Backup Force of Guiding Catheters for the Right Coronary Artery in Transfemoral and Transradial Interventions

Akiyoshi Miyazawa , MD;

ABSTRACT: Ikari is a new guide catheter for transradial intervention (TRI) that produces stronger back-up force by utilizing an unfavorable angle between the subclavian and brachiocephalic arteries. We report the initial results of the Ikari...
