We decided to perform intervention at left main lesion firstly, and then treat RCA lesion. A 7 Fr sheath was inserted through right femoral artery, and the left coronary artery was engaged with a 8 Fr JL4 SH guiding catheter. For LM bifurcation lesion, as FFR revealed 0.61 at pLAD and 0.63 at pLCx, we decided to do mini-crush. 0.014-inch 180cm Sion BLUE and Sion guidewire was inserted into the LCX and LAD, respectively. We pre-dilated LM to pLAD and pLCx using 2.5 x 20 mm BH PLUS (Figure 1, Figure 2). An Osiro stent 3.5 x 22 mm was successfully deployed at proximal LCX (Figure 3), firstly and then another Osiro stent 4.0 x 18 mm was deployed at LM to proximal LAD (Figure 4). Additional kissing ballooning was performed by using an Empira NC 3.5 x 15 mm at LM-pLAD and Pantera 3.0 x 15 mm at proximal LCX (Figure 5). We check angiogram and IVUS showed that the procedure was successful. ( Movie 4, Movie 5) And then, we moved on the RCA lesion. 7 Fr AL1 4.0 SH guiding catheter was engaged on RCA. Firstly, the lesion was dilated with BH PLUS 2.5 x 20 mm balloon (Figure 6). Two Osiro stents 3.5 x 40 mm and 3.5 x 13 mm was implanted sequentially (Figure 7). Final angiogram showed that the procedure was successful ( Movie 6, Movie 7).
