Key result
Each increase in RIFLE class of acute kidney injury following tricuspid valve surgery was associated with increased mortality (OR 4.2; 95% CI 3.2-5.4; P<0.001).
Population
951 patients undergoing tricuspid valve (TV) surgery between 2000 and 2007, mean age 67, 60% female.

Postoperative AKI severity signals higher mortality after tricuspid valve surgery; leaves open whether prevention alters outcomes.
Cohort (n=951)
Odds Ratio: 4.2 (95% CI 3.2–5.4)
p-value: p=<0.001
Tricuspid valve surgery is associated with a 30% incidence of postoperative acute kidney injury, which is strongly predictive of early mortality and prolonged hospital stay.
Englberger et al. (2012) conducted a cohort in Tricuspid valve surgery (n=951). Acute kidney injury (AKI) vs. Lower RIFLE class / No AKI was evaluated on Mortality per increase in RIFLE class (OR 4.2, 95% CI 3.2-5.4, p=<0.001). Each increase in RIFLE class of acute kidney injury following tricuspid valve surgery was associated with increased mortality (OR 4.2; 95% CI 3.2-5.4; P<0.001).
