However, the impact of aortic distensibility in this evaluation remains unkown. PURPOSE The aim of the study was to evaluate the relation between aortic distensibility and RF valve in bicuspid aortic valve patients. METHODS We enrolled bicuspid aortic valve patients without significant aortic stenosis (maximum velocity
