Evolut TAVR Exhibits Enhanced Valve Performance in Latest Trials
Evolut TAVR System Shows Strong Performance in Small Annulus Patients
Recent findings from a long-term study highlight the impressive results of the Evolut TAVR™ system, particularly in patients with small aortic annuli. The trials showcased in the largest head-to-head randomized control TAVR trial have demonstrated the superior effectiveness and safety of the Evolut device compared to its primary competitor.
Significant Findings from the SMART Trial
The SMART Trial presents a comprehensive analysis of valve performance over two years for patients suffering from aortic stenosis. This trial not only evaluated clinical outcomes but also examined bioprosthetic valve dysfunction (BVD), underscoring the importance of valve quality in this unique patient population.
Lead investigator Dr. Howard C. Herrmann emphasized that valve performance can significantly impact treatment decisions in patients with small aortic annuli. The two-year data confirmed that Evolut TAVR consistently outperformed SAPIEN™ in reducing BVD, which is linked to less favorable outcomes.
Key Statistical Evidence
According to the trial results, the Evolut TAVR system exhibited:
- Five times lower instances of prosthetic valve thrombosis (p=0.0048)
- Nine times fewer cases of hemodynamic structural valve dysfunction, identified by a mean gradient ? 20mmHg (p<0.001)
These results provide crucial insights for medical professionals, guiding them towards optimizing treatment for their patients.
The Importance of Tailored Valve Selection
Aortic stenosis, a condition affecting a significant portion of the population, often necessitates specific valve selections tailored to the unique anatomy of patients, particularly those with smaller aortic annuli. The research further reveals that up to 40% of global patients could fall into this category. Medtronic’s innovative designs make it possible to offer solutions that can adapt to diverse patient needs effectively.
Global Impact and Continued Research
The trial encompassed a vast network of over 80 international sites, attracting participation from 716 patients, with an impressive 87% being women. This focus on women's health in TAVR significantly reflects a commitment to understanding the varied impacts of heart conditions across demographics.

Frequently Asked Questions
What does the SMART Trial focus on?
The SMART Trial investigates the safety and performance of the Evolut self-expanding TAVR compared to SAPIEN balloon-expandable TAVR in patients with aortic stenosis and small annuli.
How many patients were involved in the SMART Trial?
A total of 716 patients were enrolled in the SMART Trial, with a notable 87% being women, highlighting its commitment to inclusivity in research.
What were the key findings regarding valve dysfunction?
The key findings indicated that the Evolut TAVR system resulted in five times less prosthetic valve thrombosis and nine times less hemodynamic structural valve dysfunction than SAPIEN.
Why is valve performance critical for small annulus patients?
Valve performance is crucial for small annulus patients because inadequate performance can lead to adverse health events, including mortality, if not properly managed.
What is Medtronic's overall mission?
Medtronic's mission is to alleviate pain, restore health, and extend life through innovative healthcare technologies and solutions that meet diverse patient needs across the globe.
