NCT05386173
In one of the most severe congenital heart defects, hypoplastic left heart syndrome (HLHS), the left ventricle is underdeveloped and the prognosis is worse than in most other heart defects. The underdevelopment can occur gradually during fetal growth caused by a narrowing of the aortic valve. At some international centers, such fetuses are treated with a balloon dilation of the narrowed valve, but there is no scientifically sound evidence that this treatment is effective. The aim of this study is: 1/ to evaluate whether balloon dilation during the fetal period of a narrowed aortic valve can reduce the risk of the left ventricle becoming underdeveloped and the baby being born with a so-called univentricular heart (HLHS); 2/ to investigate whether such treatment improves the prognosis for this group of children with a very complex and severe heart defect and 3/ to also describe side effects and risks in fetuses and mothers of the fetal procedure.
NCT04766892
This is a Phase 2a proof-of-concept study to assess safety, tolerability, and preliminary efficacy of mavacamten treatment on biomarker levels in participants with heart failure with preserved ejection fraction (HFpEF) and elevation of NT-proBNP with or without elevation of cTnT. Data from this study will inform future study designs of mavacamten in patients with HFpEF.
NCT03988634
The effect of sacubitril/valsartan vs. valsartan on changes in NT-proBNP, safety, and tolerability in HFpEF patients with a WHF event (HFpEF decompensation) who had been stabilized and initiated at the time of or within 30 days post-decompensation.
NCT04089059
This is a prospective, open- label, single arm, multicenter clinical trial to evaluate the safety and effectiveness of the Cordella PA Sensor System in NYHA Class III Heart Failure Patients compared to a Performance Goal (PG).
NCT03533517
This is a non-randomized, prospective, multi-center Early Feasibility Study to evaluate the AccuCinch® Ventricular Restoration System in Patients with Heart Failure and Reduced Ejection Fraction (HFrEF).
NCT02787785
The MADIT S-ICD trial was designed to evaluate if subjects with a prior myocardial infarction, diabetes mellitus and a relatively preserved ejection fraction of 36-50% will have a survival benefit from receiving a subcutaneous implantable cardioverter defibrillator (S-ICD) when compared to those receiving conventional medical therapy. The trial enrollment was stopped in 2018 due to lower than expected enrollment, all subjects enrolled at that time were followed for approximately 5 years.
NCT03719040
The Physiologic Pacing Registry is a prospective, observational, multi-center registry performed to gain a broader understanding of 1) physiologic pacing implant and follow-up workflows, including pacing and sensing measurements and 2) the clinical utility in creating a 3-dimensional electro-anatomical map of cardiac structures prior to physiologic pacing device implants based on the clinical site's routine care.
NCT04356027
The purpose of the FUSION study is to validate the diagnostic performance of Virtual Flow Reserve (VFR) by comparing it against a reference standard, fractional flow reserve (FFR).
NCT05001009
The long term goal is to improve quality of care in Veterans with serious illnesses by aligning medical care with Veterans' goals and values. The objective of this study is to use a sequentially randomized trial to determine what implementation strategies are effective to increase early, outpatient goals of care conversations. The study will use interviews with and surveys of medical providers, patients, and caregivers, along with medical record data. This work is significant because it tests ways Veterans can express their goals and preferences for life sustaining treatments and have them honored.
NCT04378179
The study will test the ability a novel wearable sensor based on a smartphone app (Precordior CardioSignal app) in combination with a sensor device (Suunto Movesense sensor) to non-invasively measure cardiac motion and function.
NCT06424834
The goal of this clinical trial is to learn if targeted medical therapy will improve symptoms and quality of life in patients with angina and non-obstructive coronary arteries compared to placebo, after the underlying cause of the chest pain has been ascertained by coronary function testing. Participants will be treated with either medications that target the underlying cause of their chest pain or placebo for 4 weeks after a drug titration phase of 1-3 weeks. They will be asked to complete a series of questionnaires to evaluate their quality of life at the beginning and end of the study.
NCT01426425
ICY-AVNRT (Intracardiac CrYoablation for AtrioVentricular Nodal Reentrant Tachycardia) is a prospective multi-center, nonrandomized, single arm, controlled, unblinded, investigational clinical study. The purpose of this clinical study is to demonstrate the safety and effectiveness of the Freezor® Xtra Cardiac CryoAblation Catheter for the cryoablation of the conducting tissues of the heart in the treatment of patients with atrioventricular nodal reentrant tachycardia (AVNRT) using an endocardial approach.
NCT04167761
The purpose of this study is to learn if Sodium-Glucose Cotransporter 2 inhibitor (SGLT2i) medications enhance beneficial properties of epicardial adipose tissue including metabolic flexibility, insulin sensitivity, decreased cell size and reduced inflammation.
NCT03541603
Phase 2 study to evaluate the efficacy and safety of intermittent levosimendan compared with placebo in hemodynamic improvement with exercise in PH-HFpEF subjects
NCT02178943
Plasma donor-derived cell-free DNA (dd-cfDNA) is measured as a % of the total plasma cfDNA in association with the measurement of AlloMap, a non-invasive gene expression test to aid in heart transplant management.
NCT00826280
Observe whether the administration of caffeine prior to regadenoson will affect the interpretation of test results in subjects with coronary artery disease (CAD) undergoing SPECT MPI
NCT04096040
To assess investigator engagement of μCor system data in the context of heart failure management. The μCor system includes a sensor and wearable patch for fluid management.
NCT03153111
This is a study to evaluate whether macitentan is an effective and safe treatment for patients with heart failure with preserved ejection fraction (HFpEF) and pulmonary vascular disease. The primary objective is to evaluate whether macitentan 10 mg reduces N-terminal pro-brain natriuretic peptide (NT-pro-BNP) as compared to placebo in these patients.
NCT04451044
Multi-center, prospective, randomized controlled study comparing PCI guided by angiography versus iFR Co-Registration using commercially available Philips pressure guidewires and the SyncVision co-registration system, employing an adaptive design study for interim sample size re-estimation.
NCT02806570
This is a multi-center, non-randomized, prospective Early Feasibility Study to evaluate the AccuCinch® Ventricular Restoration System in patients with symptomatic heart failure and concomitant functional mitral regurgitation that have stable symptoms on guideline-directed medical therapy
