Why the study?

Does preoperative moderate/severe tricuspid regurgitation impact mortality in patients undergoing TAVR?

Structured PICO

Does preoperative moderate/severe tricuspid regurgitation impact mortality in patients undergoing TAVR?

Population

518 patients undergoing transcatheter aortic valve replacement (TAVR) from January 2007 to August 2012 at St. Paul's Hospital, Vancouver, Canada

Intervention

Preoperative moderate/severe tricuspid regurgitation

Comparator

Preoperative none/mild tricuspid regurgitation

Outcome

2-year all-cause mortalityhard clinical

Preoperative moderate/severe tricuspid regurgitation is present in about 15% of TAVR patients and is associated with increased mortality specifically in those with preserved or mildly reduced LVEF (>40%), though it is not an independent predictor of mortality overall.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Should not yet change TAVR risk assessment; leaves open TR's prognostic role in LVEF >40%.
