Three days earlier the main procedure to RCA CTO, Xience A 2.75 x 38mm Drug eluting stent (DES) was implanted at proximal to mid LAD ( Movie 4). On the day for main procedure to RCA CTO, 7 Fr sheaths were inserted thorough the left and right femoral artery. Left coronary artery was engaged with a 6 Fr JL 4 diagnostic catheter and RCA was engaged with a 7 Fr guiding catheter. The wire, 0.014-inch 190 BMW was inserted into the RCA through Corsair 2.6Fr micro guide catheter. Pre-dilation performed with a FLUYDO 2.0 x 20 mm balloon ( Movie 5) and Emerge NC 2.5 x 20 mm balloon ( Movie 6). And then Absorb GT1 BVS 3.0 x 28mm, 3.0 x 28mm, and 3.5 x 23mm were deployed at distal to mid part of the RCA ( Movie 7, Movie 8, Movie 9). And Xience A 4.0 x 23mm DES was implanted at proximal part of the RCA ( Movie 10). After stenting, we performed additional balloon angioplasty with Empira NC 3.0 x 20 mm balloon, Raiden3 3.5 x 20mm balloon, and Pantera LEO 4.5 x 8mm balloon ( Movie 11, Movie 12, Movie 13). Final angiogram ( Movie 14) and IVUS ( Movie 15) showed that the procedure was successful.
