  • prospective, investigator-initiated, multicenter study
  • 12 centers

Authors' conclusion

RAP-induced W-AVB demonstrates limited utility in predicting post-TAVR PPI or sudden cardiac death, particularly in patients at high risk for PPI. Clinicians should be cautious when using this test for post-TAVR rhythm management.

Study context

Population
Patients undergoing transcatheter aortic valve replacement (TAVR)included across 12 centers, rapid atrial pacing (RAP) successfully performed post-TAVR in 556
Participants
640 patients
Exposure
RAP-induced Wenckebach atrioventricular block (W-AVB) as a diagnostic test for predicting permanent pacemaker implantation (PPI) or sudden cardiac death within 30 days post-TAVR
  • W-AVBn = 192
Outcome
Sudden cardiac death or guideline-based indications for PPI (Class I and Class II)
Follow-up
Within 30 days post-TAVR
