This study is recruiting patients who have an acute (very sudden onset or rapid change, within 2 weeks), complicated type B aortic dissection. One way to repair an acute, complicated type B aortic dissection is with an endovascular stent-graft. A stent-graft is a polyester fabric tube (graft) sewn onto metal springs (stent). The stent-graft is compressed inside a narrow plastic tube called a delivery system, which is inserted into the blood vessels in the groin area (femoral/iliac artery) and then threaded through the blood vessels to be placed at the area of the dissection inside the aorta.This research study will assess and evaluate safety and performance of an endovascular stent graft called the RelayPro Thoracic Stent-Graft System (the “Study Device”). The Study Device is investigational, which means it is still being tested and is not approved by the Food and Drug Administration (FDA) for sale in the United States.We expect that participants will be in this research study for approximately 5 years after their endovascular repair procedure. Participants will return to clinic at 1-month, 6-months, and 1-year, and then annually out to 5 years. These visits are considered part of standard care, and the results of test done at these visits will be recorded for the study.We expect up to 5 people here will be in this research study out of 80 people in the entire study nationally.
A Prospective, Single-Arm, Multicenter Study to Investigate the Safety and Effectiveness of SAPIEN 3 Transcatheter Heart Valve Implantation in Patients With a Failing Aortic Bioprosthetic Valve
This study will evaluate the safety and effectiveness of the Edwards SAPIEN 3 Transcatheter Heart Valve (TH…
This study will evaluate the safety and effectiveness of the Edwards SAPIEN 3 Transcatheter Heart Valve (THV) Model 9600TFX and associated delivery systems for the aortic valve in valve procedure. Participants in this study will have the investigational (experimental) Edwards SAPIEN 3 transcatheter aortic heart valve (study device) to replace the failing bioprosthetic aortic valve access through the heart through a small incision is in the chest. The study device and its delivery system are investigational, which means they are not approved for commercial use by the U.S. Food and Drug Administration (FDA) for the valve in bioprosthetic valve procedure. The previous generation of SAPIEN valves, SAPIEN XT, was approved for commercial use by the FDA for a failed surgical bioprosthetic aortic valve in October 2015. The study device is a bioprosthetic heart valve made out of man-made materials and animal tissue. It is an artificial device made to replace the diseased aortic heart valve. Each valve consists of a stent (mesh tube made of metal) to hold the study device in its intended position and valve leaflets (made of biological material derived from cows) to direct the flow of blood in the heart. Study participation will last approximately 10 years. Participants will be asked to come to clinic for study visits at 30 days, 6 months, and 12 months after the study procedure and then annually until 10 years after the procedure. We expect up to 19 people will be enrolled at Northwestern. The study expects to enroll up to 125 people internationally.
*Main Inclusion Criteria*
Failing surgical or transcatheter bioprosthetic valve in the aortic position demonstrating ≥ moderate stenosis and/or ≥ moderate insufficiency.
*Main Exclusion Criteria*
Surgical or transcatheter valve in the mitral position (mitral rings are not an exclusion).
Severe regurgitation (>3+) or stenosis of any other valve.
Failing valve is unstable, rocking, or not structurally intact.
Evaluation of Transcatheter Aortic Valve Replacement Compared to SurveilLance for Patients with AsYmptomatic Severe Aortic Stenosis: EARLY TAVR trial
The main reason for the study is to determine whether aortic valve replacement with the Edwards SAPIEN 3 THV (the “Study Device”) is helpful for pa…
The main reason for the study is to determine whether aortic valve replacement with the Edwards SAPIEN 3 THV (the “Study Device”) is helpful for patients who have severe, calcific, aortic stenosis (a narrowing of the aortic heart valve, where calcium has attached to the valve surface, resulting in obstructed blood flow) and do not have symptoms. The Study Device is a bioprosthetic heart valve. It is an artificial device made to replace your diseased aortic heart valve. Each valve consists of a stent (mesh tube made of metal) to hold the valve in position and valve leaflets (made of biological material derived from cows) to direct the flow of blood in your heart. The Study Device and its delivery system are not approved for commercial use by the U.S. Food and Drug Administration (FDA) in patients that do not have symptoms of aortic stenosis. To date, more than 12,000 patients have been enrolled in clinical studies with an Edwards THV. The SAPIEN 3 THV that is being investigated for this study has been implanted in over 3,000 patients with symptoms of severe aortic stenosis and has been approved by FDA for those patients. Participation in the study will vary, depending upon the treatment group you are assigned. If you are in the TAVR group, your participation will be for 5 years. If you are in the Clinical Surveillance group, your participation could range from 5 to 10 years. If you are in the registry group, your participation will be for 5 years. We expect up to 166 people will participate in the main study and up to up to 150 in the registry here at Northwestern. A total of 1109 patients will participate in the main study and up to 1000 patients will participate in the registry internationally.

