Dreyfus et al reported the TRI-SCORE for the prediction of in-hospital mortality for a patient undergoing isolated tricuspid valve surgery. This can help to identify a patient who may benefit from more aggressive management. The authors are from multiple institutions in France and Canada.
Patient selection: isolated tricuspid valve surgery, adult
Parameters:
(1) age in years
(2) NYHA functional class
(3) signs of right-sided heart failure
(4) daily dose of furosemide in mg
(5) glomerular filtration rate in mL per min (GFR)
(6) serum total bilirubin
(7) left ventricular ejection fraction (LVEF) in percent
(8) right ventricular dysfunction
