SMART Trial 2-year results1


The SMall Annuli Randomized To Evolut or SAPIEN Trial, or SMART Trial, is a prospective, multi-center, international, randomized controlled trial comparing the Medtronic self-expandable (SE) Evolut™ system versus Edwards Lifesciences balloon-expandable (BE) SAPIEN™* transcatheter aortic valve implantation (TAVI) system in patients with a small aortic annulus (≤ 430 mm2) and symptomatic severe native aortic stenosis. These results emphasize the importance of valve design and its impact on performance.



Through 2 years, Evolut™ TAVI continued to show superior valve performance in small annulus patients compared to SAPIEN™* TAVI with sustained excellent patient outcomes.1

† Valve performance as defined as freedom from BVD through 24 months. BVD is a composite including any of the following: hemodynamic structural valve dysfunction (mean gradient ≥ 20 mmHg), non-structural valve dysfunction (severe PPM or ≥ moderate aortic regurgitation), thrombosis, endocarditis, and aortic valve reintervention.

‡ In patients with small annuli (area ≤ 430 mm2) in all-comers trial, consisting of majority low surgical risk participants (52.1%).


TAVI risks may include, but are not limited to, death, stroke, damage to the arteries, bleeding, and need for permanent pacemaker.

Evolut™ Low Risk Trial2

Evolut™ TAVI shows excellent outcomes in low-risk patients, with a 26% reduction in hazard for death or disabling stroke at 4 years.

Impact of a standardized TAVI technique and care pathway in the Optimize PRO study3


The cusp overlap technique, with an optimized care pathway, demonstrated excellent clinical outcomes in this analysis with consistently low pacemaker rates (11.1% PPI at 30 days overall, 6.4% PPI with 4-step cusp overlap technique adherence/compliance) and low rates of PVL (0% moderate/severe at discharge).

CoreValve™ and Evolut™ pooled analysis: 5-year incidence of BVD4


CoreValve™/Evolut™ TAVI had significantly better valve performance than surgery as assessed by BVD at 5 years,§ with three times lower severe prosthesis-patient mismatch (PPM) at 30 day/discharge in randomized clinical trials. (3.7% CoreValve™/Evolut™ TAVI versus 12.1% SAVR; p < 0.001).

 

CoreValve™/Evolut™ TAVI demonstrated significantly lower rates of BVD versus SAVR (9.6% CoreValve™/Evolut™ TAVI versus 15.4% SAVR; p < 0.001).

TAVI risks may include, but are not limited to, death, stroke, damage to the arteries, bleeding, and need for permanent pacemaker.


SURTAVI 5-year Trial8

Compared to SAVR at five years, CoreValve™/Evolut™ TAVI demonstrated no statistical difference in all-cause mortality (30.0% TAVI versus 30.8% SAVR; p = 0.85), numerically lower disabling stroke (4.1% TAVI versus 5.8% SAVR; p = 0.12), and statistically better hemodynamics with stable low gradients in intermediate-risk patients.
