103 Clinical Trials for Various Conditions
The left ventricular assist device (LVAD) is growing rapidly among people dying from end-stage heart failure who are unable to get a heart transplant. These patients elect to live out the remainder of their lives dependent on a partial artificial heart-so-called destination therapy (DT). Although patients may live longer with a DT LVAD, it poses many risks, including stroke, serious infection, and bleeding. Most of these patients have other medical problems that are not fixed by the DT LVAD. Patients must be connected to electricity at all times. A caregiver is required, which often places stress on loved ones. Therefore, the decision whether or not to get a DT LVAD is often an extremely difficult one. Unfortunately, our research shows problems with the way this medical decision is currently being made in hospitals across the United States. Hospitals that offer DT LVAD treatment do not follow a standard process. The forms, pamphlets, websites, and videos used to help patients and families are biased and too difficult for most people to understand. Lastly, this is an emotional and even scary decision for most patients and their families, but the process does not help them deal with these feelings. Using feedback from patients, caregivers, clinicians, the study team made a paper and video decision aid to help people who are offered DT LVAD make this most difficult of decisions. Unlike the information that is now available, our decision aid focuses on options, fears, and the needs of caregivers, is balanced, and is paired with training for doctors and nurses on how to best talk about DT LVAD. The investigators now propose to test the effectiveness and implementation of this intervention. The investigators will apply the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) evaluative framework to a stepped-wedge, cluster-randomized, controlled trial across 6 medical centers. Aim 1. Evaluate the Reach and Effectiveness of the DT LVAD shared decision support intervention to improve patient and caregiver experiences. Hypothesis 1a: The intervention will reach 90% of eligible patients. Hypothesis 1b: Post-implementation, patients and caregivers will have improved decision quality (greater knowledge and higher value-treatment concordance). Aim 2. Assess the Adoption, Implementation, and Maintenance of the DT LVAD shared decision support intervention across multiple providers and settings. Hypothesis 2: The intervention will be: adopted by key personnel; implemented consistently; and maintained after trial completion.
Sunshine Heart is sponsoring a prospective, multi-center, randomized trial to assess the safety and efficacy of the C-Pulse® System ("C-Pulse"). The purpose of the study is to determine whether the use of the C-Pulse as a treatment for patients in moderate to severe heart failure (HF) has demonstrated safety and efficacy, such that the C-Pulse System merits Food and Drug Administration (FDA) approval to market the device in the United States.
The purpose of this study is to test a home-based exergaming intervention designed to decrease frailty and fatigue and improve affective well-being, functional capacity, and immune function in individuals with advanced heart failure (HF) and multiple chronic conditions (MCC) prior to receiving either a left ventricular assist device (LVAD) or orthotopic heart transplantation (OHT). Prior to surgery, individuals with advanced HF/MCC experience a high symptom burden that often precludes them from participating in meaningful physical activity. Pre-surgical fitness programs have been used in other critically ill populations to improve function prior to surgery. Interactive gaming systems have been successfully used to engage other seriously ill adults in low-intensity physical activity. However, exergaming interventions have not yet been applied in individuals with advanced HF/MCC as prehabilitation prior to LVAD implantation or OHT. The investigators propose that a prehabilitation exergaming intervention will not only enhance pre-surgical outcomes but will also augment postoperative outcomes. This study is designed in two-phases. Phase 1 examines intervention feasibility and phase 2 is a pilot study with a two-group design. In phase 2, participants will be randomized to a usual care group or the exergaming intervention group. The exergaming group will participate in a low-intensity exergaming intervention and additional investigator-developed educational modules that will be delivered via the Nintendo Wii U exergaming system. The investigators will evaluate pre- and post-surgical frailty, fatigue, affective well-being, and immune function as primary outcomes. The investigators expect that participation in low intensity exergaming will improve these primary outcomes pre- and post-surgically, and decrease post-surgical complications and health care utilization. Investigator-developed modules will promote self-efficacy, self-regulation, and activation. This is the first study to apply low-intensity exergaming to a pre-operative advanced HF/MCC population. The successful application of this intervention has significant implications to the pre-operative conditioning of individuals with advanced HF/MCC prior to LVAD implantation or OHT.
