Figure 1 Depiction of guide extension catheter-facilitated tip-in technique. (A) The guide extension catheter could advance into the coronary artery to “pick up” the retrograde wire. (B) The guide extension catheter narrowed the lumen which facilitated the entry of retrograde wire into the antegrade microcatheter.
