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.

This study will evaluate the association between feeding recovery and clinical assessment of infant behaviors as measured in a brief survey to assess irritability, ability to be soothed, alertness, non-nutritive sucking, and muscle tone. Forty infants will be recruited from the PCICU-CSD at MUSC. This data will be assessed using the Neoneur Feeding System to create a model of feeding recovery.

This study is for patients with hypertrophic cardiomyopathy (HCM). HCM is a condition where the heart muscle becomes abnormally thickened, which can sometimes block the blood flow out of the heart and results in the heart muscle working harder to pump blood to the body. Participants who have completed participation in a previous HCM study investigating the study drug, called aficamten (CK-3773274), will be eligible to participate in this study.

The study is done to collect long-term safety and tolerability data, including assessments of cardiac structure and function during chronic dosing with aficamten. Aficamten is a tablet taken by mouth. This is an open label study (the participants and study team will know the dose of aficamten taken at any given time). If your screening results show you are eligible to continue in the study, you will visit the research site for the "first dosing day" (Day 1), followed by visits at Weeks 2, 4, 6, 12, then every 12 weeks thereafter. Study related procedures include blood work, echocardiograms (ultrasound test of the heart), electrocardiogram (recording of heart's electrical activity), physical exams, and questionnaires. Risks associated with this study include shortness of breath, nausea, diarrhea, headaches and dizziness.

This study is enrolling subjects with an abnormal heart rhythm called ventricular tachycardia (VT - rapid heart beat coming from the bottom of the heart) that has come back despite treatment. This is a randomized study meaning subjects will be assigned to one of two groups and then undergo either a standard catheter ablation or a new treatment called cardiac radioablation for their VT. You will have a 50:50 chance of being assigned to either group. A standard catheter ablation is done by placing catheters (long hollow tubes) into a large blood vessel at the top of the leg, guiding them to the heart to first identify the signals causing the VT and then use radiofrequency (heat) energy to burn and stop these signals to stop the VT. The cardiac radioablation is an investigational treatment meaning it is not yet approved for routine clinical use by the Food and Drug Administration (FDA). Cardiac radioablation is performed in the radiation oncology department and uses radiation therapy to treat the signals causing the VT. Participation in this study will last up to 5 years and inlcude about 15 visits. Study related procedures include medical record review and data collection, electrocardiogram (tracing of heart's electrical activity), echocardiogram (ultrasound test of the heart), CT scans, blood work, questionnaires, implantable cardioverter defibrillation (ICD - device implanted in your chest that monitors and treats abnormal heart rhythms), and ablation procedure per randomization. Risks include fatigue, changes in the appearance of the lungs in the cardiac radioablation group, fatigue, pain, low or high blood pressure or excessive bruising or bleeding at the catheter insertion side in the cardiac ablation arm. There are also study procedure related risks, and risks that are not known. There is potential benefit to you and to others in learning how to better treat others in the future with this condition.

This study is for those with Transthyretin (TTR) Amyloidosis with Cardiomyopathy or ATTR-CM. ATTR-CM is a condition where the heart muscle does not pump your blood through your body as it should because of build up of abnormal protein between the muscle fibers in your heart. The specific protein is called transthyretin amyloid (TTR). The study involves an investigational drug called NTLA-2001. Investigational means it is not approved for commercial sale or use by the Food and Drug Administration. This study is a randomized study meaning participants will be assigned by chance to receive NTLA-2001 or placebo. A placebo looks like the investigational drug but contains no active ingredient. In this study, two out of three participants are assigned to receive NTLA-2001 and one out of three will receive placebo. NTLA-2001 or placebo are given by intravenous (IV) infusion meaning in your vein.

NTLA-2001 consists of a gene editing system which can "knockout" the TTR gene and permanently change the DNA (deoxyribonucleic acid, which contains information that determines parts in traits such as eye color or height, that are passed on from parent to child) so the gene stops making the TTR protein.

