A non-randomized pilot study by Grube et al. (JACC Interventions 2011) has recently shown that TAVI without BAV is feasible and safe, since self-expanding THV are able to "dilate" the stenosed aortic valve through the radial forces of the self-expanding nitinol frame, in which the prosthesis is mounted. According to the mentioned study, omitting BAV allows the delivery of the THV in a controlled fashion without hemodynamic compromise of the patient.
