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.

This study is enrolling subjects with high blood pressure who just received a pacemaker (an implantable device placed in the upper chest that monitors the heart rate and can send an electrical signal if needed to pace the heart to maintain a normal heart rate) or are about to undergo a pacemaker implant. This is a randomized study meaning subjects will be assigned by chance to have a new program downloaded to the pacemaker to help control blood pressure or to not receive the program. Subjects will have a 50:50 chance to receive the program. The new program is called AVIM therapy and it is investigational meaning it has not been approved by the US Food and Drug Administration. (FDA) Participation in this study will last about 36 months and include about 10 visits. Study related procedures include blood pressure monitoring including wearing a 24 hour blood pressure monitor, blood work, questionnaires, echocardiogram - an ultrasound test of the heart, pacemaker interrogation (meaning your pacemaker is checked to obtain the information stored on it) and randomization. Study related risks include risks related to the software download such as the risk that the software will not help control blood pressure, risks related to study related procedures and the risk of the loss of confidentiality.

This study is testing a new radiotracer dye called I-124 evuzamitide in patients with suspected cardiac amyloidosis. Cardiac amyloidosis occurs when proteins misfold and deposit as amyloid fibrils in the heart. The build up of these fibrils (proteins) cause the heart to enlarge due to wall thickening so the heart has to work harder. Over time, this can lead to heart failure. I-124 evuzamitide is given during a Positron Emissions Tomography/ Computed Tomography (PET/CT) scan to help diagnose cardiac amyloidosis. It is not a treatment for amyloidosis. I-124 evuzamitide is considered investigational meaning it is not approved for commercial use by the Food and Drug Administration. (FDA). It will be given one time through an intravenous line, meaning in the vein before the PET/CT scan.

This study will last about 60 days and include 4 visits. The final study visit will take place at day 30 but medical records will be reviewed up to day 60. In addition to receiving I-124 evuzamitide, participants will also receive potassium iodide, an approved medication, by mouth to take for 3 days to protect the thyroid gland from the radiotracer I-124 evuzamitide, electrocardiogram (ECG), bloodwork and questionnaires.

This study is enrolling subjects who are undergoing an atrial fibrillation ablation. Atrial fibrillation (AF) is a condition where the heart beats rapidly and irregularly. An ablation procedure can destroy the tissue in the heart that transmits the irregular electrical signals that cause the AF. The ablation procedure will use the PulseSelect™ PFA System which is approved by the Food and Drug Administration (FDA) and uses electroporation (electrical pulses) to destroy the heart tissue.

This study will last about 2 years and include up to 6 visits, some of which can be done virtually. Study procedures include data collection, questionnaires, electrocardiogram (ECG) - which is a tracing of the heart's electrical activity, echocardiogram (Echo) - which is an ultrasound test of the heart, and a Holter monitor - which is a wearable device that continuously records heart rhythm.

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.

This study involves a procedure called renal denervation with an investigational device called the TIVUS™ system for the treatment of resistant hypertension (high blood pressure). Investigational means it is not yet approved for commercial use by the Food and Drug Administration (FDA). Renal denervation is a procedure done by introducing a catheter (long tube) into the large blood vessel in your groin (top of leg) and guiding it to your renal arteries, which are the blood vessels that go to your kidneys. The catheter will be placed in the renal arteries and ultrasound energy will be delivered to the renal arteries.
This study is randomized, meaning you will be assigned to one of two groups, by chance, like drawing straws. Two out of three participants will be randomized to renal denervation while one out of three will be randomized to sham. Sham means you will go through all the steps of the procedure but will not receive the treatment. Those participants randomized to sham will have the option to crossover and have the procedure after the 6 month follow up.
This study will involve at least 12 visits over the course of 36 months. Study related procedures include CT scan, ultrasound test of your heart and kidneys, blood work, urine studies, physical exams, questionnaire, and keeping home blood pressure diaries.
Study related risks include risks related to the procedure including pain, bleeding, damage to the blood vessels, risks related to the study related testing such as radiation risks, blood draw risks and loss of confidentiality. There may be benefit to you as well as others in the future with high blood pressure.

This study is enrolling participants with heart disease or at high risk of developing heart disease who are already taking a cholesterol lowering medication referred to as a statin. This study is specifically seeking participants who are historically underrepresented in cardiovascular clinical trials including females, and racial/ethnic minorities, as well as those living in rural areas. This study involves the medication inclisiran which is an approved medication to help lower "bad" cholesterol. In this study participants will be randomized meaning assigned by chance to receive inclisiran along with usual care or not receive inclisiran and will continue usual care for the first 360 days. You will have a 50:50 chance, like flipping a coin, to receive inclisiran. Those participants who are randomized to not receive inclisiran initially will then receive it after day 360 and continue in the study for another 360 days so up to day 720. Participation will take up to 7 study visits.

Study related procedures include collecting medical history, demographics, questionnaires and blood work, as well as receive inclisiran as a shot just under the skin every 4 months. Study related risks include injection site reactions, joint pain or stiffness, bronchitis or an allergic reaction. There is also a risk of loss of confidentiality.

This study involves collecting data and physician feedback while using the ViewFlex X System during a routine electrophysiology (EP) procedure. An electrophysiology procedure is done to correct an electrical abnormality in the heart. The ViewFlex X System is considered investigational meaning it has not been approved for commercial use by the Food and Drug Administration (FDA). The ViewFlex System will obtain and integrate heart images with the mapping information obtained during your procedure. There is also an option to have the procedure videotaped. Study participation lasts until hospital discharge post procedure. Study related risks include risks associated with using the ViewFlex X System, loss of confidentiality and unknown risks.
