Following the high feasibility of analyses by core laboratory with videodensitometry determined in the ASSESS-REGURGE Registry, this is an early clinical feasibility study of online videodensitometric assessment of aortograms to quantitate aortic regurgitation (AR) in the cath lab, specifically in the setting of transcatheter aortic valve replacement (TAVR)
