There are about 13446 clinical studies being (or have been) conducted in Belgium. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
De novo or progressive tricuspid regurgitation (TR) is not uncommonly observed following mitral valve surgery and associated with worse outcome. Hence, concomitant tricuspid valve annuloplasty (TVP) has been recommended for patients undergoing mitral valve surgery when tricuspid annular dilatation is present even in absence of significant TR. However, whether such a strategy of "prophylactic TVP" results in improved outcomes has not been shown to date by a prospective randomized study. The investigators goal is therefore to initiate such a study and evaluate the effect of concomitant TVP on mid- and long-term outcome in patients scheduled for mitral valve surgery and tricuspid annular dilatation but <2+ TR.
Enroll-HD is a longitudinal, observational, multinational study that integrates two former Huntington's disease (HD) registries-REGISTRY in Europe, and COHORT in North America and Australasia-while also expanding to include sites in Latin America. More than 30,000 participants have now enrolled into the study. With annual assessments and no end date, Enroll-HD has built a large and rich database of longitudinal clinical data and biospecimens that form the basis for studies developing tools and biomarkers for progression and prognosis, identifying clinically-relevant phenotypic characteristics, and establishing clearly defined endpoints for interventional studies. Periodic cuts of the database are now available to any interested researcher to use in their research - visit www.enroll-hd.org/for-researchers/access-data/ to learn more.
The aim of this pilot study is to evaluate the validity and reproducibility of a functional test "Test C13" ureogenesis to measure in vivo, using the methodology Laboratory of Metabolic Diseases of "Cliniques Universitaires Saint-Luc"
The purpose of this study is to assess whether the burden of untreated non-sustained ventricular tachycardias (VTs), or episodes treated with anti-tachycardia pacing, correlates with appropriate implantable cardiac defibrillator (ICD) shock therapies and to evaluate if the timing of radiofrequency VT ablation affects the prognosis of ICD recipients.
The purpose of this study is to evaluate performance of the Vanguard 360 revision knee system utilizing offset on either the tibial component, femoral component, or both in terms of the restoration of mechanical alignment, clinical outcomes and survivorship.
This study evaluates the safety and effectiveness of the Momo Cobalt Chromium stent system for the treatment of single de novo lesions in a native coronary artery. The stent is coated with diamond-like carbon to decrease the risk of acute and late stent thrombosis, to increase the resistance towards corrosion and to significantly improve endothelialisation through the inhibition of elution of metallic ions.
In this open prospective study 40 patients who received Mandibular Replacement Appliance (MRA) Therapy as treatment of Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) will be included. The patient's sleep will be registered during 2 periods of 2 days: one while the patient does not wear the MRA and, +/- 1 week later, one while the patient wears the MRA. Furthermore, 2 low dose CT scans (one with and one without the MRA device in the mouth) will be taken. These data must allow the investigators to validate the use of functional imaging (segmentation and Computational Fluid Dynamics) as a predictor of the outcome of the MRA therapy in OSAHS patients.
The purpose of the Registry is to provide continuing evaluation and periodic reporting of safety and effectiveness of Medtronic market-released products. The Registry data is intended to benefit and support interests of patients, hospitals, clinicians, regulatory bodies, payers, and industry by streamlining the clinical surveillance process and facilitating leading edge performance assessment via the least burdensome approach.
The DEPART study end points are to provide conclusive evidence, using a randomized, double blinded, sham procedure controlled study design, that radiofrequency renal denervation: 1. reduces daytime ambulatory blood pressure, 2. improves nocturnal dipping in blood pressure at the ambulatory blood pressure recording.
Post-marketing safety data on patients treated and untreated with eculizumab or ravulizumab.