The purpose of this research study is to find out if PerClot is safe and effective as a part of surgery to stop bleeding. PerClot is a device in granule form made from the starch of a potato. The starch has been engineered in a way that the powder absorbs water and helps to form a clot. This kind of device (topical hemostat) is intended for use in surgical procedures as an adjunctive hemostatic device when control of capillary, venular, and arteriolar bleeding by pressure, ligature, or other conventional procedures is ineffective or impractical. PerClot is left in your body after surgery. In animal studies, it has been found that PerClot is absorbed by the body in a few days after surgery. This has not been demonstrated in humans and can vary depending on the amount of device applied. This can also depend where it is applied. This research study will collect follow-up data after PerClot is used. PerClot is an investigational device in the United States. This means it has not been approved by the Food and Drug Administration (FDA). PerClot has been an approved medical device in Europe since 2008. This research study plans to enroll approximately 324 study participants at approximately 25 U.S. sites, including approximately 10 people from this institution. We expect that participants will be in this research study for approximately 6 weeks; however, if you currently have, or are diagnosed with cancer during the study, you will be contacted by the study coordinator on the telephone at 24 months after your surgery to ask questions about your general health.

Annular ReduCtion for Transcatheter Treatment of Insufficient Mitral ValvE (ACTIVE): A prospective, multicenter, randomized, controlled pivotal trial to assess transcatheter mitral valve repair with Edwards Cardioband System and guideline directed medical therapy (GDMT) compared to GDMT alone in patients with functional mitral regurgitation (FMR) and heart failure.
This study is enrolling patients with moderate-to-severe or severe functional mitral regurgitation (FMR). FMR occurs when the two leaflets of the mitral valve do not close properly, causing blood to leak backward with each heartbeat. Since some of the blood leaks backward, the heart has to pump more blood with each beat to push the same amount of blood forward. This can lead to shortness of breath and make the heart weaker because it cannot pump enough blood for the body’s needs. The purpose of this study is to evaluate a new device to treat patients who might benefit from repair of their mitral heart valve due to functional mitral regurgitation. The device is called the Edwards Cardioband System (“Edwards Cardioband System”). The device is investigational, which means it is not yet approved by the U.S. FDA for sale in the United States. This device is placed without the need for an open-heart procedure and without the need for a heart and lung machine. Instead, the device is delivered using a less invasive approach where the Cardioband System is inserted through a vein in the groin and threaded to the heart using a delivery catheter (small plastic tube). For this study patients will be “randomized” or assigned by chance to one of two study groups: Device group or the Control group. Patients will be randomized 2:1, which means each patient has a 2 to 1 chance of being assigned to the Device group (twice as likely to be in the Device group as the Control group). Subjects assigned to the Control Group may be eligible to receive the Study Device after their 1 year study visit. Participation in this study will last for approximately 5 years. Both Device and Control Group participants will be asked to return for visits at 1 month, 6 months, and 1, 2, 3, 4 and 5 years. This study is being conducted in up to fifty (50) hospitals in the United States, Canada, and/or Europe and plans to enroll up to 525 participants, including approximately 10 people from this institution
APOLLO Trial Clinical Investigation Plan - Transcatheter Mitral Valve Replacement with the Medtronic Intrepid™ TMVR System in patients with severe symptomatic mitral regurgitation
This study is enrolling subjects with severe symptomatic mitral regurgitation to test a new investigational device for …
This study is enrolling subjects with severe symptomatic mitral regurgitation to test a new investigational device for mitral regurgitation. The new investigational device is a mitral valve replacement called the IntrepidTM Transcatheter Mitral Valve Replacement (TMVR) System. The purpose of the TMVR device is to function similarly to a standard bioprosthetic (man-made) valve implant in that it allows blood to flow only in the forward direction, relieving mitral regurgitation. A standard valve implant, however, is sewn directly into the heart during surgery in which the chest is fully open, the patient is put on heart-lung bypass support and the heart is temporarily stopped to sew in the valve. The TMVR device is intended to be placed through a less invasive procedure, without sewing, and without requiring heart-lung bypass support or stopping the heart.
INCLUSION: 1) Subject has severe symptomatic mitral regurgitation as defined by the ASE. 2) Patient is a candidate for bioprosthetic mitral valve replacement EXCLUSION: 1) Prior mitral valve surgery including previously implanted mitral valve, ring, or band. 2) Heart Team agrees predicted risk of operative mortality is <3% at 30 days or has ≥35% risk of mortality or irreversible major morbidity at 30 days. 3) mitral anatomy that would preclude management of the sub-valvular apparatus and/or full chordal sparing

