Antibiotic Prophylaxis for TAVI: Is Adding a beta-lactam effective?

Official title: The Per-procedural Antibiotic Prophylaxis in Patients Undergoing Transcatheter Aortic Valve Implantation Trial

Run by Copenhagen University Hospital, Rigshospitalet · NCT07442357 · Data updated 2026-11-12

This trial tests whether adding a beta-lactam that covers Enterococcus faecalis to the usual cephalosporin prophylaxis during TAVI reduces bacterial infection or death within 6 months.

What this trial studies

The PAPPI trial is a prospective, cluster-randomized, crossover study conducted across Danish TAVI centers to compare two antibiotic prophylaxis strategies given as a single pre-procedural dose. One group receives cephalosporin alone, while the other receives cephalosporin plus a beta-lactam antibiotic targeting Enterococcus faecalis. The primary outcome is a composite of bacteremia (excluding Enterobacterales) or death within six months after the TAVI procedure; secondary analyses consider each component separately and other clinical outcomes. All patients undergoing TAVI at participating centers are eligible, with follow-up through six months post-procedure. The study is unblinded and includes all Danish centers performing TAVI, with results used to guide prophylaxis recommendations.

Why it matters

Potential benefit: If successful, the study could reduce post-procedural infections and death by optimizing antibiotic prophylaxis around TAVI.

How similar studies have gone: Previous trials in similar prophylaxis strategies have shown mixed results; this study tests a specific combination in a real-world, multicenter setting.
