A novel clinical prediction rule for 30‐day mortality following balloon aortic valuloplasty: The CRRAC the AV score
Why the study?
Does the CRRAC the AV score better predict 30-day mortality following balloon aortic valvuloplasty compared to the EuroSCORE in patients with severe aortic stenosis?
Population
281 consecutive patients with severe aortic stenosis who underwent balloon aortic valvuloplasty, mean age 83…
Comparison
CRRAC the AV risk score vs Additive and logistic EuroSCORE

Implication
May improve pre-BAV risk stratification in severe AS; hypothesis-generating and requires prospective validation.
Structured PICO
Does the CRRAC the AV score better predict 30-day mortality following balloon aortic valvuloplasty compared to the EuroSCORE in patients with severe aortic stenosis?
P
Population
281 consecutive patients with severe aortic stenosis who underwent balloon aortic valvuloplasty (BAV), mean age 83 ± 9 years, 61% women.
I
Intervention
CRRAC the AV risk score (incorporating critical status, renal dysfunction, right atrial pressure, and cardiac output)
C
Comparator
Additive and logistic EuroSCORE
O
Outcome
30-day mortalityhard clinical
The CRRAC the AV score provides better discrimination for 30-day mortality after balloon aortic valvuloplasty than the EuroSCORE.
Limitations
- Validation needed in other cohorts of post-BAV patients
