Non-invasive Detection of Right Ventricular Interstitial Fibrosis using MRI in Patients with Pulmonary Hypertension due to Heart Failure with Preserved Ejection Fraction
This study seeks to explore the structural alterations in the right ventricle (RV) of patients with heart failure with preserved ej…
This study seeks to explore the structural alterations in the right ventricle (RV) of patients with heart failure with preserved ejection fraction (HFpEF) by employing cardiac MRI-derived T1 mapping, an indicator of the degree of diffuse fibrosis, that may allow us to answer the following research questions: 1) Does T1 mapping accurately detect diffuse RV fibrosis?; 2) Do pulmonary hypertension (PH) HFpEF patients have increased RV fibrosis compared to controls and/or HFpEF patients without PH?; 3) Does the amount of RV fibrosis correlate with the degree of RV dysfunction?; 4) Does the degree of RV fibrosis vary between various etiologies of PH? Given NMHC's unique and robust HFpEF program and strength in cardiovascular MR research, Northwestern is uniquely suited for this endeavor. The ultimate goal is to provide mechanistic insight into these conditions so that effective, targeted therapies can be developed.

Currently, only about half of all patients with Heart Failure who meet the criteria for an ICD device actually receive one. Also, some patients who receive an ICD device do not benefit from the device but rather incur the increased risks that are associated with the introduction of devices into the body. The purpose of this study is study is to evaluate if an AdreView™ heart function scan can help identify HF patients who may be more or less likely to benefit from having an ICD device implanted. Some research suggests that an ICD device may not be suitable for all patients with mild to moderate HF and a heart blood-pumping efficiency that is between 30% and 35% (ejection fraction 30-35%). An AdreView™ heart function scan could be used to identify people who have a high or low risk of a fatal event in the next 1 to 2 years. This additional information may make it possible to take a more accurate decision about who would and who would not benefit from an ICD device implantation. We expect that participants in the study will be involved for approximately 2¾ to 3 years and will need to come to clinic for study visits 8-9 times, depending upon if an ICD device is received as part of the patient's standard care or not. All participants involved in this study will receive an AdreView™ heart function scan. This heart function scan uses a radioactive imaging drug, AdreView™, which is already approved in the U.S. and Canada for diagnosing other diseases (e.g., cancers). AdreView™ is already approved in the United States by the U.S. Food and Drug Administration (FDA) for imaging the hearts of people with HF. We expect up to 25 people here will be in this research study out of approximately 2200 people in the entire study internationally.
INCLUSION CRITERIA:
• ≥18 years of age
• Females pre-menarchal, surgically sterile, postmenopausal, or negative pregnancy test
• Heart failure NYHA classes II or III for symptoms, ischemic or non-ischemic heart disease, eligible for ICD implantation
• Non-ischemic dilated cardiomyopathy or ischemic heart disease of at least 3 months duration
• 30% ≤ LVEF ≤ 35%
• Clinically stable HF (i.e., no significant changes in medication, no worsening of symptoms, no unscheduled visits to the doctor’s office) for the past 30 days
• Reasonable expectation of meaningful survival for at least 1 year
EXCLUSION CRITERIA:
• Existing ICD or indication of ICD implantation for secondary prevention of SCD
• Hospitalized for HF or for acute coronary syndrome in the previous 40 days

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 research study will evaluate the safety and effectiveness of the Edwards SAPIEN 3 Transcatheter Heart …
This research 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. If you agree to participate in this study, the investigational (experimental) Edwards SAPIEN 3 transcatheter aortic heart valve (study device) and delivery system will be used to replace your failing bioprosthetic aortic valve. The delivery systems are the Commander system (transfemoral access – through the leg) and the Certitude system (transapical and transaortic access through the heart, when a small incision is made in your 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) or any other governmental agency in North America 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 your 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 your heart. If you agree to participate in this research study and pass the screening tests, your involvement will last approximately 10 years. You 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
Inclusion Criteria:
Failing surgical or transcatheter bioprosthetic valve in the aortic position demonstrating ≥ moderate stenosis and/or ≥ moderate insufficiency.
Bioprosthetic valve with an internal orifice diameter of 16 mm to 27 mm.
NYHA Functional Class ≥ II.
Heart Team agrees valve implantation will likely benefit the patient.
The study patient has been informed of the nature of the study, agrees to its provisions and has provided written informed consent as approved by the Institutional Review Board (IRB) of the respective clinical site.

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 has paravalvular regurgitation (includes those instances that have been previously treated with a plug due to paravalvular regurgitation).
Failing valve is unstable, rocking, or not structurally intact.
Increased risk of coronary obstruction by prosthetic leaflets of the failing valve.
Increased risk of embolization of THV (e.g., surgical valve that is non-stented and non-calcified).
Known bioprosthetic valve with residual mean gradient >20 mmHg at the end of the index procedure for implantation of the original valve.

This study is recruiting people who have Type 2 diabetes mellitus (T2DM) or prediabetes and heart failure (Inability of the heart to pump blood with normal efficiency). The purpose of the study is to find out if a drug called dapagliflozin would be effective in improving the blood tests and symptoms related to heart failure while also treating type 2 diabetes or potentially preventing type 2 diabetes if you have pre-diabetes. To do this, dapagliflozin will be compared with placebo. The placebo will look like dapagliflozin but is inactive. Dapagliflozin lowers glucose (sugar) levels in the blood by blocking the effect of specific molecules (small particles) called sodium-glucose transporters. Under normal circumstances, the sodium-glucose transporters in the kidney prevent glucose in the blood stream from leaving the body through urine. Dapagliflozin inhibits the sodium-glucose transporters and lowers blood glucose by allowing glucose removal through the urine. Dapagliflozin may also mildly decrease body weight and lower blood pressure in certain patients. Dapagliflozin is approved by the United States Food and Drug Administration (FDA) for the treatment of type 2 diabetes. Dapagliflozin is not specifically approved for the treatment of type 2 diabetes in people with heart failure and therefore its use in this study is investigational. We expect up to 20 people here will be in this research study out of 320 people in the entire study nationally..
Inclusion Criteria:

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.
Inclusion Criteria:
Severe aortic stenosis
Patient is asymptomatic
The study patient has been informed of the nature of the study, agrees to its provisions and has provided written informed consent as approved by the institutional review board of the respective clinical site.

