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 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.

This study is enrolling subjects who are undergoing a planned radiofrequency catheter ablation (RFCA) to treat ventricular tachycardia (VT). VT is a type of irregular heart rhythm originating from the lower chambers of the heart and is commonly treated with RFCA. During a catheter ablation procedure, flexible tubes are guided through blood vessels in your heart where the location of the source of your abnormal arrhythmia is identified. One of the flexible catheters, called an ablation catheter, is then used to deliver energy from its tip to burn the areas of abnormal tissue within the scar which may be causing the ventricular tachycardias. The ablation procedure utilized in this study will be guided by an Ablation Index; a formula developed to assist physicians performing ablation procedures to guide the duration of applications of radiofrequency energy delivery. Participants will be randomized into the control group, where the study doctor will utilize traditional, non-AI guided ablation, or the intervention group, where the study doctor will utilize AI-guided ablation.

This study will last up to 1 year post-ablation procedure for participants and will include up to 4 visits (ablation procedure and 3 follow-up standard of care follow-up visits). Study procedures include the initial, planned ablation procedure, and collection of medical history and images.

The objective of the study is to evaluate the safety and efficacy of the BrioVAD System by demonstrating non-inferiority to the HeartMate 3™ (HM3) LVAS (Abbott) when used for the treatment of advanced, refractory, left ventricular heart failure.

This study is enrolling participants who completed the FARAPULSE ADVENT study and are now nearing the 3 year post atrial fibrillation ablation timepoint. Atrial fibrillation is an irregular heart rhythm caused by electrical signals misfiring. An ablation is a procedure in which those signals are targeted and destroyed to stop the atrial fibrillation. This study will consist of reviewing and collecting medical records since the ablation procedure as well as optional questionnaires and wearing a heart monitor for 7 days to capture the heart's electrical activity. There are no study related follow up visits. Study related risks include loss of confidentiality and possible skin reaction to the electrodes (sticky patches placed on the chest to detect the heart's electrical activity). Individual benefit is not expected but the information learned may contribute to knowledge in this field.

This study is enrolling subjects with tricuspid regurgitation, which is what occurs when the tricuspid heart valve on the right side of the heart does not close properly and blood leaks backwards. Over time this can lead to symptoms like shortness of breath and fluid build up in the legs, abdomen, and lungs. This study involves a new investigational device called the TricValve® Transcatheter Bicaval Valve system to treat the leaky valve. Investigational means it is not approved for commercial use by the Food and Drug Administration. (FDA) This study will last about 5 years and include about 11 visits. Study related procedures include physical exams, right heart catheterization (an invasive procedure to check pressures inside the heart), echocardiograms (ultrasound test of the heart), CT scan, blood work, questionnaires, hall walk test and procedure to place the device. Risks include those related to the device and procedure such as infection, failure of the device, worsening of your symptoms or other cardiac complications. There are also risks associated with study testing such as radiation risks, blood draw risks, loss of confidentiality and unknown risks. There is potential benefit to you and to others in the future from what is learned from this study.