This study will last at least 18 months and include up to 17 visits. Study related procedures include physical exams, blood work including genetic testing, eye exam, hall walk test, electrocardiograms (ECGs), echocardiogram (echo) and vitamin A supplement. Study risks include infusion related risks like headache, fever, chills, or increased liver enzymes. Other study related risks include genetic risks, loss of confidentiality and unknown risks.

This study is for participants who have tricuspid regurgitation, a condition in which your heart's tricuspid valve does not close tightly which causes blood to flow backwards in the incorrect direction. This condition increases the workload on the heart and if left untreated, it can increase the risk of worsening heart failure. In this study, a device called the VDyne Transcatheter Tricuspid Replacement System will be used to treat the tricuspid regurgitation. The VDyne Transcatheter Tricsupid Replacement System is an investigational device meaning it has not been approved for commercial use by the US Food and Drug Administration (FDA). In this study all eligible participants will be treated with the device.

Participation in this study will last about 5 years and involve up to 13 visits. Study related procedures include a right heart catheterization (test to measure the pressures in the heart), echocardiograms (ultrasound test of heart), electrocardiogram or ECG (test of the heart's electrical system) blood work, questionnaires, hall walk test, and physical exam.

There are risks associated with this study including potential risks with the device, implant procedure and study related procedures. There is also the risk of loss of confidentiality. The study may or may not benefit you but the information learned may benefit others with this condition in the future.

This study is for patients who have heart failure with pulmonary hypertension. Heart failure means that the heart cannot pump blood as well as normal. Pulmonary hypertension happens when the pressure in the blood vessels leading from the heart to the lungs is too high, blood flowing through the lungs is limited, and the pressure in the lungs increases when you are physically active, causing symptoms of shortness of breath and tiredness.

The study uses the Gradient device to see if can help treat heart failure with pulmonary hypertension. This device and therapy is still investigational, which means it is currently not approved by a regulatory agency (such as U.S Food and Drug Administration) for regular hospital use and it includes only individuals who choose to take part. Risks in this study include those for standard cardiac catheterization techniques and the administration of anesthesia including allergic reactions, low blood pressure, skin rash, or difficulty breathing; however, all of the risks may not be known. The study will last approximately 3 years and includes the following visits: Baseline/Screening, Procedure, Discharge, 1 month, 6 months and visits annually for 3 years. Study related procedures include a physical exam, blood testing, 6 minute walk test, echocardiogram, CT scan and a Right heart catheterization.

This study is enrolling subjects with non-obstructive hypertrophic cardiomyopathy (nHCM). nHCM is typically a genetic condition in which the main pumping chamber of the heart (called the left ventricle) becomes abnormally thickened and stiff, which makes it harder for the ventricle to fill and pump out enough blood. This study involves the investigational medication Aficamten, which means it is not approved for commercial use by the Food and Drug Administration. (FDA) Aficamten is designed to reduced excessive heart pumping function. This is a randomized study which means all subjects are assigned to receive either Aficamten or placebo. Subjects have a 50:50 chance of being assigned to either group, but will not know which group they are assigned. Placebo looks like the medication but does not have any active ingredients in it. Study procedures include exercise testing, echocardiograms (ultrasound test of the heart), blood work, questionnaires and genetic testing. Study risks include risks associated with the study medication including decreased heart pumping, nausea, headache and dizziness. There are also study procedure related risks, and the risk of loss of confidentiality. There may be no benefit but the information learned may benefit others in the future. Study participation will last between 10.5 and 19 months and include up to 13 visits to the study site. Visits will generally last 2-3 hours.

This research is being done to assess whether it is safe and effective to stop oral anticoagulation medications (a blood-thinning medication) during prolonged periods of normal heart rhythm in participants with infrequent episodes of atrial fibrillation (AF).

You may qualify for this study if you have a history of atrial fibrillation (AF) and are currently taking an oral anticoagulant (a blood-thinning medication). You will be randomized to one of two groups: Control Group or Study Intervention Group.

If you are randomized to the Control group, you will be asked to stay on your previously prescribed oral anticoagulant. If you are randomized to the Study Intervention group, you will be asked to take the oral anticoagulant for 30 days only if a prolonged episode of AF is detected on an AF-sensing Apple smartwatch you will be provided.
