Filter by:The study is aiming to document the long-term safety and effectiveness of renal denervation in patients with hypertension and other diseases characterized by elevated sympathetic drive. Catheter-based renal denervation will be performed using CE marked, percutaneous, systems.
Systemic sclerosis is an orphan, multiorgan disease affecting the connective tissue of the skin and all internal organs. Cardiac involvement, mainly characterised by small intramyocardial coronary artery involvement and myocardial fibrosis, can cause the development of impaired diastolic ventricular filling, cardiac blocks and ventricular arrhythmias, and can ensue in congestive heart failure and sudden death. Until now, no drug has been proven to have a therapeutic effect on SSc myocardial disease on an evidence-based level. Short-term trials and retrospective studies have suggested a favourable and protective effect of calcium channel blockers and angiotensin converting enzyme inhibitors in patients with myocardial involvement. However, no data are presently available on the prevention and treatment of severe heart disease. This observational trial is part of the collaborative project "DeSScipher", one out of five observational trials to decipher the optimal management of systemic sclerosis. Aim of this observational trial is to assess the efficacy and safety of calcium channel blockers and angiotensin converting enzyme inhibitors in asymptomatic SSc patients with cardiac involvement.
In this pilot study the investigators will perform a double-blind randomized trial of intranasal oxytocin on measures of cardiac refractoriness, among individuals who are undergoing clinically indicated catheter ablation procedures for paroxysmal atrial fibrillation. The investigators seek to enroll 20 patients for this study, for the purpose of estimating effect sizes for a larger future study.
The main objective of the European Pediatric Catheter Ablation Registry is to collect data on ablation procedures in the European pediatric population in order to improve the management of this subset of patients.
Frequent monomorphic premature ventricular complexes (PVCs) may cause a cardiomyopathy (CMP) that is reversible by suppression of the ectopic focus. This study investigates whether PVC suppression therapy can improve cardiac function and clinical condition of patients with idiopathic or ischemic CMP and frequent monomorphic PVCs. For this purpose, patients will be randomized to either one of two treatment strategies: 1) conventional heart failure therapy plus PVC suppression therapy, consisting of RFCA as primary treatment and Amiodarone as secondary treatment in case of unsuccessful RFCA, or 2) conventional heart failure therapy without PVC suppression therapy.
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 purpose of this study is to assess efficacy of prolonged Full Disclosure ECG monitoring and signal analysis using advanced GSM telemetric technology to prescribe the most appropriate treatment of arrhythmia.
The purpose of this study is to assess efficacy of prolonged Full Disclosure electrocardiogram (ECG) monitoring and signal analysis using advanced telemetric technology to diagnose syncope in comparison with standard diagnostic procedure
This clinical investigation is a prospective, non-randomized, multi-center pivotal trial. This trial aims to validate the automatic detection features provided by the external long-duration SpiderFlash-t™ Event recorder coupled with its analyser EventScope™, and to assess the performances of the Mode Switch function provided by Sorin Group Implantable Cardioverter-Defibrillators (ICDs). This trial is being performed first in order to demonstrate the ventricular tachycardia (VT)/ ventricular fibrillation (VF) sensitivity of the automatic VT/VF detection function of the EventScope™ software. Patients will be implanted with an ICD from Sorin Group, with PARAD+ arrhythmia detection enabled and Mode Switch (MS) algorithms activated in all patients. Arrhythmic events will be documented over a period of 6 to 8 weeks for each patient.
