This study is seeking participants with arrhythmogenic cardiomyopathy (ACM), also known as arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C), due to a genetic abnormality known as a PKP2 variant. ARVD/C is an inherited disease where the muscle tissue in the right ventricle, one of the lower pumping chambers of the heart, dies and is replaced with scar tissue. This causes a weakened heart muscle and disrupts the heart's electrical system which can lead to heart failure and/or fatal heart rhythms. This study is looking at the safety and effectiveness of an investigational medication, meaning it is not yet approved for use by the Food and Drug Administration (FDA). The study medication is a gene therapy called LX-2020, and is designed to add new PKP2 genes to replace the faulty ones so your cells can make the correct PKP2 genes. The study medication is given via an intravenous (IV) line meaning in a vein. Participation in this study involve up to 25 visits including a hospitalization over the course of 1 year with an additional 4 years of follow up afterwards. Study related procedures include a variety of heart testing like electrocardiogram (ECG), echocardiogram, a test that records a tracing of the heart's electrical activity, Echocardiogram, (echo) a test that uses ultrasound to capture moving images of the heart, magnetic resonance imaging (MRI), a test that shows an image of the heart and surrounding structures, sample collection including blood, urine, tissue, nasal mucus, saliva and stool, liver ultrasound, questionnaires, physical exams, and at least a two night stay in the hospital. Medications to suppress (meaning weaken) the immune system, before receiving the LX2020 are also required. Risks associated with gene therapy include an immune response that may cause inflammation in the liver, heart or other organs. It may damage red blood cells, cause a low platelet count or cause the formation of small blood clots. There are also risk related to the study procedures including bleeding associated with the heart biopsy, risks related to drawing blood, risks of radiation, and loss of confidentiality. There is potential benefit and in the future, others with ACM may benefit from the knowledge gained from this study.

The purpose of the study is to evaluate the safety and how well the medication levosimenden works versus placebo in treating Pulmonary Hypertension and Heart Failure with a Preserved Ejection Fraction measured by a 6 minute walk. This is a condition where the lower left chamber (left ventricle) of the heart is not able to fill properly with blood during the filling phase and the amount of blood pumped out to the body is below normal. 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. Levosimendan is a drug that has been FDA-approved for intravenous (IV) delivery to your body. This study aims to determine if the tablet form of the drug is as effective as the IV route. Tablets are much more attainable for patients to manage their heart failure from home, rather than going to an infusion clinic for treatments. Participation in this study will last approximately 12 weeks with the option to continue to the stage 2 phase of the study. If the stage 2 phase is selected as well, participation will last approximately 26 months or a little over 2 years. These visits will include such activities as blood tests, questionnaires, physical evaluation by a study doctor, echocardiogram, and 6 minute hall walks.

Participants will be randomized to either the treatment group (and receive the medication) or the control group (receive an inactive 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 drawing straws). 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.

A randomized clinical trial study that compares 2 different timepoints to clamp the cord at birth. The study involves babies with heart disease born between 37 0/7- 41 6/7 weeks of pregnancy. Doctors will clamp the umbilical cord around 30 seconds (between 1-<60 seconds) after birth vs. around 120 seconds (between 60-<180 seconds) after birth. Doctors consider both treatment groups to be "usual care." A goal of this study is to find out which umbilical cord clamping timepoint is best for babies with heart disease.

This is a study to evalaute the device's safety, function, and effects on heart function, and clinical outcomes of using the Edwards APTURE system (study device) in subjects with heart failure.

Major study activities include 3 right heart catheterizations (RHC) with exercise, a computed tomography (CT) scan with 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.

The information obtained from this study will show how safe and effective this approach is in treating the symptoms of heart failure. Alternative treatment for heart failure depends on the cause, but may include diet and exercise, managing stress, medication (such as medications to treat leg swelling, high blood pressure, or abnormal heart rate), participation in another research study or continuing with current medical therapy

This study will include all adult (18 years or older) patients who received a heart transplantation at MUSC. This study will conduct a chart review of all adult heart transplant participants to understand how different variables including, donor and recipient comorbidities, donor and recipient medical history, donor and recipient social determinants of health, recipient length of time on transplant waitlist, donor cause of death (morbidity), donor conditions when harvested, recipient presence of mechanical circulatory support (MCS) (temporary or permanent), recipient reason for transplant, recipient use of inotropes and/or vasopressors, recipient pre-transplant lab values, recipient pre-transplant ECHO, recipient pre-transplant right heart catheterization (RHC), donor lab and test values, other donor and recipient imaging studies, recipient surgical time and patient stay data, donor-recipient prediction heart mass (PHM) ratio, recipient medications, donor medications, post-transplant follow-up data, as well as other donor and/or recipient variables, will affect heart transplant outcomes.

This is a study comparing the new class anticoagulants factor XIa to the FDA approved Apixaban. The study is to determine if Milvexian is as effective and safe with preventing clots for patients with A-fib and to determine if Milvexian is better at reducing the chances of bleeding.

The study is being done to test the use of a drug called bromocriptine for women who have a condition called Peripartum cardiomyopathy or PPCM. PPCM means you have a weak heart after giving birth. The study will look at how the heart muscle improves in women taking bromocriptine compared to a group of women given a placebo or inactive pill. Bromocriptine is approved by the United States Food and Drug Administration (FDA) to treat irregular periods and other symptoms that result from having high blood levels of a substance called prolactin. It is not approved for use in usual care to treat PPCM. The follow up period will be about 3 years. The study will have an initial visit and then the follow -up visits will take place at one, three, six, and 12 months in the first year and visits by phone at 24 months and 36 months.

This study is enrolling adults between the ages of 18-60 who have a Patent Foramen Ovale (PFO). A PFO is a slit-like opening between the upper chambers (called atria) of the heart. This opening allows blood to flow between these chambers which can lead to a stroke. This study is examining an investigational device called the Encore PFO closure device. An investigational device is one that is not yet approved for commercial use by the US Food and Drug Administration (FDA) but is approved for use in this study. This study will last approximately 5 years and involve 9 visits. This is a randomized study meaning participants will be randomly assigned to receive the investigational PFO closure device or an FDA approved PFO closure device. Participants have a 50:50 chance to receive either device. Study related testing includes physical exams, blood test, echocardiogram (ultrasound test of the heart) electrocardiograms or ECG (test of the electrical activity of the heart) and the procedure to place the PFO closure device. There are risks involved with this study including access site related risks, bleeding and bruising, incomplete closure of the PFO with the closure device or other device related complications. There is potential benefit including reduced risk of a recurrent stroke.

There are two classes of drugs for preventing blood clots in patients with atrial fibrillation (AF), an irregular heartbeat, after cardiac surgery: antiplatelet drugs (like aspirin) and anticoagulants (blood thinners). This study aims to determine whether the addition of blood thinners to antiplatelet drugs will improve treatment outcomes in patients who develop AF after coronary artery bypass grafting (CABG) surgery.

In this study, you will be randomized (assigned to a group by chance--like flipping a coin) into one of 2 study groups; the assignment to receive the antiplatelet drug alone or the antiplatelet drug plus a blood thinner.

Before discharge from the hospital, you will undergo an electrocardiogram (ECG), which examines the electrical activity of your heart. At 1 and 2 months after randomization, you will receive a phone call from the study staff. At 3 months after randomization, you will return to the institution where you received your surgery for an in-person visit. At 6 months, you will receive a phone call from the study staff. Your total participation will be about 6 months.
