Blood transfusion	108 (33)	98 (30)	.41
RBC transfusion, units	2.0 (2.0, 4.0)	2.0 (2.0, 4.0)	.99
New-onset renal failure	2 (0.6)	5 (1.5)	.45
Hospital stay, d	6 (5, 9)	7 (5, 11)	.001
In-hospital mortality	6 (1.8)	3 (1.0)	.51
30-d mortality	6 (1.8)	4 (1.2)	.52

P value indicates the difference in the incidence rate between the BAV and TAV groups. Significant P values are in bold type. BAV, Bicuspid aortic valve; TAV, tricuspid aortic valve; RBC, red blood cell.
