Right coronary artery was engaged with a 7 Fr AL 1 guiding catheter and left coronary artery was positioned with an 7 Fr XB 3.0 guiding catheter through the bi-femoral approach. We tried to pass the CTO lesion by anterograde approach using Fielder XT-R wire with Corsair¢ç 135cm microcatheter ( Movie 3). Lastly, we tried to pass the CTO lesion by anterograde approach with Gaia 2 wire. And then, we successfully pass wire into RCA CTO lesion ( Movie 4). After advancement of Corsair¢ç microcatheter, we performed several balloon dilatations at proximal to middle RCA using Tazuna 1.25 x 15 mm and ROVL 3.0 x 15 mm ( Movie 5). After predilatation, we changed Gaia 2 wire to Runthrough wire and deployed three Ultimaster stents (3.0x38 mm, 3.5x38mm, 3.5 x28mm distal to proximal RCA, Movie 6) sequentially. After stenting, we inflated Raiden 3 4.0 x 20mm upto 20atm (4.2mm) at proximal RCA and 16atm (4.1mm) at mid RCA ( Movie 7). The final angiogram showed successful revascularization at RCA CTO lesion ( Movie 8).
