We are enrolling people who are undergoing a cardiac neurological procedure. The purpose of this study is to collect information from a medical device used in these procedures called the VISOR device. We will collect information before and after a person has a cardio-cerebrovascular procedure to see how well the device detects neurological injury from the procedure. Read More

-Adults ages 18+.
-Undergoing cardiovascular procedures including trans-aortic valve replacement (TAVR), left atrial appendage closure, electrophysiological ablation, coronary artery bypass grafting (CABG) and valve replacement surgery, with the application of Cerebrotech VISOR.

This study enrolls infants who have a patent ductus arteriosus or ‘PDA’. The purpose of this study is to compare two care methods to determine which is better for treating premature babies with PDA. Read More

Children (infants) who were born prematurely at 22-28 weeks and 6 days gestational age.
Must have been diagnosed with a PDA (patent ductus arteriosus) and be in the NICU at Oishei Children’s Hospital.

This study enrolls people who have a heart condition called arrhythmia. The purpose of this study is to map the electrical impulses from inside the heart chambers to better understand abnormal pathways. Read More

Adults ages 18+.
People who will need to undergo electrophysiology study for supraventricular arrhythmia, atrial flutter/fibrillation ablation as their standard clinical treatment plan.

This study enrolls people who have recently undergone a Transcatheter Aortic Valve Replacement (TAVR) procedure at Gates Vascular Institute. The purpose of the study is to learn more about the pros and cons of the TAVR procedure. Read More

Adults ages 18+.
People presenting to the TAVR clinic for an initial visit, a 1 month follow up visit or a 1 year follow up visit.

The purpose of this study is to determine if participating in a modified constraint-induced movement therapy program (M-CIMT) through Internet monitoring sessions increases the amount of movement and use of your weak arm after a stroke and improves your ability to attend sessions in the comfort of your home.

• Coronary artery disease (by cardiac catheterization or definite myocardial infarction)
• ICD implantation for the primary prevention of SCA
• Optimal medical therapy for heart failure [angiotensin converting enzyme inhibitor (ACEI) or angiotensin receptor antagonist (ARA)].

We are looking for people who have had a foot wound related to vascular disease AND healthy volunteers for this study. This study is being conducted to see how well a non-invasive imaging technique allows researchers to see blood inside the human body. The technique combines light and sound to create an image. We would like to see how well this imaging technique can show the veins in the foot in 3D. Read More

Healthy Volunteer:
Age 18+
Not pregnant

Wound Patients:
Age 18+
Chronic wound on foot that is related to a vascular disease

This study enrolls adults with tricuspid valve regurgitation. This is a condition where the valve between the two right heart chambers does not close correctly. The purpose of this study is to learn about patients' preferences for managing and treating this condition. The results of the study may help other patients with tricuspid valve disease, as well as healthcare professionals providing care to patients with tricuspid valve disease, in the future. Read More

Adults ages 21+
Diagnosis of tricuspid valve regurgitation (moderate or greater)
Untreated or receiving medical management and still symptomatic

This study enrolls people who have been diagnosed with an ischemic stroke, a type of stroke where an artery in your brain has been blocked by a blood clot. The purpose of this study is to collect information (data) on medical devices used in the procedure to remove the blood clot and look at the success and related to different medical devices. Read More

Adults ages 18+
Diagnosed with ischemic stroke and planning to undergo procedure to remove blood clot

This study enrolls people who have been diagnosed with Tricuspid Regurgitation (TR) and have Heart Failure symptoms which are not under control despite treatment with current available therapies. The purpose of this study is to compare a new investigational (experimental) device plus optimal drug therapy with optimal drug therapy alone. Read More

Adults ages 18+
Diagnosed with moderate or greater Tricuspid Regurgitation/Insufficiency with Heart Failure symptoms
