Statistical analyses

Categorical variables are presented as numbers (percentages), and continuous variables are presented as mean ± standard deviation for normally distributed data or median and interquartile range for non-normally distributed data. To compare creatinine clearance groups (baseline, post imaging, and post-TAVI), we used a general linear model test. We performed a paired sample t-test to compare baseline and post-TAVI creatinine clearance. Differences were considered statistically significant at two-tailed p-values < 0.05. All analyses were performed using SPSS version 25 software (IBM Corp., Armonk, NY, USA).
