Frailty-AVR Score (pre-TAVI prediction)
Patient assessment
Enter pre-procedural measurements to calculate the five-item tally implemented in the original tool.
About this assessment
This page reproduces the five-item tally from the original Appcardio file: age, serum albumin, BMI, Katz ADL category, and Timed Up and Go time. Each criterion contributes one point when its coded threshold is met.
Thresholds currently implemented
| Item | Threshold in original code | Point |
|---|---|---|
| Age | >80 years | 1 |
| Albumin | <3.5 g/dL | 1 |
| BMI | <18.5 kg/m² | 1 |
| Katz ADL | Totally dependent only | 1 |
| Timed Up and Go | >20 seconds | 1 |
These are documented as the original implementation, not endorsed as validated FRAILTY-AVR scoring criteria.
Evidence and limitations
The cited FRAILTY-AVR study compared seven frailty scales in older adults undergoing TAVR or SAVR. It reported the Essential Frailty Toolset (EFT) as the strongest predictor among the scales compared; the EFT includes lower-extremity weakness, cognitive impairment, anemia, and hypoalbuminemia.
The five inputs and thresholds used on this page do not match the EFT described in that study. Therefore, attribution of this particular five-item tally to Afilalo et al. and its risk classification require verification before clinical use.
