Key result
TAVI has demonstrated non-inferiority to SAVR in intermediate-risk patients, but long-term valve durability and complication patterns must be addressed before expanding to low-risk patients.
Why the study?
Does transcatheter aortic valve implantation improve clinical outcomes compared to surgical aortic valve replacement in patients with severe aortic stenosis at low to intermediate surgical risk?
Population
Patients with severe aortic valve stenosis at low to intermediate surgical risk
Comparison
Transcatheter aortic valve implantation (TAVI) vs Surgical aortic valve replacement (SAVR)

Implication
Durability challenges caution against broad TAVI expansion to low-risk younger patients; leaves open need for extended durability trials.
Structured PICO
Does transcatheter aortic valve implantation improve clinical outcomes compared to surgical aortic valve replacement in patients with severe aortic stenosis at low to intermediate surgical risk?
P
Population
A review of clinical trials and registries evaluating transcatheter aortic valve implantation in patients with severe aortic stenosis at low to intermediate surgical risk.
I
Intervention
Transcatheter aortic valve implantation (TAVI)
C
Comparator
Surgical aortic valve replacement (SAVR)
O
Outcome
Clinical outcomes including mortality, stroke, and valve durability
TAVI is a reasonable alternative to SAVR in intermediate-risk patients, but long-term durability and specific complications must be addressed before expanding to low-risk, younger populations.
Limitations
- Unresolved issue of long-term valve durability
- Increased rates of paravalvular leakage compared to SAVR
- Higher incidence of subclinical leaflet thrombosis after TAVI
- Permanent pacemaker implantation remains a concern, particularly with self-expanding valves
Cite This Study
Voigtländer et al. (2018) conducted a review in Severe aortic valve stenosis. Transcatheter aortic valve implantation (TAVI) vs. Surgical aortic valve replacement (SAVR) was evaluated. TAVI has demonstrated non-inferiority to SAVR in intermediate-risk patients, but long-term valve durability and complication patterns must be addressed before expanding to low-risk patients.
