The TEAM-HF trial aims to find out whether measuring pressure in the heart and lungs using an implantable device called a CardioMEMS can help identify heart failure patients who are getting worse and may benefit from earlier treatment with a heart pump called an LVAD. It also seeks to determine if patients with advanced heart failure, who are not on IV medications for their heart failure but still have high pressures in their heart and lungs can improve with LVAD therapy.

The objective of the study is to evaluate the safety and efficacy of the BrioVAD System by demonstrating non-inferiority to the HeartMate 3™ (HM3) LVAS (Abbott) when used for the treatment of advanced, refractory, left ventricular heart failure.

This study is enrolling participants who completed the FARAPULSE ADVENT study and are now nearing the 3 year post atrial fibrillation ablation timepoint. Atrial fibrillation is an irregular heart rhythm caused by electrical signals misfiring. An ablation is a procedure in which those signals are targeted and destroyed to stop the atrial fibrillation. This study will consist of reviewing and collecting medical records since the ablation procedure as well as optional questionnaires and wearing a heart monitor for 7 days to capture the heart's electrical activity. There are no study related follow up visits. Study related risks include loss of confidentiality and possible skin reaction to the electrodes (sticky patches placed on the chest to detect the heart's electrical activity). Individual benefit is not expected but the information learned may contribute to knowledge in this field.

This study is enrolling subjects with tricuspid regurgitation, which is what occurs when the tricuspid heart valve on the right side of the heart does not close properly and blood leaks backwards. Over time this can lead to symptoms like shortness of breath and fluid build up in the legs, abdomen, and lungs. This study involves a new investigational device called the TricValve® Transcatheter Bicaval Valve system to treat the leaky valve. Investigational means it is not approved for commercial use by the Food and Drug Administration. (FDA) This study will last about 5 years and include about 11 visits. Study related procedures include physical exams, right heart catheterization (an invasive procedure to check pressures inside the heart), echocardiograms (ultrasound test of the heart), CT scan, blood work, questionnaires, hall walk test and procedure to place the device. Risks include those related to the device and procedure such as infection, failure of the device, worsening of your symptoms or other cardiac complications. There are also risks associated with study testing such as radiation risks, blood draw risks, loss of confidentiality and unknown risks. There is potential benefit to you and to others in the future from what is learned from this study.

The purpose of this study is to find out if the investigational drug/study medicine (omecamtiv mecarbil) can reduce the risk of the effects of heart failure (HF), hospitalization, transplantation, or death. It is hoped that the study medicine increases the heart's ability to pump blood throughout the body, but we need to learn more about its effect in patients who suffer the most from HF symptoms. "Investigational" means that the study medicine is still being tested in research studies and has not been approved by the U.S. Food and Drug Administration (FDA). The study drug will be taken by mouth twice daily.

Participation in this study will last for approximately 3 years, however, participation could last from a few weeks to a few years depending on your time of enrollment. These visits will include physical exams, blood draws, electrocardiograms (ECG), echocardiogram (Echo), blood draws, questionnaires along with receiving the study drug. Participants will receive the study drug and have a 2 week wash out period to ensure tolerance. From there, participants will be randomized to either the treatment group (and receive the medication) or the control group (and not receive the medication). The treatment assignment is determined by randomization, where a computer selects at random which treatment group you will be in (like drawing straws). Neither the subject, nor the blinded study personnel will know which group subjects are in. Neither the subject nor the study doctor or study staff will decide what group subjects are assigned.

This study is studying the investigational medication EDG-7500 for the treatment of obstructive and non obstructive hypertrophic cardiomyoapthy. Investigational means it is not approved for sale by the Food and Drug Administration (FDA) The study will test to see if the medication can help the heart expand and fill to help its workload. The study has 4 Parts, each of varying durations. The study will last a minimum of 6 weeks to a maximum of 18 months. Study related procedures include physical exam, electrocardiogram (ECG) - a tracing of the heart's electrical activity, echocardiogram (echo) - ultrasound test of the heart, blood and urine collection, possible genetic testing, and exercise testing. Risks related to the study medication include atrial fibrillation (fast irregular heartbeat), constipation, diarrhea, dizziness/lightheadedness and upper respiratory infection. Other study related risks include loss of confidentiality, unknown risks and risks related to procedures.

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.

Atrial fibrillation (AF) is an arrhythmia in which the heartbeat becomes irregular due to abnormal electrical signals in the upper chambers of the heart, called the atria. This leads to ineffective pumping of blood by the atria. Complications related to atrial fibrillation are heart failure, stroke, heart palpitations and fatigue. This study is motivated by the need to address the increasing prevalence of AF, which is the most common sustained arrhythmia worldwide. While treatment options for AF include the use of antiarrhythmic drugs which are a group of medications used to treat irregular heartbeats, and catheter ablation procedures, the latter have been associated with significantly better outcomes. Participation in this study consists of 2 phases, 1- randomization 2- ablation procedure and follow-up period.
The randomization to the different groups is considered the research part of the study. Subjects will have equal chance of being randomized (like tossing a coin) to one of two AF ablation treatment groups. All follow up will be according to stand of care practices. Risks include stroke, pericarditis, acute and delayed perforation, hemolysis, acute kidney injury, and coronary artery spasm.

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 enrolling subjects with coronary artery disease (blockages in the arteries that supply blood to the heart) who need to undergo a procedure called a Percutaneous Coronary Intervention (PCI) to open up a blocked heart artery. At times, a heart pump is used during a PCI to help reduce the work the heart during the procedure. This study is evaluating a heart pump called the KARDION CORY P4 pump. The KARDION CORY P4 pump is investigational meaning it has not been approved for commercial use by the Food and Drug Administration (FDA). This study will randomize subjects, meaning assign by chance, to receive either the KARDION CORY P4 pump or the Impella CP, which is commercially available.

Study participation will last about 30 days and include up to 6 visits. The study includes blood work, questionnaires, an electrocardiogram (ECG) - a tracing of the heart's electrical activity and an echocardiogram (Echo) - an ultrasound test of the heart.

Risks include risks related to the study device including bleeding, infection, and injury to the blood vessel where the device is placed. There are also risks related to study procedures. There may be benefit and the information learned may benefit others in the future.
