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. Principal Investigator Malaisrie, S. Chris Location(s) Map it 201 E.

A separate study cohort (MAC Cohort) will enroll subjects with at least moderate symptomatic mitral regurgitation combined with mitral stenosis in the presence of mitral annular calcification (MAC). The new investigational device is a mitral valve replacement called the Medtronic 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 IntrepidTM 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. Participation in this study will last for approximately 5 years. Participants will be expected to attend a minimum of 7 in-person scheduled study visits after discharge from the hospital at 1, 6, 12, 24, 36, 48 and 60 months after the procedure. Eligibility CriteriaEnrolling participants with mitral valve regurgitation who are at high risk of experiencing major complications while undergoing open-heart surgery due to their current medical conditions or anatomical reasons (relating to how and where the heart, mitral valve, and blood vessels are placed within the body). Additionally, physicians have determined that these participants may not be optimally treated with currently approved transcatheter repair therapies. Principal Investigator Malaisrie, S.

The MitraClip System uses a less … The purpose of this research study is to compare health outcomes of patients diagnosed with Primary MR who have their MV repaired with open heart surgery, which is the current standard treatment, to patients who have their Mitral Valve repaired with the MitraClip System. The MitraClip System uses a less invasive procedure to repair the mitral valve. Subjects are asked to participate in this Study because they have moderate-to-severe or severe MR and it has been determined to have symptoms due to heart failure despite being treated with currently available therapies. MR occurs when the 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 needs to pump more blood with each beat to push the same amount of blood forward. The Study will enroll approximately 500 subjects at up to 60 sites in Europe, United States, and Canada. The Study consists of two arms: Device Arm and Control Arm. Eligibility Criteria Subject has severe (Grade III or greater per the ASE criteria, which includes severitygrades of 3+ and 4+) primary MR (mixed etiology is acceptable provided theprincipal mechanism of action is a degenerative mitral valve) as assessed bythe ECL. Subject is at least 75 years of age Principal Investigator Davidson, Charles J Location(s) Map it 201 E.

Using vaccines to train the body’… Lynch Syndrome (LS) increases the risk of colon cancer and can also increase the risk of other cancers, including cancer of the uterus, ovaries, small bowel, stomach, pancreas, urinary tract, skin and brain. Cancer prevention strategies for people with LS are therefore urgently needed. Using vaccines to train the body’s own immune system to prevent polyps and cancers is a new approach that we plan to test in patients with LS. We are asking you to take part in this research study because you have been diagnosed with Lynch syndrome and your doctor has previously found polyps or cancer in your colon or rectum. This study is being done to find out if we can lower your chance of getting colon cancer and other Lynch cancers by giving you three vaccines, an approach called Tri-Ad5, in combination with an injectable immune-enhancer protein called N-803. The usual approach for patients with Lynch syndrome is to be followed closely by their doctor with regular colonoscopies, pelvic imaging (ultrasounds), urine tests, computerized tomography scans (CT scans), and skin examinations to watch for the development of cancer. Removal of the colon or uterus before cancer develops is also part of the usual approach. We are doing this study because we want to find out if the vaccines we are testing will be effective at preventing colon polyps and cancers of the colon and other organs. The purpose of this study is to compare the safety and effects of the Tri-Ad5 vaccines alone, or in combination with N-803, versus placebo on the risk of developing colon and other cancers in patients with Lynch syndrome. The Tri-Ad5 vaccines and N-803 are not FDA-approved. This study is looking for volunteers who have been diagnosed with Lynch syndrome. We will enroll 158 participants at institutions across the country. Eligibility Criteria You may be eligible if: You have been diagnosed with Lynch syndrome and have had abnormal growths in your colon or rectum You have not had any cancer treatment in the past 6 months · You are 18 years or older · You are not pregnant or planning to get pregnant Principal Investigator Muller, Charles M ClinicalTrials.gov IdentifierNCT05419011IRB number STU00217456 More Info Keywords lynch syndrome vaccine cancer prevention colon cancer Tri-Ad5 immunoprevention LS Copy Study URL to Clipboard Copy

This research … This study is enrolling patients who have an aortic aneurysm involving the visceral branch blood vessels (vessels that provide blood to the kidneys) that requires treatment. The aorta is a large blood vessel that carries blood away from the heart to organs in the rest of the body. This research study will look at treating thoracoabdominal or pararenal aneurysm disease with a new device design known as the GORE® EXCLUDER® Thoracoabdominal Branch Endoprosthesis (the ‘Study Device’).The Study Device that will be used to treat the aneurysm is called a “stent-graft”. The Study Device combines a surgical graft material with an outer metal mesh-like form (stent). The nonmetal graft component of the Study Device is made of a soft, polymer material (ePTFE). This material is routinely and safely used for surgical procedures throughout the world today. The graft is surrounded on the outside with a metal frame made from an elastic metal (nitinol wire or stainless steel) bent into a wave pattern and shaped to fit the graft. The materials used in the Study Device are not investigational and have a long, safe history of performance in similar applications.