This study will collect retrospective and prospective clinical data regarding the Principal Investigator's patient population to allow for data analysis seeking basic trends and to prepare academic reports, including journal manuscripts and presentations for scientific organizations.
The purpose of this observational registry is to determine the freedom from driveline (DL) infection events in subjects implanted with a HeartMate II LVAD in whom only the silicone portion of the DL is externalized resulting in a silicone skin interface (SSI)
This research study will compare two standard of care approaches for managing low sodium levels in heart failure patients with Left Ventricular Assist Device (LVAD). The study will compare the outcomes of LVAD patients with low sodium levels who take Tolvaptan to those who do not take Tolvaptan. Tolvaptan is FDA approved for use in the study population and is commonly used to treat low sodium levels in heart failure and LVAD patients. It is not known if taking Tolvaptan or not taking Tolvaptan is better at improving outcomes in newly implanted LVAD patients with low sodium levels. By doing this study, the Principal Investigator (PI) hopes to learn which is better at improving outcomes.
To evaluate the safety of retrograde coronary sinus infusion (RCSI) of a novel triple-effector plasmid (INXN-4001) in outpatient LVAD recipients as assessed by incidence of all study intervention-related adverse events occurring up to 6 months post-RCSI (primary endpoints), and to evaluate general safety by assessing incidence of cardiac specific adverse events and the incidence of related serious adverse events at intervals up to 12 months post-infusion (or until cardiac transplantation or death).
The goal of this study is to evaluate the safety and efficacy of the BrioVAD System by demonstrating non-inferiority to the HeartMate 3 Left Ventricular Assist System when used for the treatment of advanced, refractory, left ventricular heart failure.
The purpose of this study is to evaluate the use of VAD Care App in an out-patient mechanical circulatory support program. The specific aim for this pilot study is to obtain preliminary efficacy data of the VAD Care App as a self-management tool for patients with long-term LVADs. A randomized control trial will be employed to establish preliminary estimates of the effects of the App on the following outcomes: self-efficacy and adherence to the LVAD care regimen; LVAD-related complications and health care utilization \[e.g., hospital re-admission\]; overall health status and quality of life. The duration of the study is 6 months.
The objective of the study is to continue to evaluate safety and clinical performance of the HM3 LVAS for the treatment of advanced, refractory, left ventricular heart failure following completion of enrollment in the the MOMENTUM 3 IDE Study.
The objective of the study is to evaluate the safety and effectiveness of the HM3 LVAS by demonstrating non-inferiority to the HMII LVAS (HMII) when used for the treatment of advanced, refractory, left ventricular heart failure.
The purpose of the study is to evaluate the safety and effectiveness of the ReliantHeart HeartAssist 5® VAD System in patients listed for heart transplantation and at risk of death from refractory end-stage heart failure.
The purpose of this study is to assess how often blood clots form in the FDA-approved HeartMate® II (HM II) Left Ventricular Assist Device (LVAD) and to identify risks related to clotting within the pump.
We propose to study a strategy empirically applied for the past 6 months at a high volume LVAD center (Vanderbilt Heart and Vascular Institute). This utilizes an ultra conservative device programming strategy to maximize battery longevity, avoid inappropriate implantable cardioverter defibrillator (ICD) therapy, improve quality of life through reduction in overall shock burden, and potentially avoid unnecessary device generator changes prior to transplant. Avoiding CIED (cardiac implantable electronic device) change out device procedures prior to transplant is desirable.
The purpose of this study is to determine the proportion of subjects who have sufficient improvement in ventricular function after undergoing a standardized Left Ventricular Assist Device (LVAD) plus pharmacologic recovery treatment and testing protocol to allow removal of the LVAD within 18 months.
