This study is enrolling subjects with heart failure and a reduced ejection fraction meaning the heart does not pump enough blood to meet the body's needs. This study is researching an investigational device (study device) called the Alleviant ALV1 System. Investigational means it has not been approved for commercial use by the Food and Drug Administration. (FDA) This study will test the safety and effectiveness of the Alleviant ALV1 System. The Alleviant ALV1 System is intended to create a shunt (an opening) in the heart to allow for proper blood flow through the heart which may improve your symptoms. No device is left in your heart it is just used to create the shunt. This is a randomized study which means subjects are assigned by chance to either have the study device create this shunt or not have the study device create the shunt. Randomization is 50/50 meaning there is a 50% chance to have the study device create a shunt and a 50% chance the study device will not be used. Using the study device to create the shunt is performed during a right heart catheterization (RHC) so all subjects will undergo the RHC but only 50% will have the shunt. Neither the subjects nor the study doctor will know which group subjects are randomized to but other study staff will know in the event this information is needed. All subjects will stay overnight in the hospital after the procedure. Other study related procedures include echocardiograms - ultrasound test of the heart, electrocardiograms (ECG) - a tracing of the heart's electrical activity, blood work, questionnaires, 6 minute hall walk test, and assessments of heart failure status. Risks include risks related to the study device including blood vessel damage from placing the device in the vein to get to the heart, risks from the right heart catheterization such as bleeding or bruising, abnormal heart beats, and risks related to study related procedures. There may be risks that are not known at this time. Participation in this study is expected to last about 60 months and include approximately 15 in person visits and 3 telephone calls.

This study is an open label, Comparative Effectiveness Research study in patients who receive a heart transplant. Subjects will be enrolled into the study while under evaluation for heart transplantation or on the transplant waiting list prior to heart transplantation. All subjects will follow the center's standard of care surveillance schedule from transplant through 4 weeks post-transplantation. The study objective is to compare the effectiveness of rejection surveillance of heart transplant recipients with Prospera dd-cfDNA to rejection surveillance with endomyocardial biopsy (EMB) in the first post-transplant year.
The Prospera™ test is a non-invasive test intended to detect and quantify the fraction of donor-derived cell-free DNA (dd-cfDNA) to supplement management and surveillance of allograft rejection in patients who have undergone organ transplantation. The subjects may undergo blood draws, echocardiogrphys, medical history and physical exams, antibody testing, nuclear imaging, and MRI as apart of the study. The study period will be during the first 12 months post-transplant. Quality of life questionnaires will be completed at week 4, month 6 and month 12 post-transplant.

This study is asking for volunteers who have been diagnosed with acute pulmonary embolism (PE). PE is a blood clot that blocks and stops blood flow to an artery in the lung. PE usually results from a blood clot in the leg that travels to the lung. Patients with PE may have shortness of breath, chest pain and/or an irregular heartbeat. This study will use a device known as the Vertex Pulmonary Embolectomy System. The Vertex Pulmonary Embolectomy System is a medical device which is indicated for use in the pulmonary arteries for the non-surgical removal of blood clots from blood vessels. The Vertex System has not yet been approved for use by the Food and Drug Administration (FDA) but is approved for use in this study for PE removal. Your study doctor will inform you about the risks that are related to your PE procedure. The risks associated with the study include loss of confidentiality and unknown risks. There will be no benefit to you, but it is hoped the information gained will add to the understanding of treatment options for others in the future. You do not have to participate to have your condition treated. This study will take 30 days to complete.

This clinical research study is enrolling adults with diabetes, prediabetes or metabolic syndrome. The purpose of the study is to learn more about preventing cardiovascular disease. A heart CT scan will be done at screening and then 2 years later. Qualified participants will be randomly assigned to one of two groups. Participants in the usual care group, will continue to receive care from usual health care provider. In the personalized care group, participants will receive additional health care from a remote cardiologist led team which will individualize treatment based on Cleerly CAD staging results of the heart CT scan. Study is expected to last 3 1/2 years on average but could be 2 - 5 years. Participation is free.

The purpose of this study is to determine if patients with heart failure (HF, meaning a weak heart) with left ventricular ejection fraction (LVEF) ≤ 50% and with an abnormal heart beat can benefit from having pacemaker leads placed in a different location in the heart. We know that people with a weak heart and an abnormal heart beat can benefit from having a pacemaker. Participants in this study will be randomly assigned (like flipping a coin) to one of two treatments (A or B), both of which are standard of care heart pacing treatments:
A. Pacing the heart from two locations in the left ventricle (lower left chamber of the heart)
B. Pacing the heart from one of two other places in the heart (the "His" or the left bundle branch)

The purpose of this study is to compare side by side these two treatments and evaluate if one is better than the other.

