Impact of residual regurgitation after aortic valve replacement
Why the study?
Does residual aortic regurgitation >1/4 reduce survival in patients after isolated standard aortic valve replacement?
Population
3,201 consecutive patients who underwent isolated standard aortic valve replacement between 1992 and 2011.
Comparison
Presence of residual paravalvular leak >1/4. vs Presence of residual paravalvular leak ≤1/4.

Implication
Residual AR >1/4 after AVR was associated with lower survival; leaves open whether minimizing it improves outcomes.

Population
3,201 consecutive patients who underwent isolated standard aortic valve replacement between 1992 and 2011.
I
Intervention
Presence of residual paravalvular leak (aortic regurgitation) >1/4 (n=135, 4.2%).
C
Comparator
Presence of residual paravalvular leak (aortic regurgitation) ≤1/4.
O
Outcome
Survival (postoperative mortality) at 1, 5, and 10 years.hard clinical
Postoperative residual aortic regurgitation >1/4 after standard aortic valve replacement is an independent predictor of long-term mortality.
