Prospective 4D CTA of BAV Competence
University of Pennsylvania
Summary
The study involves annual 4D CTA imaging of the bicuspid aortic valve for a period of 5 years. CTA is often standard of care for BAV patients, but patients in this study will receive a higher radiation dose with a 4D imaging protocol. There may also be patients enrolled in the study who have a 4D CTA for research purposes when a routine CTA is not required for clinical care.
Description
The bicuspid aortic valve (BAV) is the most common congenital heart disease. The purpose of this study is to better understand the anatomy of physiologically normal, or competent, BAVs without stenosis or insufficiency (AI) in order to support evidence-based standardization of BAV repair surgery. Men and women over 18 years of age with a diagnosis of BAV and minimal aortic valve calcification at baseline will undergo annual 4D computed tomography angiography (CTA) scans, routine transthoracic echocardiograms, and history and physical assessments over the course of the 5-year study period.
