Medtronic Evolut™ TAVR system shows durable clinical outcomes and outstanding valve performance at five years in low-risk aortic stenosis patients

Rhea-AI Summary

Medtronic (NYSE: MDT) has announced compelling five-year outcomes from the Evolut Low Risk Trial for its Evolut™ TAVR system. The study, involving 1,414 patients (730 TAVR, 684 surgery), demonstrated that TAVR patients experienced comparable rates of all-cause mortality or disabling stroke (15.5%) versus surgery (16.4%) at five years.

Key findings showed a numerically lower rate of cardiovascular mortality in TAVR patients (7.2%) compared to surgery (9.3%), along with significantly larger effective orifice areas and lower mean gradients. The trial evaluated patients with severe aortic stenosis who had a predicted 30-day mortality risk below 3%.

The results, presented at the American College of Cardiology's Annual Scientific Session & Expo, support Evolut's supra-annular, self-expanding TAVR as a durable and effective alternative to surgery for severe aortic stenosis patients, regardless of surgical risk.

GALWAY, Ireland and CHICAGO, March 30, 2025 /PRNewswire/ -- Medtronic plc (NYSE: MDT), a global leader in healthcare technology, today announced late-breaking data on five-year outcomes from the Evolut Low Risk Trial. Data shows, versus surgery, the Evolut™ transcatheter aortic valve replacement (TAVR) system delivers a numerically lower rate of all-cause mortality or disabling stroke at five years, strong valve performance and durable clinical outcomes. The findings were presented as late-breaking clinical science at the American College of Cardiology's Annual Scientific Session & Expo and simultaneously published in the JACC, the flagship journal of the American College of Cardiology.

The Evolut Low Risk Trial was a randomized, multicenter, international study assessing the safety and efficacy of the Evolut TAVR system versus surgery in low-risk patients. These patients had a predicted 30-day mortality risk <3%, as assessed by a local heart team. 1,414 patients were randomized, with 730 receiving TAVR with either a Medtronic Evolut R, PRO, or CoreValve™ and 684 undergoing surgery.

"Results at five years support Evolut's supra-annular, self-expanding TAVR as a safe, effective, and durable alternative to surgery for patients with severe aortic stenosis, regardless of their surgical risk," said Michael J. Reardon, M.D., Allison Family Distinguished Chair of Cardiovascular Research and professor of cardiothoracic surgery at the Houston Methodist Hospital and principal investigator of the trial. "The lower mortality risk and strong valve performance is meaningful for clinicians in evaluating treatment approaches that prioritize the overall well-being of patients."

Patients with severe aortic stenosis who were treated with either Evolut TAVR or surgery showed comparable rates of all-cause mortality or disabling stroke at 5 years (Evolut TAVR [15.5%] and surgery [16.4%]; p=0.47). Additional findings at five years include:

• Numerically lower rate of cardiovascular mortality (7.2% Evolut TAVR vs. 9.3% surgery; p=0.15)
• Significantly larger effective orifice areas (EOA) and lower mean gradients in the TAVR vs. surgical arms

"At five years, Evolut has demonstrated lasting clinical outcomes comparable to surgery and a trend toward reduced cardiovascular mortality," said Kendra J. Grubb, M.D., M.H.A., M.Sc., vice president and chief medical officer of Structural Heart, which is part of the Medtronic Cardiovascular Portfolio. "These results reinforce the recently reported Evolut evidence from the SMART trial,[1] which emphasized superior hemodynamics and lower rates of valve dysfunction. The Evolut Low Risk data presented today will help clinicians make personalized treatment decisions for younger, lower-risk patients by considering each patient's unique needs, now acknowledging that data supports TAVR with Evolut as a safe and durable alternative to surgery."
