TENDERA is a multicenter randomized controlled trial to compare traditional entry point in the radial artery for TRI and distal puncture at the anatomical snuffbox area for transradial Interventions. The Investigators hypothesized that novel entry point in radial artery may lessen vascular access site complication rate and especially the radial artery late occlusion rate.

the forearm access will be made using traditional technique what was well described previously in the literature. The novel puncture site is located in the snuffbox area distal to the traditional radial access point. Thanks to surrounded anatomical conditions in anatomical snuffbox area vascular access site complications may be lessened comparing to forearm radial access site.

Inclusion Criteria:

IPD may be requested by interventional cardiologists or radiologists IPD information may be shared after a request from individual or academic organizations if some concern and questions will raised

Outcome assessor is blinded regarding used access site (traditional radial or Snuffbox approach)