This study is recruiting patients with tricuspid regurgitation (a condition in which blood flow through the tricuspid valve of the heart flows in the wrong direction) that may benefit from a new tricuspid valve reconstruction system. This is an early feasibility clinical research study that will evaluate the safety and performance of the Edwards Cardioband Tricuspid Valve Reconstruction System, (the “Study Device” ). The Study Device includes an adjustable implant that is delivered and anchored to the tricuspid valve by a transfemoral delivery system, meaning it is inserted in a minimally invasive procedure through a puncture into a vein in the leg. The Cardioband Implant will be positioned around the tricuspid valve and will be adjusted to reduce the size of the valve, thus improving the tricuspid regurgitation. Up to 15 patients will be enrolled in this study at up to 15 sites. All enrolled study patients will be assessed at the following intervals: screening/baseline, procedure, discharge, 1 month, 6 months, 1 year and annually for 5 years post implant procedure.
17-518: The MitraClip® EXPAND Study A Contemporary, Prospective Study Evaluating Real-world Experience of Performance and Safety for the Next Generation of MitraClip® Devices
This study is being conducted to collect information on the use and outcomes of the MitraClip System in everyday medical treatment.
Participating in this study will not impact the treatment that you receive for your MR. Information about your health and the results of your treatment with the MitraClip system will be collected and documented during the implantation procedure, while you are in the hospital,and from your regularly scheduled clinic visits at 30 days and 1 year after the implant. You will not need to come in for extra visits or have additional procedures done for the study. Study staff will call you 6 months after the implant to ask how you are feeling and if you have had any problems or side effects.
This study is recruiting patients who will be receiving a MitraClip System device as part of their standard care for mitral regurgitation (MR).

