Myocardial Injury After Transcatheter Aortic Valve Replacement According to VARC-3 Criteria

  • Prospective cohort study
  • consecutive patients

Authors' conclusion

About 1 out of 10 patients undergoing TAVR in the contemporary era had PPMI as defined by recent VARC-3 criteria, and baseline factors like female sex and peripheral artery disease determined an increased risk. PPMI had a negative impact on early and late survival.

Study context

Population
Consecutive patients undergoing transcatheter aortic valve replacement (TAVR) with a new-generation transcatheter heart valve
Participants
1,394 patients
Exposure
PPMI vs no PPMI after TAVR
  • PPMIn = 193
Outcome
Incidence, predictors and clinical impact (mortality) of PPMI per VARC-3
