NCT01638897
The purpose of this study is to evaluate long-term performance of the DF4 Connector System. This evaluation is based on the number of DF4 lead-related complications occurring during the study compared to the number of leads enrolled in the study. The DF4 systems will be followed for 5 years after implant. This study is required by FDA as a condition of approval of the DF4 Connector Systems. This study is conducted within Medtronic's post-market surveillance platform.

The purpose of this study is to evaluate the effects of BMS-986231 on systolic and diastolic parameters in patients with heart failure and low ejection fraction.
NCT02053038
Narrowing of coronary arteries interferes with blood flow and can cause chest pain. But patients may have more than one narrowing and studies have shown that not all narrowings need to be treated. To identify the narrowings that need treating cardiologists sometimes quantify the extent of the narrowing by measuring fractional flow reserve (FFR, the ratio of the pressure in the aorta to the pressure downstream of the narrowing).This technique requires the administration of drugs that add cost and time to the procedure and in some countries are simply unavailable. As a result despite the clear health and healthcare costs benefits of FFR its use is limited to less than 5% of procedure. We have developed a new technique called the instantaneous wave-free ratio (iFR) that does not require the administration of drugs for its accurate assessment. It has been approved for use in this indication. This study aims to compare clinical outcomes of patients whose treatment has been guided by iFR to those whose treatment has been guided by FFR. If iFR is found to provide the same clinical outcomes as FFR its adoption will permit the clear benefits of this approach of identifying the coronary narrowings that really need treatment to be applicable to a much larger patient population and further improve healthcare costs.
NCT00632372
The purpose of this study is to collect and analyze electrical measurements, timing, and signals from a CRT-D device in heart failure patients who either already have an implanted left atrial pressure sensor or will undergo a simultaneous implantation of a left atrial pressure sensor and a CRT-D device. These devices may be placed at the same time or separately (staged procedure) at the discretion of the investigator. A comparison will be made between the information gathered from the CRT-D system and the information gathered by the left atrial pressure sensor.
NCT02833948
The aortic valve is located between the left ventricle and the aorta. Patients with symptomatic, severe aortic valve stenosis conventionally have it surgically replaced requiring direct access to the heart through the chest. Transcatheter aortic valve replacement (TAVR) is now a well-established alternative for treating severe aortic valve stenosis. Both types of intervention improve prognosis and alleviate symptoms. The optimal choice of blood thinning therapy after TAVR is unknown. It has been reported that leaflet thrombosis with reduced leaflet motion can occur and this phenomenon has been suggested to be potentially related with neurological events. In addition, the occurence of this phenomenon can be reduced with anticoagulation blood thinning therapy. The purpose of this study is to evaluate if anticoagulation compared to the usual double platelet inhibitor therapy after TAVR can reduce the risk of leaflet thrombosis.
NCT00807040
People with coronary artery disease (CAD) or people who have had a heart attack may develop a leak in the mitral valve of their heart and may therefore need to undergo surgery to fix the valve. The best way to fix the mitral valve remains undetermined. This study will evaluate whether it is better for people with severe mitral valve leakage to undergo a mitral valve replacement procedure or a mitral valve repair procedure.
NCT00115349
The purpose of this study is to determine whether left ventricular function improves more rapidly with deferoxamine (DFO) and deferiprone (L1) combination therapy than with DFO monotherapy in patients with thalassemia and decreased ejection fractions. Secondary aims include evaluating changes in myocardial iron burden using T2\* and estimating the relative incidence and severity of chelator-induced toxicity.
NCT01953874
The aim of the study is to compare the effects of MV targeted ASV in addition to optimized medical therapy versus optimized medical therapy alone at 6 months in patients with acute decompensated HF. The study will also assess changes in functional parameters, biomarkers, quality of life (QOL), and sleep.
NCT01560780
This is a randomized-controlled clinical trial that will randomize 120 patients undergoing clinically-indicated coronary artery bypass graft surgery to prasugrel at a dose of 10 mg daily or matching placebo for 12 months, starting at the time of hospital dismissal from surgery. The primary goal of the study is to determine whether prasugrel administration will prevent thrombus (clot) formation within a saphenous vein graft at 12 months, as examined by optical coherence tomography.
NCT01826019
The overall objective of the HOPE-4 Phases (HT and CVD) is to develop, implement and evaluate an evidence-based, contextually appropriate programme for cardiovascular disease (CVD) risk assessment, treatment and control involving: (1) simplified algorithms implemented by non-physician health workers (NPHW) and supported by e-health technologies (tablets programmed with decision and counselling support software); (2) initiation of evidence-based cardiovascular (CV) medications and (3) treatment supporters to optimize long-term medication and lifestyle adherence.
NCT02996903
The "Prospective Multicenter Registry On RadiaTion Dose Estimates Of Cardiac CT AngIOgraphy IN Daily Practice in 2017" (PROTECTION-VI) study is a prospective registry and investigator-initiated initiative without third-party funding, which will collect and analyze the radiation dose exposure of Cardiac Computed Tomography Angiographic (CCTA) studies in current daily practice worldwide. Particularly, the study will assess the use of strategies for dose reduction during CCTA. A decade ago, the multicentre observational PROTECTION-I study has revealed that the dose-length-product of CCTA ranges between 568 - 1259 mGy x cm with a median of 885 mGy x cm. This corresponds to an estimated effective dose of approximately 12 mSv. Since then a variety of techniques have been developed and enhanced in order to reduce radiation exposure during CCTA. Recent studies demonstrated feasibility of dramatically reduced effective radiation doses during CCTA (0,1 - 0,3 mSv). This has been executed in small cohorts of patients at scientific expert centers. However, it remains unclear, if such low-level radiation dose exposure may be achieved in clinical routine and if diagnostic image quality is maintained. In order to analyze the magnitude of radiation dose exposure of CCTA in today's clinical practice and the current use of dose-saving techniques, we designed the PROTECTION-VI study. Eventually, this study may contribute to further improving radiation dose exposure for patients undergoing CCTA.
NCT00554671
