NCT ID: NCT01580436 Recruiting - Clinical trials for Tricuspid Valve Insufficiency

Prophylactic Tricuspid Valve Annuloplasty in Patients Undergoing Mitral Valve Surgery

Start date: August 2011
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT01574053 Recruiting - Clinical trials for Huntington's Disease

Enroll -HD: A Prospective Registry Study in a Global Huntington's Disease Cohort

Start date: July 2012
Phase:
Study type: Observational [Patient Registry]

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.

NCT ID: NCT01560897 Recruiting - Clinical trials for Disorder of the Urea Cycle

Investigating Project of the Functional C13 Test "Pilot Study"

PIL001
Start date: January 2012
Phase: Phase 1/Phase 2
Study type: Interventional

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"

NCT ID: NCT01547208 Recruiting - Clinical trials for Ventricular Tachycardias

Does Timing of VT Ablation Affect Prognosis in Patients With an Implantable Cardioverter-defibrillator?

PARTITA
Start date: September 2012
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT01542580 Recruiting - Clinical trials for Rheumatoid Arthritis

A Prospective, Clinical Investigation of the Vanguard 360 Revision Knee

Start date: March 2012
Phase:
Study type: Observational

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.

NCT ID: NCT01535625 Recruiting - Clinical trials for Coronary Artery Disease

Safety and Effectiveness of the Coronary Momo Stent

Start date: February 2012
Phase: Phase 4
Study type: Interventional

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.

NCT ID: NCT01524510 Recruiting - Clinical trials for Obstructive Sleep Apnea Syndrome

Validation of Functional Imaging as Predictive Tool for Outcome of Mandibular Replacement Appliance Therapy in Obstructive Sleep Apnea Hypopnea Syndrome Patients

Start date: February 2011
Phase: Phase 4
Study type: Interventional

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.

NCT ID: NCT01524276 Recruiting - Clinical trials for Coronary Artery Disease

Product Surveillance Registry

PSR
Start date: January 2012
Phase:
Study type: Observational

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.

NCT ID: NCT01522430 Recruiting - Clinical trials for Resistant Hypertension

Study of Catheter Based Renal Denervation Therapy in Hypertension

DEPART
Start date: January 2012
Phase: Phase 3
Study type: Interventional

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.

NCT ID: NCT01522183 Recruiting - Clinical trials for Atypical Hemolytic-Uremic Syndrome

Atypical Hemolytic-Uremic Syndrome (aHUS) Registry

Start date: April 30, 2012
Phase:
Study type: Observational [Patient Registry]

Post-marketing safety data on patients treated and untreated with eculizumab or ravulizumab.
