Open label trial of letermovir prophylaxis for those heart transplant recipients at risk of cytomegalovirus infection and disease

Heart failure is a harmful disease that is associated with high avoidable moribidity that can be treated with a cardiac resynchronization therapy device (CRT-D). Previous studies have shown links between CRT-D implants and reduced rates of morbidity in patients with heart failure with left bundle branch blockages (LBBB). However, there is limited amounts of evidence for the success of heart failure patients with non-LBBB. This prospective, multi-center study is looking at heart failure patients with non-LBBB that are implanted with CRT-D. 

The primary goal of this study is to use the WHOOP fitness band as a way to measure heart rate variability (HRV) in patients with coronary artery disease (CAD) and to establish a change in HRV before coronary artery bypass graft (CABG) surgery and during post-operative stay. The secondary aim of this study would be to associate this change in HRV with the patient’s clinical course. The validation component will test WHOOP’s HRV capabilities compared to the gold-standard Holter monitor. 

This is a Prospective, multi‐center, international, randomized controlled, post‐market trial.

Obesity is a chronic, debilitating, multi-factorial disease that has reached worldwide pandemic proportions. The prevalence of obesity has tripled since the 1980s in many countries of the World Health Organization (WHO) European region. The WHO estimates that by 2015, 2.3 billion people will be overweight and over 700 million will be obese.

This is a Phase 3, randomized, double-blind, placebo-controlled study to evaluate sotatercept when added to background PAH therapy in newly diagnosed intermediate- and high-risk PAH patients.

The purpose of this randomized study is to evaluate the safety and effectiveness of EVAHEART 2 Implantable Left Ventricular Assist System (EVA2 LVAS) by demonstrating non-inferiority to HeartMate 3 when used for the treatment of advanced, refractory, New York Heart Association Class IV heart failure.

This is a Phase 2 study investigating safety and tolerability of Inhaled Treprostinil in participants with Pulmonary Hypertension associated with Interstitial Lung Disease.

Collecting and storing heart tissue and blood samples from consented Tufts Medical Center patients for the purpose of cardiovascular research.

This study explores changes in heart function before and after activation of Impella or ECMO devices used to support subjects in cardiogenic shock. 

This research is being done to study a potential method of improving blood flow and oxygen delivery to the organs of patients on VA-ECMO. This study involves positioning the return cannula in the aorta, which is the main artery that carries blood away from the heart. We aim to prove that returning oxygenated blood to the aorta is safe and feasible. We also aim to better understand the effects that this method may have on the forces that affect blood flow and heart function.

Aortic stenosis (AS) affects over 12.6 million adults and causes an estimated 102,700 deaths annually. There is interest in novel approaches to identify valve disease earlier the disease course before symptoms occur. We previously used machine learning (ML) to develop a system for fully automated AS screening. Here we are validating the performance of this new method for identifying AS.

This is a pilot, multinational, multicenter, randomized, double-blind, placebo-controlled, 2-part safety and efficacy study. Subjects will consist of males or females 18 to 85 years of age, hospitalized for acute decompensated heart failure (ADHF) with persistent hypotension (systolic blood pressure [SBP] 70-100 mmHg for two hours) and heart rate 75 to 150 beats/minute.

This study is designed to evaluate the safety and efficacy of sotatercept versus placebo in adults with Cpc-PH due to HFpEF. 

While much has been learned about the acute phase of Coronavirus disease 2019 (COVID-19) in the last year, little is known about the recovery phase. There have recently been several reports in the news and in the medical literature about a prolonged recovery phase after developing acute COVID-19 in some individuals who may have persistent symptoms many months after infection, developing the so called “long COVID”.

This is a Prospective, multicenter, randomized, parallel-controlled, open-label two arm trial with an adaptive design. Eligible subjects will be randomized in a 1:1 ratio to PCI with Impella CP® (Intervention Group) versus standard of care PCI with or without IABP (Control Group). Approximately 1252 subjects will be randomized in a 1:1 ratio to PCI + Impella vs. PCI ± IABP.

Rheumatoid arthritis (RA) is a chronic, slowly progressive condition for which numerous treatment options are available. The therapies vary in mechanism of action, mode of administration, side- effect (adverse event) profile, and cost. While consensus treatment guidelines are available, identifying an optimal treatment sequence is often based on clinician choice with treatment changes based on tolerability and short- term outcome. The N-of-1 trial will evaluate individual participant and aggregate data. Individual participants will be enrolled and randomized to a sequence of three U.S.

The MADIT S-ICD trial is 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 primary objective for this early feasibility study is to assess safety and feasibility of the Impella ECP device in adult patients undergoing an elective high-risk percutaneous coronary intervention. To assess safety, special attention is being paid to the effect of the pump on the aortic valve

This is an observational study to assess the the burden of neuropathic involvement in wild-type transthyretin amyloidosis
