after surgery. Adverse Events (AE) / Serious Adverse Events (SAE)(e.g. surgical site infection, sternum stability, stroke, myocardial infraction, death etc.) reported in both studies will be used for the STERCCAS analysis.
