Filter by:Anticoagulants are used to prevent thrombotic events in patients with predisposing factors. However, the use of such therapies is associated with bleeding complications, which can be a serious safety issue. Thus, it is important to evaluate the safety and effectiveness of such therapies based on data collected in clinical practice in order to generate relevant scientific data that could be used to support clinical and regulatory decisions. This is an open, prospective, multicenter, observational cohort study that aims to prospectively record the clinical history of adult patients receiving anticoagulant treatment, irrespectively of the prescribed drug and the indication for its use.
The primary purpose of this study is to evaluate the diagnostic performance of three methods for measuring right ventricular size and function including the Philips Novel RV quantification technologies (RV Heart Model volumetric analysis and Philips 2D strain) and the Upper Valley Right Ventricle Algorithm (UVRV) algorithm as compared to the gold standard of volumetric analysis via cardiac magnetic resonance imaging (CMR) in a broad patient population.
The primary objective of this study is to evaluate the rate of deep sternal wound infection at 30 days post-operative following a full median sternotomy in patients treated with SternaLock Blu for rigid sternal fixation. This study will also provide evidence of the clinical performance of SternaLock Blu for up to 90 days using real world evidence methodology. Sternal complications will be reported through 90 days follow up.
The primary objective of the study is to generate feasibility safety and performance data for the 4Tech TriCinch Coil System in symptomatic patients suffering from moderate to severe functional tricuspid regurgitation with annular dilatation. The TriCinch Coil System is a percutaneous catheter-based medical device for tricuspid valve repair.
The prevalence of valvular heart disease is on the rise along with the aging society and the generalization of echocardiography. Furthermore, the rheumatic valvular heart disease is much more prevalent in Asia than in Western countries, and the frequency of valve disease is higher in Asia. The effect of an implantable cardioverter defibrillator (ICD) in the primary prevention of sudden cardiac death in ischemic cardiomyopathy is well established and has become a standard of care. However, there is limited research on the effect of ICD implantation for primary prevention in patients with heart failure due to valvular heart disease. In a small study, the incidence of fatal cardiac arrhythmia was lower in patients with valvular cardiomyopathy (5%) who received ICD implantation for primary prevention than in those with ischemic cardiomyopathy. But there is also a report that the appropriate ICD treatment is not different from that of ischemic heart disease in valvular heart disease patients. Therefore, it is necessary to study the primary prevention effect of ICD on valvular cardiomyopathy in a larger number of patients. The purpose of this study was to investigate the effect of ICD on the prevention of sudden cardiac death in patients with heart failure due to valvular heart disease through prospective, multicenter, and observational studies.
Mechanical heart valves (MHV) demand lifelong anticoagulation with vitamin K antagonists (VKA) due to the high thrombogenicity of the prosthesis. Rivaroxaban has previously been tested in experimental and animal models with encouraging results. The investigators recently sent for publication an experiment with 7 patients who used rivaroxaban in metallic prosthesis with encouraging results. In this way it was decided to do a randomized non-inferiority clinical trial comparing rivaroxaban with warfarin in patients with metallic prosthesis.
The objective of this study is to evaluate feasibility, safety and effectiveness of the first generation transfemoral JenaValve Pericardial TAVR System (formerly named JenaValve TAVI Plus System- Transfemoral) in an elderly patient population with severe aortic stenosis who are at high risk for surgical aortic valve replacement.
Coronary artery bypass grafting (CABG) is the most common procedure performed by cardiac surgeons. Post-operative atrial fibrillation (AF) is the most common adverse event following CABG, experienced in 20-50% of patients; the highest incidence of AF occurs by the third post-operative day. Reduction of AF by various drugs is moderately effective, but involves either rate control with beta blockers or rate conversion with amiodarone after the myocardial damage processes initiating AF have already occurred. Decreasing the incidence of post-operative AF, and hence the morbidity and mortality of high-risk CABG patients, could be more fruitfully approached by targeting the upstream combined processes of inflammation and coagulation activation induced by the surgical insult and associated ischemia-reperfusion (I/R). We propose that cell damage induced by oxidative stress and I/R injury could be prevented and/or inhibited by antioxidant supplementation. Specifically the investigators hypothesize that high-dose intravenous (IV) vitamin C supplementation will ameliorate ROS and therefore damp down upstream inflammatory processes, leading to a reduction of downstream adverse events with demonstrable links to inflammation processes, such as AF.
The Cardioband Transcatheter System (Cardioband) is indicated for the treatment of secondary (functional) mitral regurgitation (FMR). The Cardioband is a transcatheter system, deployed on the beating heart through a transseptal approach. The Cardioband is deployed along the posterior annulus of the mitral valve (MV) and is adjusted under trans-esophageal guidance on the beating heart. A CE mark study with 30 subjects has been completed and documented reduction of severity of mitral regurgitation (MR) and improvement in 6- minute walk test in subjects with moderate to severe MR. Study objectives are to test the efficacy of the Cardioband in improving MR and heart failure symptoms in patients with symptomatic (New York Heart Association (NYHA) Class III-IVa), severe MR in the post-marketing setting, And to evaluate the safety of the Cardioband system in the post-marketing setting.
The purpose of this study is to determine whether Sildenafil is effective in the treatment of sustained pulmonary artery hypertension after corrected mitral valve disease.
