Retrograde RCA recanalization process. A: Tip injection showed distal CTO at bifurcation (white arrow). B: Antegrade wire (white arrow) and retrograde wire (yellow arrow) knuckled into middle part and overlapped. C: Reverse CART in RCA CTO (white arrow). D: Guidezilla catheter (white arrow) pick-up retrograde wire and corsair. E: TIMI 3 grade flood in RCA after stents. F: LAD without injury. TIMI: Thrombolysis In Myocardial Infarction
