No X-Ray, no dye: new heart valve procedure could spare patients harmful exposure
NCT ID NCT07453849
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
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.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age ≥18 years. * Severe native aortic regurgitation (AR) confirmed by echocardiography (per guideline-recommended multiparametric assessment). * Indication for intervention, defined as symptomatic severe AR (e.g., NYHA class II-IV) or asymptomatic severe AR with evidence of LV decompensation (e.g., reduced LVEF and/or LV dilation per guideline thresholds). * Deemed appropriate for transfemoral TAVR by a multidisciplinary Heart Team (e.g., elevated/prohibitive surgical risk or other clinical/anatomic factors favoring transcatheter therapy). Exclusion Criteria: * Active infective endocarditis or ongoing systemic infection/sepsis. * Aortic pathology requiring open surgery, such as significant ascending aortic aneurysm/root disease above surgical thresholds, acute aortic syndrome, or other conditions where surgery is mandated. * Annulus/landing-zone dimensions outside device range
