This study is enrolling participants with severe aortic stenosis, which is narrowing of one of the heart valves. This condition reduces the amount of blood that can get to the body. This study is collecting data on the safety and effectiveness of an investigational (not yet approved for commercial use by the US FDA (Food and Drug Administration)) device called the ACURATE Aortic Valve System. The procedure to place the device, referred to as TAVR - transcatheter replacement of aortic valve is done in place of open heart surgery. In this study the ACURATE Aortic Valve System will be compared to two commercially available Aortic Valve Systems (valve replacement systems). Participants will be randomized (assigned by choice, like a flip of a coin, in a 1:1 fashion so 50% chance of being assigned to either group like the flip of a coin) to one of two groups. One group will receive the ACURATE Aortic Valve System while the other group will receive one of the commercially available systems. This study will last up to 10 years. Pre-procedure testing is done and reviewed by an eligibility committee to confirm you qualify. Study visits will occur prior to your procedure, during the procedure and throughout your hospital stay, and prior to discharge. Additional visits will occur 1 month and 6 months after your discharge, and then you will either seen or telephoned once per year for the next ten years. Study related testing includes CT scans, physical exams, echocardiograms (ultrasound test of the heart), blood work, and questionnaires.

This study is examining the use, safety and performance of an investigational, meaning not approved for commercial use or sale by the US Food and Drug Administration (FDA) device called Transcatheter Mitral Valve Replacement (TMVR). The TMVR is a device used to treat mitral valve disease in patients with heart failure (weakened heart muscle). The device is placed by a non surgical approach using a delivery catheter (hollow tube) placed in your blood vessel at the top of your leg and directed up to your heart. This five year study will include a screening process to determine you meet eligibility criteria. If you qualify you will then be seen for a baseline visit, undergo the procedure to place the device, day after procedure, at hospital discharge, 1,3,6, 12 months, then yearly for up to 5 years. Study related testing includes physical exams, medication review, 6 minute hall walk test, questionnaires, blood work, CT scans, electrocardiogram or ECG (recording of your heart's electrical activity) and echocardiogram (ultrasound test of your heart).

This study is being done on patients who have heart failure, a condition where the heart muscle weakens and enlarges and cannot pump blood effectively. The purpose of this study is to assess the safety and effectiveness of a new device called the AccuCinch Ventricular Restoration System and compare it to treatment with standard heart failure medications alone. The AccuCinch Ventricular Restoration System consists of anchors, which attach to your heart muscle, sliders to connect the anchors and a thread like cord that goes through the anchors and is cinched to make your enlarged heart smaller so it can pump more efficiently. The device is implanted in one of the lower pumping chambers of the heart (called left ventricle). The study will have two groups, the treatment group in which participants undergo the device implant in addition to taking heart failure medications and the control group in which participants are treated with heart failure medications alone. Participation will last up to 5 years.

The goal of the COSMID (Comparison of Surgery and Medicine on the Impact of Diverticulitis) trial is to determine if elective colectomy is more effective than best medical management for patients with quality of life-limiting diverticular disease. The COSMID trial focuses on both patient-reported outcomes and clinical outcomes that matter to patients. The results are expected to establish an evidence-based approach to the care of millions of patients per year in the United States and help people impacted by this common condition make more informed treatment decisions.

The purpose of this study is to determine whether a new medical technology can help reduce post-operative total knee or hip pain when combined with a Cognitive-Behavioral intervention (CBI).

This new medical technology, is called transcranial direct current stimulation (tDCS), it uses a very small amount of electricity to temporarily stimulate specific areas of the brain thought to be involved in pain reduction. The electrical current passes through the skin, scalp, hair, and skull and requires no additional medication, sedation, or needles.

This study will investigate the effects of tDCS, the Cognitive-Behavioral (CB) intervention and their combination on pain among veterans following total knee arthroplasty (TKA) or total hip arthroplasty (THA). You may benefit in the form of decreased pain and opioid requirements following your knee or hip replacement surgery. However, benefit is only likely if you are randomized to one of the 3 (out of 4) groups.

This study hopes to determine the effects of these interventions and their combined effect on post-operative pain, opioid use and functioning during the 48-hour post-operative period following a total knee or hip replacement.

This study is being done to evaluate the impact that monitored anesthetic care (MAC) versus general endotracheal anesthesia (GETA) has on hospital length of stay, rate of ICU admission, or procedural mortality. Also, we hope to determine if the use of Transesophageal Echocardiography (TEE) during GETA impacts device success and durability. Adult patients undergoing transfemoral approach TAVR for aortic valve stenosis may be eligible candidates for this study.

Pain control after tonsillectomy is imperative but often difficult. Current post-operative pain medication regimens include opioid analgesics and are often still inadequate. Though not standard of care, it is our practice to prescribe a single dose of oral steroid medication on the third day after surgery, when pain and swelling are at their peak, in order to assist with pain control and reduce opioid consumption. Though this practice has a rational theoretical basis, there is no prospective data supporting or discounting it. We aim to compare pain control, opioid consumption, and complication rates in children receiving post-operative steroids versus those who do not.

Transcranial direct current stimulation (tDCS) has shown the potential to improve symptoms in patients with motor deficits, however its effects have not been consistent in randomized studies to date, limiting widespread adoption of this technology. A critical gap in our knowledge is a detailed understanding of how tDCS affects motor areas in the brain. We propose using tDCS while recording directly from motor cortex using subdural electrocorticography (sECoG) in patients undergoing deep brain stimulation surgery. We expect this novel approach to broaden our understanding of tDCS application and possibly lead to therapeutic advances in this population.

The purpose of this study is to collect and evaluate clinical and radiographic outcomes data on patients who have undergone, or will undergo, shoulder replacement surgery. Patients who receive a device from the Equinoxe® Shoulder System, manufactured and distributed by Exactech, Inc as well as patients who receive a device from another shoulder arthroplasty system may be included in this study.
