SMART Trial
SMall Annuli Randomized To Evolut™ or SAPIEN™*
For small annulus† patients, the SMART Trial data are clear: Evolut™ transcatheter aortic valve replacement (TAVR) delivers superior valve performance‡ versus SAPIEN™* platform with excellent early patient outcomes at 1 year.1
About the trial
Evolving TAVR, together.
The SMART Trial was a prospective, multicenter, randomized controlled trial conducted to understand how valve design differences between the Medtronic self-expandable (SE) Evolut™ platform and Edwards Lifesciences balloon-expandable (BE) SAPIEN™* transcatheter aortic valve replacement system affect treatment of small aortic annulus (≤ 430 mm2) patients with symptomatic, severe native-aortic stenosis.
One year late-breaking data confirm that these contemporary TAVs behave differently in this patient group, providing physicians with crucial insights to tailor treatment decisions according to individual patient needs.

† In patients with small annuli (area ≤ 430 mm2) in all-comers trial, consisting of majority low surgical risk participants (52.1%).
‡ Valve performance as defined as freedom from bioprosthetic valve dysfunction (BVD) at 12 months. BVD is a composite including any of the following: hemodynamic structural valve dysfunction (mean gradient ≥ 20 mmHg), nonstructural valve dysfunction (severe prothesis-patient mismatch or ≥ moderate aortic regurgitation), thrombosis, endocarditis, and aortic valve reintervention.
