Infective Endocarditis Following Transcatheter Aortic Valve Replacement
Why the study?
No data exist about the characteristics of infective endocarditis post-TAVR according to transcatheter valve type.
Does valve type (BEV vs SEV) affect the clinical characteristics and outcomes of infective endocarditis post-TAVR?
Population
245 patients with IE post-TAVR
Comparison
Balloon-expandable valve vs self-expanding valve systems
Design
Multicenter registry-based comparative study
Follow-up
Mean 13±12 months

Implication
Valve type may shape IE presentation post-TAVR; supports refined diagnostics but leaves open prospective validation before practice change.
Structured PICO
Does valve type (BEV vs SEV) affect the clinical characteristics and outcomes of infective endocarditis post-TAVR?
P
Population
245 patients with infective endocarditis (IE) post-transcatheter aortic valve replacement (TAVR) from the multicenter Infectious Endocarditis After TAVR International Registry
I
Intervention
Balloon-expandable valve (BEV) system
C
Comparator
Self-expanding valve (SEV) system
O
Outcome
Incidence, clinical characteristics, and outcomes of IE (including microorganism type, vegetation location, embolic complications, and mortality)hard clinical
In patients with infective endocarditis post-TAVR, valve type influences microorganism type, vegetation location, and embolic complications, but not early or late mortality.
