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.

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.

This proposal is to contribute to data registry and sample bank called Pediatrics Biorepository for Cardiology Clinical Research. Samples collected in this study may be used for future research which plan to advance the state of science in the hopes to develop new ways to diagnose and treat children affected with heart conditions.

Over 2400 people who have sickle cell disease and are between the ages of 15 and 45 have been enrolled into the National Registry (SCDIC-I) of patients with Sickle Cell Disease (SCD). A rich resource of natural history data, the SCDIC-I Registry has longitudinal data collected yearly since 2016 from patient surveys (e.g. self reported pain incidences, sleep, barriers to care, experiences during and after pregnancy), medical record abstraction (e.g. medications, transfusion history, co-morbidities) and laboratory results. The 150 patients (or 1200 among the 8 sites) will be selected from both MUSC adult and pediatric SCD clinics starting at 12 years of age; those not previously enrolled in the SCDIC National Registry will be offered the possibility to enroll in SCDIC-II.
We will look at the following:
1- Compare the effect of new SCD medications – crizanlizumab, voxelotor, and L-glutamine – on clinical outcomes in individuals with SCD.
2 - Identify genetic and genomic predictors of response to crizanlizumab, voxelotor, and L-glutamine
3 - Integrate study data into the CureSCi metadata catalog (MDC) to enhance future cross-study analyses.

The PK Papyrus Covered Coronary Stent System is a Humanitarian Use device (HUD) approved for the use of acute perforation in native coronary vessels or coronary bypass grafts in vessels 2.4-5.0mm in diameter. In an emergency situation, PK Papyrus may be used emergently outside its' approved indications if a patient has a life threatening condition that needs immediate treatment and no generally acceptable alternative treatment for the condition exists.

This study will compare WATCHMAN FLXTM ("DEVICE") to a category of OAC called non-vitamin K antagonist oral anticoagulation, also known as NOACs ("CONTROL"). NOAC medications include Pradaxa® (dabigatran), Eliquis® (apixaban), Xarelto® (rivaroxaban), or Savaysa® (edoxaban).The study will research the safety and effectiveness of the WATCHMAN FLXTM device compared to treatment with NOAC therapy to determine if it works for patients with your type of atrial fibrillation who require treatment for potential blood clot formation (thrombus) in the LAA.

The purpose of this study is to evaluate the safety and effectiveness of the JenaValve Trilogy™ Heart Valve System in a patient population with symptomatic severe Aortic regurgitation ( a condition where the heart's aortic valve does not close tightly and allows some blood to leak back into the heart chamber) requiring replacement/repair of their native aortic valve that are at high risk for open surgical aortic valve replacement/repair (SAVR).

Your involvement in this study will last approximately 5 years from the time of your procedure. The visits include: Screening/Baseline, Procedure, Pre-Discharge, 1 month, 6 months and annualy for 5 years

Patients with cardiovascular disease (CVD) are at increased risk of depression following hospital discharge. Unfortunately, most depressed CVD patients do not receive appropriate care for their depression, often because they are unable to, or are fearful of traveling to providers for the regimen of 8-12 weekly visits of therapy such as Behavioral Activation (BA). This study will compare the effectiveness of BA for depression, delivered via Telehealth, to standard post-CVD hospital discharge best practices. It is predicted that patients who receive BA will have better mental health outcomes and will be less likely to be re-hospitalized compared to patients who receive standard post-discharge care.

Underserved, racial and ethnic minority communities are experiencing higher rates of COVID-19 cases and associated mortality compared to whites due to long standing social and structural inequities that also drive disparities in chronic diseases such as stroke, cardiovascular disease, diabetes, and hypertension. Patients with underlying chronic diseases who are recovering from COVID-19 depend on the support of family and friends (informal caregivers/care partners) who are being exposed to the same pandemic and racial stressors, exposure that can affect the health and quality of life of both partners. The primary goal of this study is to test the efficacy of an adapted, telehealth-enhanced intervention that targets barriers impacting family illness management behaviors of Black/African American (AA) adult COVID-19 survivors and carepartner dyads for improved quality of life and COVID/chronic illness health related outcomes.

This study will include volunteers diagnosed with a form of heart failure that is characterized by a weakened heart muscle that appears to be pumping in a normal manner. This condition is called "heart failure with preserved ejection fraction" or HFpEF. For these individuals, it has been determined that the health problems and symptoms experienced may be due to a significant increase in the pressure of one of the chambers of the heart. This pressure build-up causes a variety of symptoms, including tiredness, difficulty breathing, and reduced ability to exercise/walk.

This study is to help evaluate a new device (the "Satera Ablation System") designed to reduce the build-up of pressure described above. The Satera Ablation system is a catheter used to ablate or destroy the splanchnic nerve on one side of the body. The Sponsor believes by destroying this nerve there may be some reduction in the symptoms caused by HFpEF. The procedure using the Satera Ablation System will be performed in the catheterization lab and does not involve surgery. Participants will stay overnight in the hospital following the procedure for observation.

The length of subject participation in the study will be approximately 24 months and includes 5 office visits, 1 phone call and 2 procedures. Participants in this research study will be randomized to either the treatment group or the control group and have a 2:1 chance of receiving the research treatment with the Satera Ablation System at the time of randomization.

This study will help us learn more about how safe and effective the Satera Ablation System is in treating the symptoms of patients with HFpEF.
