Postprocedural myocardial injury and outcomes following transcatheter aortic valve implantation.

ABSTRACT:

Background

 Transcatheter aortic valve implantation (TAVI) has transformed aortic stenosis treatment, yet some patients still experience complications such as post-procedural myocardial injury (PPMI). However, the prognostic significance of PPMI remains unclear. Therefore, this study aimed to investigated the association between post-TAVI cardiac troponin T (cTnT) levels and all-cause mortality.

Methods

Using Danish nationwide registries (2014-2023), we identified TAVI patients with recorded cTnT measurements before discharge. PPMI was defined as cTnT ≥ 15 times the upper limit of normal (14 ng/L). One-year mortality was analyzed using multivariable Cox regression and results were further elaborated after stratification on sex, age groups, recent PCI (within 3 months), and e
