Addition of Albumin to Traditional Risk Score Improved Prediction of Mortality in Individuals Undergoing Transcatheter Aortic Valve Replacement

The authors analyzed their prospective hospital TAVR register to assess whether the addition of serum albumin as a marker of frailty would improve the ability of the STS and EuroSCORE-2 scores to predict mortality.  TAVR patients were divided into 4 groups based on median serum albumin and median STS and EuroSCORE-2 values. 
Result:  A model including albumin in addition to either conventional score improved the prediction of mortality with either score by more than 40%.  
Conclusion:  Using scores that include serum albumin as a marker of frailty can improve the prediction of mortality in patients undergoing TAVR.
