Carotid artery disorder

This study tests a device that uses sound waves (lithotripsy) to break up calcium buildup in the carotid arteries—the main arteries in the neck—before placing a stent to keep them open. The goal is to see if this approach reduces complications like stroke, heart attack, or death …

This study will follow 5,000 adults with carotid artery disease who receive a treatment called TCAR using the ENROUTE system. The goal is to see how safe and effective the device is in real-world settings, especially for groups not well-studied before. Researchers will track majo…

Carotid endarterectomy removes plaque from the neck artery, and surgeons clamp the artery briefly during the operation. In awake patients, doctors check hand strength and speech to decide if a shunt is needed. This study tests whether a forehead sensor that measures brain oxygen …

This early-phase trial tests whether a fluorescent dye called LUMISIGHT (pegulicianine) can light up inflammation in artery plaques removed during surgery. Inflammation is a key driver of heart attacks, but current imaging can't see it clearly. Researchers will compare the dye to…

This study tests a new 3D ultrasound imaging method to map blood vessels in the heart and brain of people with atherosclerosis who are scheduled for carotid surgery. The goal is to see if this non-invasive, radiation-free technique can detect blockages and incomplete vessel netwo…

This study will create a computer tool to predict which older adults are at high risk for serious problems after heart or blood vessel surgery. It will also test if special programs before and during surgery can help prevent confusion, heart issues, and death. About 1,200 people …

This study looks at a protein called GARP in artery plaques from 200 patients having surgery to clear blocked arteries. The goal is to understand how GARP, which is found on platelets and immune cells, might be involved in the inflammation that causes heart attacks and strokes. N…
