TRI-HERO stands for Trans Radial Intervention HEmostasis pROtocol.

The TRI-HERO Challenge is a joined effort of Terumo Interventional Systems and radial experts with a clear objective: support best practice sharing to achieve patent hemostasis and preserve radial access. 

You can either join as a PARTICIPANT or as AUDIENCE:

Make sure to complete your submission before September 30


  • Radial access has become standard practice in cardiology1,2 and is rising as a safe access with improved clinical outcome for endovascular interventions3
  • Radial Artery Occlusion (RAO) remains the most frequent post procedural complication of radial access, despite the existence of recommendations to prevent periprocedural RAO4
  • Achieving non occlusive or patent hemostasis is one of the key measures to prevent RAO4.
  • Keeping the radial artery open is crucial to preserve radial access for future interventions.


SUBMIT your protocol

  • Inspire others to improve their practices.
  • Try to win a prize.

VOTE for your favourite protocol

  • Learn from your peers.
  • Elect the best protocol.

PARTICIPATE to the webinars

  • Learn from radial experts, both interventional cardiologists & nurses.
  • Discover the Challenge's rules & objectives.

SHARE with your peers

  • Increase awareness of patent hemostasis.
  • Help preserving radial access.
