Combined simulation and ex vivo assessment of free-edge length in bicuspidization repair for congenital aortic valve disease.

Our group previously published a simulation-based assessment on the relationship between leaflet free-edge length and valve performance, showing a clear trend toward stenosis with shorter free-edge length and toward subannular billowing with longer free-edge length. 7 Moreover, ideal flow patterns were observed at a free-edge length to aortic diameter (FELAD) ratio of approximately 1.57, which one can predict from calculating half the aortic circumferenc