The purpose of this research is to gather information about the effectiveness and safety of Left Atrial Appendage Occlusion (LAAO) device procedures in patients using a Watchman device performed on days where doctors perform a large number of procedures.

The study primary outcome is to evaluate complications during the procedure up to 30 days after the procedure.

The final outcome is to determine successful placement within 31 - 90 days after implant.

We are doing this study to learn more about how effective, safe and tolerable an experimental drug called balcinrenone is when used in combination with dapagliflozin for treating patients with heart failure and impaired kidney function and also to better understand the studied disease and associated health problems. Dapagliflozin is an approved drug to treat patients with heart failure, chronic kidney disease and type 2 diabetes mellitus.

The purpose of the study is to determine whether FINErenone reduces total (first and future) Heart Failure events and cardiovascular death compared with placebo in patients hospitalized with acute decompensated Heart Failure with Mid-Range Ejection Fraction and Heart Failure with Preserved Ejection Fraction (HFmrEF/HFpEF. The study will also look at information obtained from the tests performed as part of the study to see if subjects have improvement in symptoms of heart failure. Participation in this study will last approximately 36 months. During the study period subjects will be asked to attend regular study visits with the research coordinator. These visits will include such activities such as vitals, blood tests and questionnaires. There will be 8 visits as part of participation in this clinical trial. Participants will be randomized to either the treatment group (and receive the medication) or the control group (and not receive the medication). Subjects will have a 50:50 chance of receiving the study medication during their participation in the trial. The treatment assignment is determined by randomization, where a computer selects at random which treatment group you will be in (like flipping a coin). Neither the subject, nor the blinded personnel will know which group subjects are in. Neither the subject nor the study doctor will decide what group subjects are assigned.

You are invited to volunteer in this clinical research study because you have been diagnosed with tricuspid valve regurgitation.

The type of research study you are being asked to join is called an Early Feasibility Study. This means the device and procedure you are receiving (the treatment) have not been previously studied in humans, and that you will be among the first patients in the world to undergo this treatment. The Device you are receiving is not approved by the United States Food and Drug Administration and its safety and effectiveness are unknown.

Participants will undergo right heart catheterizations, computed tomography (CT) scans without iodinated contrast, multiple ultrasounds of the heart, labs, and other assessments. The length of subject participation in the study is 5 years and includes 11 research visits. You will have a screening right heart catheterization (RHC) to check the pressures and function of your heart. The research procedure and placement of the TRIcares Topaz Transfemoral Tricuspid heart Valve (Topaz Tricuspid Valve) will be placed in a hybrid operating room. This procedure is done by entering a vein in your groin known as the femoral vein. The purpose of this device is to eliminate the regurgitation or leaking in the tricuspid valve of the heart to help reduce the symptoms caused by this leaky valve.

The most common risks associated with the research procedure are those related to the right heart catheterization (RHC) and Topaz Tricuspid valve procedure. Major risks include bleeding and damage to the heart or surrounding blood vessels. There are no known benefits of the research device. There may be possible benefits from the research procedure including improvement in quality of life or a decrease in the symptoms caused by tricuspid regurgitation. The information that we obtain from your participation in this study will help us learn more about how safe and effective this approach is in treating the symptoms of individuals similar to yourself.

This study involves an investigational drug called ALXN2220 for the treatment of transthyretin amyloid cardiomyopathy (ATTR-CM). Investigational means it is not yet approved for commercial use or sale by the Food and Drug Administration (FDA). ALXN2220 is intended to promote the elimination of ATTR deposits leading to symptom improvement.
All participants will be randomized, meaning assigned by chance, to receive ALXN2220 or placebo. A placebo looks like the study drug but contains no active medication. In this study, participants will have a 2 out of 3 chance, like drawing straws, of receiving the study drug and 1 out of 3 chance of receiving placebo. Neither the participants nor the study team or study doctor will know if they are assigned to receive the study drug or placebo. The study drug or placebo will be administered intravenously (IV), meaning into a vein in the arm, every four weeks.
Participation in this study will include a maximum of 56 visits over a maximum of 48 months. Study procedures include collection of vital signs, study drug infusion, physical exams, 12-lead electrocardiography, blood and urine collection, echocardiogram (ultrasound test of the heart), questionnaires, and some optional testing.
