Evolut Low Risk Trial1

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

Sample size

N = 730 TAVR, N = 684 SAVR


Evolut™ R 73%/Evolut™ PRO 23.4%/CoreValve 3.6%

All-cause mortality or disabling stroke

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

CoreValve and Evolut Pooled Analysis: 5-year Incidence of BVD2

CoreValve/Evolut TAVR had significantly better valve performance than surgery as assessed by bioprosthetic valve dysfunction (BVD),* with 3x lower severe PPM in randomized clinical trials at 5 years (3.7% CoreValve/Evolut TAVR versus 11.8% SAVR; p < 0.001).

CoreValve/Evolut TAVR demonstrated significantly lower rates of BVD versus SAVR (7.8% CoreValve/Evolut TAVR versus 14.2% SAVR; p < 0.001). 

Sample size

N = 2,099


CoreValve 88%/Evolut R 12%

Bioprosthetic valve dysfunction out to 5 years

*BVD was defined as3,4: SVD5 (mean gradient ≥ 10 mmHg increase from discharge/30 days AND ≥ 20 mmHg at last echo or new onset/increase of ≥ moderate intraprosthetic aortic regurgitation), NSVD (30-day severe PPM at 30-day/discharge3 or severe PVR through 5 years), clinical valve thrombosis, and endocarditis.

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

Impact of a standardized TAVR technique and care pathway in the Optimize PRO study6

The cusp overlap technique, with an optimized care pathway, demonstrated excellent clinical outcomes in this interim analysis with single-digit pacemaker rates (9.8% PPI at 30 days), low rates of PVL (0% moderate/severe at discharge), and one-day median discharge from main cohort.

Sample size

N = 400 patients in the main cohort. At the conclusion of the study, more than 650 patients will have been evaluated.

PVL (main cohort)

One patient with mild-moderate PVL.

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

SURTAVI 5-year Trial7

Compared to SAVR at 5 years, CoreValve/Evolut TAVR demonstrated no statistical difference in all-cause mortality (30.0% TAVR versus 30.8% SAVR; p = 0.85), numerically lower disabling stroke (4.1% TAVR versus 5.8% SAVR; p = 0.12), and statistically better hemodynamics with stable low gradients in intermediate-risk patients.

Sample size

N = 864 TAVR, N = 796 SAVR
