Stroke volume index and transvalvular flow rate trajectories in severe aortic stenosis treated with TAVR
Why the study?
Does TAVR impact flow status and does post-TAVR flow rate predict mid-term mortality in all-comers with severe AS?
Population

Overview
Post-TAVR flow rate may refine mortality risk stratification; leaves open whether it should guide management in severe AS.
Structured PICO
Does TAVR impact flow status and does post-TAVR flow rate predict mid-term mortality in all-comers with severe AS?
P
Population
All-comers with severe aortic stenosis (AS)
I
Intervention
Transcatheter aortic valve replacement (TAVR)
O
Outcome
Mid-term all-cause mortalityhard clinical
Post-TAVR flow rate is a better predictor of mid-term mortality than baseline flow status or post-TAVR stroke volume index in patients undergoing TAVR for severe AS.
