Because of supra\u2010annular deformity, device selection for bicuspid AS has not been systemically studied.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Twelve patients with bicuspid AS who underwent TAVR with self\u2010expanding THVs were included in this study. To assess supra\u2010annular structure, sequential balloon aortic valvuloplasty was performed in every 2 mm increments until waist sign occurred with less than mild regurgitation. Procedural results and 30 day follow\u2010up outcomes were analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Seven patients (58.3%) with 18 mm; three patients (25%) with sequential 18 mm, 20 mm; and only two patients (16.7%) with sequential 18 mm, 20 mm, and 22 mm balloon sizing were performed, respectively. According to the results of supra\u2010annular assessment, a smaller device size (91.7%) was selected in all but one patient compared with annulus based sizing strategy, and the outcomes were satisfactory with 100% procedural success. No mortality and 1 minor stroke were observed at 30 d follow\u2010up. The percentage of NYHA III\/IV decreased from 83.3% (9\/12) to 16.7% (2\/12). No new permanent pacemaker implantation and no moderate or severe paravalvular leakage were found.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>A supra\u2010annular
