Predictive factors of early mortality after transcatheter aortic valve implantation: individual risk assessment using a simple score
Why the study?
What are the predictive factors of early mortality after TAVI, and can a simple risk score be developed?
Population
3833 consecutive patients undergoing transcatheter aortic valve implantation for symptomatic aortic stenosis
Design
Cohort
Follow-up
30 days or in-hospital

Implication
Modest validation performance cautions against routine TAVI risk stratification; leaves open need for refined models with better discrimination.
Structured PICO

P
Population
3833 consecutive patients undergoing transcatheter aortic valve implantation (TAVI) for symptomatic aortic stenosis
I
Intervention
Transcatheter aortic valve implantation (TAVI) using Edwards Sapien or Medtronic Corevalve
O
Outcome
30-day or in-hospital mortalityhard clinical
A simple 21-point risk score based on age, symptoms, comorbidities, and approach can predict early mortality after TAVI, though its moderate discrimination limits clinical utility for high-risk identification.
Limitations
- Moderate discrimination is a limitation for the accurate identification of high-risk patients.
