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 had a stroke or stroke symptoms. The purpose of this study is to learn whether a device can help physicians diagnose problems in the brain like stroke more quickly than conventional imaging. Read More

Adults ages 18+.
Being evaluated for suspected stroke.

This study enrolls people with atrial fibrillation undergoing transcatheter aortic valve replacement (TAVR). The purpose of the study is to look at the safety and effectiveness of the WATCHMAN device procedure when it is done at the same time with the TAVR procedure. Read More

Adults ages 18+.
Diagnosed as having atrial fibrillation (AF or AFib) and aortic stenosis (AS) requiring a Transcatheter Aortic Valve Replacement (TAVR).

This study enrolls seniors with severe aortic stenosis. The purpose of this study is to find out whether aortic valve replacement is helpful for patients Read More

-Adults ages 65+.
-Recently diagnosed with severe, calcific, aortic stenosis without any symptoms.

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.

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.

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