Table of pressure loss indices (iPL) used in this study, along with references from which they were derived. *TPGmax and TPGnet denote maximum and net transvalvular pressure gradient, respectively. Q = peak systolic flow rate, AVA = aortic valve area, AA = aortic area at sinotubular junction. Q, AVA and AA were obtained from MRI, echocardiography and computed tomography, respectively