Research study evaluating the individual and combined effects of inhaled nitric oxide (iNO) and inhaled prostacyclin (iPGI2), on the function of the right heart after surgery for either heart transplant or for left ventricular assist device (LVAD) placement. The investigators hope to learn if these two medications, when given together after surgery, improve right heart function by lowering blood vessel pressures in the lungs. The investigators hope to learn if the combined effects of these two medications are better than either medication used alone. Participants were selected as a possible participant in this study because right heart problems are common during and after surgery for heart transplant and for LVAD placement. In addition, iNO is always given during and after these two types of surgeries at Stanford to help improve how the right heart functions.
The purpose of this study is to evaluate the feasibility of a Percutaneous Lead Management Kit for HeartMate II driveline stabilization and exit site management.
The purpose of this study is to evaluate and compare the effectiveness of the HeartMate II (HM II) Left Ventricular Assist Device (LVAD) support versus OMM in ambulatory NYHA Class IIIB/IV heart failure patients who are not dependent on intravenous inotropic support and who meet the FDA approved indications for HM II LVAD destination therapy.
To observe and document ventilation parameters in the advanced heart failure population, through the course of illness, which often includes cardiac resynchronization therapy (CRT), left ventricular assist device (LVAD), and transplant. Findings from this cohort are anticipated to be of sufficient interest to the scientific community to merit publication and are likely to provide preliminary data for future hypothesis generation and subsequent prospective, randomized controlled trials. A compact, inexpensive apparatus has recently become commercially available for performing sub-maximal exercise testing (SHAPE Medical, St Paul, MN), including gas exchange analysis and will be used in this study. This apparatus is not investigational.
The purpose of this study is to evaluate whether patients with chronic heart failure not due to coronary artery disease who require use of a left ventricular assist device (LVAD) for refractory heart failure can recover sufficient heart function to allow the pump to be explanted. The study aims to avoid the need for transplantation in these patients by using standard heart failure medications to reduce the size of the left ventricle and then using the investigational drug, clenbuterol, to further improve left ventricular function.
The purpose of this study is to determine the safety and effectiveness of the Thoratec HeartMate II Left Ventricular Assist System (LVAS) as Destination Therapy in end-stage heart failure patients who do not qualify for cardiac transplantation. The Destination Therapy indication for use was approved by FDA on January 20, 2010 (ref. PMA P060040/S005).
The purpose of this study is to determine the safety and effectiveness of the Thoratec HeartMate II Left Ventricular Assist System (LVAS) as a bridge to cardiac transplantation in end-stage heart failure patients who are listed for cardiac transplant but are at imminent risk of dying. The HeartMate II LVAS was approved by the US FDA on April 21, 2008, as a bridge to cardiac transplantation (reference PMA P060040). It was approved for commercial distribution in Canada on May 20, 2009 (reference Medical Device Licence #79765). Patients enrolled into the clinical trial will continue to be followed until all have reached a clinical outcome.
Left Ventricular Assist Devices (LVAD) are mechanical heart pumps that are increasingly being implanted in patients with severe heart failure which have failed medical therapy. In patients with LVADs, right ventricular failure, which is not supported by the LVAD pump, is a major problem that affects quality-of-life and survival. Cardiac Resynchronization Therapy (CRT) aims to restore the synchronized contraction of the heart and has proven to be beneficial for improving ejection fraction of both right and left ventricle as well as quality of life in selected heart failure patients. The role of CRT in patients with LVADs is unknown. We hypothesize that CRT can exert a beneficial impact on right ventricular function in LVAD patients and improve their quality-of-life. The specific questions that this study aims to answer are: 1. What are the effects of CRT on the function of the non-supported right ventricle in patients with an implanted LVAD? 2. Can the effects of CRT on cardiac function positively impact quality-of-life and exercise capacity in LVAD recipients? In this study patients with a previously implanted CRT device, who later receives an LVAD, will be randomly assigned to have the CRT turned off (CRT-off) or on (CRT-on). The patients will be followed for an 8-week period, and then switched over to the opposite CRT status. The total participation in this study will last for 16 ± 1 weeks, and will involve 3 clinic visits of approximately 3 hour duration (initial visit, 8 week visit, and 16 week final visit), plus 2 quick checks of the pacemaker/defibrillator in-between the visits. Heart function will be assessed with comprehensive echocardiographic studies during the CRT "on" and CRT "off" periods. Quality-of-life and exercise capacity will be assessed with a standardized questionnaire and a 6-Minute Walk Test.