The BEST-CLI study This study is recruiting participants diagnosed with peripheral artery disease (PAD) that has led to critical limb ischemia (CLI). In CLI, arteries that deliver blood to the leg and foot are narrowed or blocked by plaque buildup (atherosclerosis). CLI can cause pain in the foot or leg even when sitting or lying at rest; it also can cause foot and leg ulcerations, and can sometimes lead to gangrene and loss of the leg. CLI is usually treated by operations or procedures that increase blood flow to the leg and foot, in order to relieve these symptoms, heal the ulcers, and preserve the limb. There are two different ways to increase the blood flow in CLI. One is with open surgery, which creates a bypass around the blockage. The other is with endovascular treatment (often called angioplasty), a minimally invasive procedure that opens the blocked arteries directly. Angioplasty is performed with balloons and other tools that clear plaque, and sometimes permanent implantation of small, mesh-like metal tubes called “stents”. Both types of treatment – open surgery and angioplasty - are considered reasonable and appropriate for patients with CLI. Half of the participants in this study will have open surgery and half will have endovascular treatment. The assignment of treatment is random, meaning purely by chance (50:50, just like a coin toss). The purpose of the study is to learn about which therapy is more suitable for those patients who are candidates for both open surgery and endovascular treatment, and to provide information regarding cost effectiveness of the two different types of treatment. We expect 2100 participants to enroll from approximately 120 different study centers across the United States, Canada, and possibly other countries. We hope to enroll up to 20 participants at Northwestern.

Carotid revascularization for primary prevention of stroke (CREST-2) is a multicenter, randomized controlled trials of carotid revascularization and intensive medical management versus medical management alone in patients with asymptomatic high-grade carotid stenosis. One trial will randomize patients in a 1:1 ratio to endarterectomy versus no endarterectomy and another will randomize patients in a 1:1 ratio to carotid stenting with embolic protection versus no stenting. Medical management will be uniform for all randomized treatment groups and will be centrally directed.

This research study is recruiting patients who have one of the following conditions: 1. A bulge in your aortic wall (aneurysm) caused by weakening in the aortic wall. Over time, this bulge may continue to grow larger and could rupture. 2. A tear in your aortic wall (dissection). Blood flows through this tear, causing the layers of the aortic wall to separate (dissect) and create a new channel for blood flow. This channel may continue to grow and could rupture. 3. Bleeding and blood clots within your aortic wall (intramural hematoma). This can lead to weakening of the aortic wall and aortic rupture. 4. A lesion (wound) or ulcer in your aortic wall caused by aortic disease and can progress and lead to an aortic aneurysm, dissection, or rupture. 5. A traumatic injury to your aorta that can result in a tear, lesion, or rupture of the aortic wall. The aorta is the main artery in the human body that carries oxygenated blood to all parts of the body. Disease of or injury to the aorta can be a life threatening condition The study will look at treating these aortic diseases and injuries with a new medical device called the GORE® TAG® Thoracic Branch Endoprosthesis (TBE Device). Depending on the location of your aortic disease or injury, the study device will be implanted inside your aorta and one of the main arteries that branches off your aorta supply blood to the brain and arms. Study participants will be expected to return for follow-up visits with the Study Doctor at one (1), six (6), 12, 24, 36, 48, and 60 months following the procedure. This research study plans to enroll up to 435 study participants at approximately 40 sites across the country, including up to 5 people from this institution.

An Abdominal Aortic Aneurysm (AAA) is a balloon-like expansion of the aorta, the large artery that transports blood from the heart to the rest of the body, in the abdominal area just below the kidneys. As part of routine monitoring care for patients diagnosed with AAA, at least semi-annual evaluations are performed using imaging methods such as a computed tomography (CT) scan. Magnetic Resonance Imaging (MRI) is another method of creating pictures of the same vessels seen on a CT scan. MRI is a method for producing extremely detailed pictures of blood vessels without the need for x-rays. Radio waves, along with the magnetic field of a large magnet within the MRI machine, are used to make the pictures. MR images are used to detect and aid in the diagnosis of heart disorders and blood vessel diseases. For the purpose of this research, along with the routine CT scan, an additional scan called a ECG-gated MRI exam will be performed. This MRI exam does not involve any contrast, a dye used to make tissues, abnormalities or diseases processes more visible. This one-time MRI exam will be performed prior to anticipated elective AAA repair or during the course of periodic surveillance for AAA. This research study plans to enroll approximately 200 study participants at approximately 3 sites, including approximately 100 people at Northwestern.
Participants may be eligible for this study if they have been diagnosed with an Abdominal Aortic Aneurysm and either have been recommended to undergo elective repair or are currently under periodic surveillance for AAA.
