No X-Ray, no dye: new heart valve procedure could spare patients harmful exposure

This study tests a new way to replace the aortic valve in people with a leaky heart valve (aortic regurgitation) without using X-rays or contrast dye. Instead, doctors will rely on ultrasound (TEE) to guide the procedure. The goal is to see if this approach is safe and effective, potentially reducing risks like kidney damage and radiation exposure. The study plans to enroll 30 adults with severe aortic regurgitation who are at high risk for surgery.
