Reverse flow in BAV patients with isolated AS or AR. Mean systolic and diastolic reverse flow in the AAo as a function of AS severity (a, b) and AR severity (c, d). The covariate for logistic regression is reported with its p-value in each plot. Both AS and AR severity were significantly associated with increasing systolic and diastolic reverse flow. None = no aortic regurgitation or stenosis, Mod = moderate aortic regurgitation (AR) or aortic stenosis (AS), TAV = cohort with trileaflet aortic valve and aortic dilation