Exclusion Criteria:
Patient is symptomatic.
Ilio-femoral vessel characteristics that would preclude safe placement of the introducer sheath.
Evidence of an acute myocardial infarction ≤ 1 month (30 days) before randomization.
Aortic valve is a unicuspid, bicuspid, or is non-calcified.
Severe aortic regurgitation (>3+).
Severe mitral regurgitation (>3+) or ≥ moderate mitral stenosis.

This study is recruiting patients who have a condition called “nonvalvular atrial fibrillation.” Normally, electrical signals from the upper chambers of the heart (atria) travel to the lower chambers of the heart (ventricles) and cause them to beat in a regular way. During atrial fibrillation, the electrical signals in your heart are not normal and cause the upper chambers of the heart to beat too fast and irregularly. This irregular beating of the heart leads to a slowing of the blood flow in the upper chambers of the heart. In the left upper chamber, there is a small pouch called the left atrial appendage (LAA). Slowing of blood, especially in the LAA, may cause blood clots to form. Blood clots can move from the LAA and travel to the brain, causing a stroke or transient ischemic attack (TIA), also called a mini-stroke. These blood clots can also travel to other parts of the body and block blood vessels. The purpose of the AMPLATZER Amulet Left Atrial Appendage (LAA) Occluder Trial is to find out if the investigational (not yet approved by the FDA for use in the US) Amulet device is safe and effective when compared to an FDA-approved device called the WATCHMAN LAA closure device. We expect up to 25 people here will be in this research study out of 1700 people in the entire study internationally. Participants will be involved in this research study for up to 5 years. After the procedure, participants will be asked to come to clinic for 5 in-person study visits, and will be contacted via telephone by the study team 5 times.

The objective of this Post Approval Study is to demonstrate that data collected related to the use of the CardioMEMS HF System in a commercial setting are comparable with data collected in a controlled clinical trial. The CardioMEMS HF System provides a method to measure pulmonary artery (PA) pressures by using a small wireless sensor (about the size of a paperclip) implanted into the pulmonary artery (a vessel close to your heart). Once implanted, the sensor communicates through radio frequency to an antenna contained in a pillow connected to an electronic unit and then transmits this valuable information to a secure website for your doctor to review. You will be able to take these PA pressure measurements yourself at home. In addition to these home readings, your PA pressures can also be obtained in the physician’s office, clinic, or hospital. Your doctor can access the secure website to view your measurements allowing him/her to make earlier treatment changes (usually changes in medications) to manage your heart failure remotely. The CardioMEMS HF System was approved by the US Food and Drug Administration (FDA) for commercial use, and is not considered experimental. We expect up to 180 people here will be in this research study out of 1200 people in the entire study nationally. If you agree to participate, we expect that you will be in this research study for two (2) years
Inclusion Criteria:
Diagnosis of NYHA class III heart failure
At least 1 heart failure hospitalization within previous 12 months
Patients with reduced LVEF heart failure should be receiving a beta blocker for 3 months and an ACE-I or ARB for one month unless in the investigator's opinion, the patient is intolerant to beta blockers, ACE-I or ARB
BMI ≤ 35. Patients with BMI >35 will require their chest circumference to be measured at the axillary level. If > 65 inches the patient will not be eligible for the study.
Pulmonary artery branch diameter ≥ 7mm - (implant target artery - assessed during the right heart catheterization)

Exclusion Criteria:
Active infection
History of recurrent (> 1) pulmonary embolism or deep vein thrombosis
Inability to tolerate a right heart catheterization

The purpose of this study is to evaluate the safety and effectiveness of an investigational device for heart failure symptoms. Investigational means it has not been approved by the USA Food and Drug Administration (FDA).The device is called the IASD System II, which is an “inter-atrial shunt”. The device is permanently implanted into the heart. It is designed to reduce the pressure in a part of the heart called the left atrium. This is done by creating a small opening between the left atrium and the right atrium of your heart. If it lowers the pressure in your heart at rest or during activity, it may lessen some of the symptoms you have. You have a 50% chance of receiving the device and a 50% chance of being in the control group for 2 years and then you may have the option of receiving the device This study is an FDA approved clinical trial for this device. The FDA will review the safety results and the treatment effect found in this study. If the FDA accepts the research results the FDA can approve the device for sale in the USA. In April 2016, the Study Device received CE Marking, which is an approval that allows it to be sold in the European Union. If you agree to participate in this study, we expect that you will be involved for about five (5) years. Being in this study requires regular doctor visits. There are visits for testing before the procedure. After the procedure, there are visits at 1 month, 3 months, 6 months and 12 months, and then yearly visits until 5 years after the procedure. The study is over when all the subjects have had their last doctor visit. We expect up to 12 people here will be in this research study out of 700 people in the entire study internationally
INCLUSION CRITERIA: 1. Chronic symptomatic heart failure (HF) documented by the following:
a. Symptoms of HF requiring current treatment with diuretics for ≥ 30 days
