New imaging study peers inside rare heart valve condition
NCT ID NCT04645862
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will follow 60 adults with a bicuspid aortic valve (a heart valve with two flaps instead of three) for five years. Each year, participants will get a special 4D CT scan to take detailed measurements of the valve's shape and movement. The goal is to learn more about how the valve works over time, which may help doctors better predict future heart problems.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * At least 18 years of age * Documented bicuspid aortic valve identified via clinical imaging (e.g., CT, MRI, or echocardiogram) with minimal calcification at the time of enrollment * Participant must sign the informed consent form Exclusion Criteria: * Pregnancy (determined by point of care urine pregnancy test) * Renal failure (estimated Glomerular Filtration Rate (eGFR) \< 30), precluding them from receiving intravenous contrast) * Documentation of previous intravenous contrast allergy (unless they are having a CT with steroid preparation as part of routine clinical care) * Previous aortic valve replacement