Heart failure is a world epidemic. LVADs are increasingly used as they have demonstrated improved survival rates compared to optimal medical management. Improving outcomes have been seen with the newer LVAD technology, the HeartMate 3 (Abbott, Chicago, IL), however, hemocompatibility related adverse events, including thrombosis and bleeding, are still a major cause of morbidity and mortality. The recent ARIES trial showed that in patients with advanced heart failure treated with a HeartMate3 LVAD, avoidance of aspirin as part of an antithrombotic regimen, which includes vitamin K antagonist (VKA), is not inferior to a regimen containing aspirin, does not increase thromboembolism risk, and is associated with a reduction in bleeding events. This clinical investigation is a prospective, randomized, controlled study of advanced heart failure patients supports with the HeartMate3 for more then 3 months with two different antithrombotic regimens: VKA with and without aspirin. The objective of this investigation is to study the safety and efficacy of an antithrombotic regimen without antiplatelet therapy.
The purpose of this study is to determine if the delivery of cells just after implantation of left ventricular assist device will help to improve the pumping function of your heart and minimize heart enlargement in the future. The cells will be obtained by aspiration or withdrawal of fluid from your bone marrow from your pelvic bone using a needle and syringe. This would not take place until 24-48 hours prior to your planned left ventricular assist device implantation. During the surgery the surgeons will inject the prepared cells that were taken from your bone marrow and inject it into your heart muscle. This study will test whether receiving your own bone marrow cells directly into your heart will help your heart to recover function after placement of a left ventricular assist device.
The purpose of this clinical trial is to see if a new device (SCD) is safe and if it can reduce damage to the kidney enough to allow medications to work to improve heart and kidney function for use in patients that have moderate to severe heart failure and is at least in part due to heart failure and it not responding to standard medical therapy. The SCD is a cartridge used with a commercial hemodialysis unit. Participants will be enrolled in the clinical trial once eligibility is confirmed. In addition to clinical assessments and laboratory testing participants will have surface echocardiograms during the trial. The SCD treatment will take place for 4 hours on day 1, 3, and 5 while on hemodialysis.
This is an observational study evaluating changes in frailty and associated impairments in older heart failure patients receiving left ventricular assist device therapy.
Certain patients with congestive heart failure are treated both by implantation of an LVAD, as well as implantation with a biventricular pacemaker. Both of these devices, individually, have been shown to improve the health of patients with heart failure. However, only a small number of patients have both an LVAD and a biventricular pacemaker at the same time. Pacemakers have many different settings. However, there is little data to inform physicians which of these different settings is best for the flow of an LVAD. This study is evaluating patients who have both a biventricular pacemaker and an LVAD. Investigators will operate the pacemaker at multiple different settings and monitor the LVAD's function to determine which, if any, setting is best for the LVAD's flow.
This is a Phase 1b/IIa, single centre, non-randomised open-label uncontrolled study to assess safety, effect and PK of oral CRD-102 in patients with RHF associated with the presence of an LVAD.
Heart failure remains a major cause of morbidity and mortality. Many patients with heart failure receive support from a left ventricular assist device (LVAD) at some point in the course of their disease. Some of these LVAD patients experience a durable recovery after ventricular unloading with an LVAD, which may be associated with inhibition of inflammatory cytokines. This small pilot study aims to determine the biologic and clinical efficacy of an interleukin-1 receptor antagonist (Anakinra) at inducing myocardial recovery in patients supported with left ventricular assist devices.
