Impact of Pre- and Post-Dilatation on Long-Term Outcomes After Self-Expanding and Balloon-Expandable TAVI.

han SEVs and the use post-dilatation is associated with lower survival, while the use of pre-dilatation did not influence survival; (3) however, in regard to the multivariable analysis, survival was impaired by complex CAD, atrial fibrillation, ICU stay, and higher creatinine, while post-dilatation showed a trend towards increased mortality ( p = 0.06), independent of the transprosthetic gradient; and (4) this study included a large number of TAVI platforms (six platforms in total) and there was no heterogeneity in the survival outcomes, while the Portico and Navitor valves were associated with a higher likelihood of permanent pacemaker implantation.

Other valve platforms (Accurate, Boston, Portico, Evolut, Navitor) did not reach statistical significance for all-cause mortality reduction, although Portico tended toward higher risk ( p = 0.07).
