Comparing imaging methods before heart valve replacement

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate various imaging modalities used for measuring the aortic root prior to transcatheter aortic valve implantation (TAVI) in patients with aortic valve stenosis. It involves both retrospective and prospective data collection, assessing imaging techniques such as CT, MRI, angiography, and echocardiography to determine the best approach for selecting the appropriate valve prosthesis. The imaging will be performed with contrast injections into the aorta or left ventricle, and the results will be analyzed by blinded observers to ensure objectivity.
