	OR (95% CI)	p value
Pre-procedural prediction model
Prior RBBB	9.36 (3.09, 29.23)	< 0.001**
Pre-procedural AVA, per 0.1 cm²	1.17 (1.00, 1.37)	0.042*
Post-procedural prediction model
Prior RBBB	10.46 (3.40, 33.29)	< 0.001***
Pre-procedural AVA, per 0.1 cm²	1.41 (1.12, 1.79)	0.004**
AVA ratio	1.72 (1.00, 2.91)	0.043*

The multivariate regression models were obtained via forward and backward variable selection for the pre- and post-procedural prediction models (see “Methods”)
AVA ratio, ratio of post-procedural aortic valve area to pre-procedural area; AVA–PNA ratio, ratio of post-procedural aortic valve area to prosthetic nominal area; CI, confidence interval; OR, odds ratio; other abbreviations as in Table 1
