Why the study?
As TAVI expands to selected low-risk and younger patients with aortic stenosis, outcomes, potential complications, and lifetime valve management require evaluation compared to SAVR.
Does transcatheter aortic valve implantation (TAVI) improve outcomes compared to traditional surgical aortic valve replacement (SAVR) in selected patients at low surgical risk with severe aortic stenosis?
Population
Selected low surgical risk patients with aortic stenosis
Comparison
TAVI vs SAVR
Design
Review of literature from the last 10 years
Key result
TAVI and SAVR provide broadly comparable mid-term outcomes for cardiovascular mortality, stroke, and valve reintervention in low-risk patients, though TAVI has higher pacemaker and regurgitation rates.

Requires heart-team lifetime strategy assessment in low-risk patients; confirms mid-term equivalence but leaves durability and reintervention questions open.
Does transcatheter aortic valve implantation (TAVI) improve outcomes compared to traditional surgical aortic valve replacement (SAVR) in selected patients at low surgical risk with severe aortic stenosis?
TAVI and SAVR offer comparable mid-term outcomes in low-risk severe AS patients, though TAVI carries higher risks of pacemaker implantation and paravalvular regurgitation, necessitating multidisciplinary lifetime management planning.
Wright et al. (2026) conducted a review in severe aortic stenosis. Transcatheter aortic valve implantation (TAVI) vs. surgical aortic valve replacement (SAVR) was evaluated. TAVI and SAVR provide broadly comparable mid-term outcomes for cardiovascular mortality, stroke, and valve reintervention in low-risk patients, though TAVI has higher pacemaker and regurgitation rates.
