- Balloon-expandable valves (BEV) showed smaller effective orifice area and higher mean pressure gradient than self-expanding valves (SEV) in women with aortic stenosis.
- After propensity score matching, BEV was associated with lower all-cause mortality and stroke rates at 7 years compared to SEV.
- Heart failure rehospitalization rates were similar between BEV and SEV groups.
- Valve type was not independently associated with long-term outcomes after multivariable adjustment, suggesting both options are acceptable.
- Most female patients (87.6%) had a small aortic annulus, which may influence echocardiographic performance post-transcatheter aortic valve replacement.
