NCT07442357

Brief Summary

The study is a prospective, crossover, cluster randomized trial in patients undergoing transcatheter aortic valve implantation (TAVI). The study tests whether cephalosporin plus beta-lactam antibiotic with spectrum for Enterococcus faecalis as per procedural prophylaxis is superior to cephalosporin alone in reducing the composite outcome of bacteremia or death at 6 months post-TAVI.

Outcome Measures

Primary Outcomes (1)

  • Number of patients with a composite outcome of bacteremia or death by 6 months.

    Bacteremia is defined as having positive blood cultures (excluding all enterobacterales) registered in the Danish Microbiological Database at 6 months post-TAVI. Death is defined as being registered as deceased in the Danish Civil Registration System at 6 months post-TAVI.

    6 months post-TAVI

Secondary Outcomes (5)

  • Number of patients who died by 6 months

    6 months post-TAVI

  • Bacteremia assessed by collection of blood cultures.

    6 months post-TAVI

  • Number of patients with acute kidney failure assessed by plasma creatinine levels.

    6 months post-TAVI

  • Length of hospital stay

    From the day of TAVI-procedure until the day of discharge after the TAVI-procedure e.g. days from TAVI-procedure until discharge assessed up to 6 months post-TAVI due to end of follow-up.

  • Days-out-of-hospital from TAVI to 6 months

    6 months post-TAVI
