SV-ONE represents the integration of NPC-QIC within the existing FON framework. As such, SV-ONE will engage in research and improvement efforts through the entire lifespan of patients with SVHD, including but not limited to those with a Fontan circulation. The larger objective of this study is to increase longevity and enhance the QoL by improving physical health and functioning, mental health and resilience, and neurodevelopment for individuals with SVHD and their families. A longer-term goal of SV-ONE will be to serve as a platform for research and improvement that will
accelerate advances, with the potential to nest clinical trials and to link to registries and programs,
nationally and internationally.

The GRIT-PKP2 study will evaluate the long-term safety and tolerability of LX2020 gene therapy for subjects with PKP2-ACM who have previously received an investigational study medication called LX2020. PKP2-ACM is an inherited heart condition which can cause heart muscle and electrical damage. Investigational means it is not approved for use by the Food and Drug Administration (FDA). There is no investigational treatment being administered in this study. The overall study duration is 4 years. The study consists of 7 visits: a rollover visit, an outpatient monitoring period, (5 visits, 18 months to 48 months after LX2020 administration in Study LX2020-01), and an end-of-study visit. Procedures and activities that subjects will undergo are: quality of life questionnaires, ECG, MRI, ultrasound, ECHO, collection of samples, remote cardiac monitoring, and collection of vital signs.

This study is enrolling participants with symptomatic ATTR-CM (transthyretin amyloidosis cardiomyopathy). ATTR-CM is a rare and serious disease that occurs when a protein in the blood called transthyretin (TTR) builds up throughout the body, including in the heart and nerves. When the abnormal protein, known as amyloid, deposits in the heart, the heart muscle thickens and stiffens, causing the heart to fail. This research study is designed to test whether the medication nucresiran is safe and helps people with ATTR-CM, in comparison to the effects of placebo.

Nucresiran is considered investigational, meaning it is not currently approved by the U.S. Food and Drug Administration (FDA) for the treatment of ATTR-CM. Nucresiran is a TTR silencer. It is like a "quiet button" that turns down the amount of the disease-causing protein that is made. Because there is less TTR, there may be less buildup in the heart and other organs over time.

This is a randomized study meaning once eligibility is confirmed, participants will be assigned by chance, like drawing straws, to either receive nucresiran or placebo. You will have a 2 out of 3 chance of being assigned to nucresiran and a 1 out of 3 chance of being assigned placebo. Placebo is a substance that looks like the actual medication and is given the same way but contains no active substance. The study drug, which can be either nucresiran or placebo, will be given as an injection under the skin in the abdomen (avoiding the area around the navel), thigh, or the side or back of the upper arms. Neither the participants nor the study doctor will know who is assigned to nucresiran or placebo but this information can be made available if need be.

Participation in this study is expected to last for 5-8 years, Study related procedures include physical exams, vital signs, echocardiograms (ultrasound test of the heart), electrocardiograms, (ECG, a tracing of the heart's electrical activity), blood work, urine samples and questionnaires. Participants will also take Vitamin A daily. Study related risks include risks related to the study drug including injection site reactions, abnormal liver function or an allergic reaction. There may be risks related to study procedures including loss of confidentiality. There may not be any direct benefit, but the information learned may benefit others with ATTR-CM in the future.

This study will have a 1:1:1 randomization post the implantation of the WATCHMAN DLX Pro Device comparing three different medications used after the WATCHMAN FLX Pro Device is placed. The goal of this study is to see how safe and effective the medications are after the device is placed. The three different arms include the following: Aspirin only for 12-month study duration, reduce dose non-vitamin K antagonist (VKA) oral anticoagulant (NOAC), either commercially available apixaban (preferred) or rivaroxaban for first 3-months, followed by aspirin, or Aspirin +clopidogrel) for first 6 months followed by aspirin only.

