Right coronary artery was engaged with a 6 Fr AL 1 guiding catheter and left coronary artery was positioned with an 8 Fr JL 4 guiding catheter through the bi-femoral approach. We tried to pass the CTO lesion by anterograde approach using Gaia 2 wire with Crusade¢ç 140cm 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 LAD CTO lesion ( Movie 4). After advancement of Corsair¢ç microcatheter with LCX balloon backup, we performed several balloon dilatations at proximal to middle LAD using Lacrosse balloon 1.0 x 5 mm and Emergy 1.5 x 15 mm (Figure 1). After predilatations, we deployed two Xience Alpine stents (2.75x38mm and 3.5 x 33 mm, middle to proximal LAD, Figure 2, Figure 3) sequentially. The final angiogram showed successful revascularization at LAD CTO lesion ( Movie 5).
