| - Procedural step: After supporting intraaortic balloon pump, a 8Fr sheath was inserted into the right femoral artery, and the left coronary ostium was engaged with a 8Fr EBU guiding catheter with 3.5cm curve. A 0.014 inch BMW wire and Choice PT wire were inserted into the LAD and LCX respectively. IVUS catheter could not cross the lesions, and we predilated LAD (Figure 3) and LCX (Figure 4). IVUS findings revealed tough and heavily circumferential calcified plaque in the LM (Figure 5) and LAD (Figure 6). After additional kissing balloon and stenting (Xience 3.0 x 28) at middle LAD, we performed mini-crushing with Xience 3.0 x 28 at LCX and Xience 3.5 x 28 mm at distal LM to LAD. Additional kissing ballooning was performed (Figure 7, Figure 8). Final left angiogram and IVUS showed that the procedure was successful (Figure 9, Figure 10 and Figure 11). |