This study is looking for individuals who have resistant hypertension. This is a non-interventional research study and it does not involve a new drug or treatment. The goal of this study is to find out how many people with resistant hypertension, a type of high blood pressure that is hard to control, also have high levels of a hormone called cortisol. High cortisol levels, a condition called hypercortisolism, may make it more difficult to manage blood pressure. If you join the study, you will attend two to three clinic visits. During the first visit, you will go to the clinic for a short checkup. You will have vitals and your medical history reviewed. You will also have a blood draw and be given a pill called dexamethasone which will help us assess your cortisol levels. At your second visit you will fast and have a your blood collected to review your cortisol levels. If necessary, you will be invited for a third visit where you will get a CT scan. The risks associated with the study include bruising, dizziness, or, in rare cases, infection from blood draws, allergic reactions from taking the dexamethasone pill, and exposure to radiation from the CT scan. The study will be completed over the course of 2-3 visits in one months timeframe.

This study is enrolling participants with heart failure, a condition where the heart muscle does not pump blood efficiently, with preserved ejection fraction, meaning the heart muscle contracts (squeezes) normally but is unable to relax appropriately. The study involves implanting a pacemaker, a small device that is placed in the upper left chest, and then programming it to either standard settings or personalized settings for you based on your height and heart function. The programming is randomized, meaning assigned by chance, like flipping a coin so you do not get to choose which group you are in nor does your doctor. The study is trying to determine if using the pacemaker to control your heart rate can help you heart failure.

Your participation will last at least 18 months and may be as long as 4.5 years depending on when you join the study. The study will include about 8 visits and include the pacemaker implant procedure as well as testing such as physical exams, 6 minute walk test, echocardiograms (ultrasound test of your heart), blood work, questionnaires and pacemaker checks.

There are risks associated with the pacemaker implant procedure, risks related to study related procedures and the risk of loss of confidentiality. There may be benefit to you and to others with this condition in the future.

This study is evaluating the clinical safety and efficacy of Prevail Drug-Coated Balloon (DCB) in the treatment of in-stent restenosis (ISR) which is the narrowing of heart arteries (blood vessels) previously treated with stents (mesh like medical device that helps keep arteries open) and in new narrowing of arteries in small vessels. The DCB is a small balloon that has medication on it. The medication is designed to reduce the re-occurrence of narrowing in blood vessels. All participants who have a previous stent will be chosen at random to be treated with either the Prevail DCB or the Agent DCB. You will have a 50:50 chance of being assigned to either DCB. The Prevail DCB is considered investigational meaning it has not yet been approved by the Food and Drug Administration (FDA). The Agent DCB is FDA approved. If you are being treated due to a new lesion in a small blood vessel, you will be treated with the Prevail DCB. Study related procedures include the following: electrocardiograph (known as an ECG, which is a test that shows your heart's electrical activity), blood draws, physical examinations, a review of chest pain, and medication history. Participation in this study will take about 5 years and include about 9 visits. Risks include risks related to the DCBs including allergic reaction, GI symptoms or changes to blood counts.

This registry is enrolling subjects who are indicated for renal denervation to treat high blood pressure that has remained high despite treatment. Renal denervation is a procedure where a catheter (a thin, flexible plastic tube with four electrodes near the end) is placed inside the blood vessels that go to the kidneys. Heat is delivered through the electrodes to disable the nerve activity and lower the blood pressure.

Participation in this registry will last about 1-3 years and include 3-6 visits depending on how often your doctor typically conducts follow up visits. Data will be collected including medical history, medications, blood pressure readings, labs, from the procedure and from any complications if applicable. There is a risk of loss of confidentiality and there may be risks that are not known. There may be no direct benefit but the information learned may help others in the future.

This study is looking at people who have recently had a heart transplant to see if a simple blood test can help doctors better understand how the immune system is doing. By checking tiny molecules called microRNAs in the blood, researchers hope to find a way to tell if a patient might have problems like infection or rejection of their new heart. The goal is to help adjust medications so patients stay healthier after their transplant. The study involves taking blood samples during regular doctor visits over three years, but it doesn't change any of the usual care the patients would already get.

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.
