Clinical Evidence Transcatheter Aortic Valve Hemodynamics

Clinical evidence demonstrates industry-leading hemodynamics

The Medtronic transcatheter aortic valve with a self-expanding, supra-annular design delivers industry-leading hemodynamics. See the recently released clinical evidence on our newest generation TAVI device as well as longer-term hemodynamic performance out to 5 years.

EOA Matters

TAVI Hemodynamics - Flat product image file

A large EOA (effective orifce area) reduces the likelihood of PPM (patient-prosthesis mismatch). Choose Evolut™ TAVI for larger EOAs — allowing patients to maintain a higher exercise capacity.1,2

Supra-annular valves have larger EOAs3

  • A large EOA may improve activity tolerance4 which may allow a faster return to activity.1,2,4     
  • A large EOA helps avoid PPM, which correlates to better long-term survival.5
  • A large EOA provides improved flow, less resistance, and better long-term durability.5,6

Evolut TAVI platform has consistent single-digit gradients

For each increase of 1 mm Hg in mean gradient, the relative risk of heart failure recurrence or heart failure-related death is increased by 6%.7

Gradients Matter

Low Gradients

  • Are an indicator of more efficient blood flow12
  • Reduce stress on leaflets12

High gradients

  • Indicate a greater risk of mortality12

High Risk

Corevalve™ U.S. Pivotal high risk trial 5 years follow up randomized trial

At 5-year mark, a significantly better hemodynamic performance was sustained for CoreValve™ TAVI system over SAVR with less structural valve deterioration* than SAVR11,13.
