Erratum to prognostic implication of pulmonary artery pulsatility index before transcatheter aortic valve replacement
Erratum to: Cardiovasc Diagn Ther 2022;12:188-95
This article (1) entitled “Prognostic implication of pulmonary artery pulsatility index before transcatheter aortic valve replacement” (doi: 10.21037/cdt-21-682), unfortunately contains an incorrect table (Table 1). In the original Table 1, the number of each approach type, prevalence of comorbidities, and the number of moderate or greater mitral regurgitation/tricuspid regurgitation were incorrect.

Continuous variables are presented as median [interquartile range]. Categorical variables are presented as numbers [percentages]. *, P<0.05. PAPI, pulmonary artery pulsatility index; eGFR, estimated glomerular filtration ratio; MR, mitral regurgitation; TR, tricuspid regurgitation.
After the update, statistical significance for the two-group comparison in these variables remained unchanged. These updates did not change the other statistics, discussion, and conclusions. All original data were double-checked, and the other results and conclusions remain correct. Corrected Table 1 is presented below.
