An 8F sheath was inserted through right femoral artery, and the left coronary artery was engaged with an 8F JL catheter with 4.0 cm curve. 0.014-inch 180cm Sion wire was inserted into the 1st diagonal branch. 0.014-inch 180cm Sion wire was inserted into the 2nd diagonal branch. And 0.014-inch 180cm Fielder XT wire was inserted into the LAD. Proximal to mid LAD was pre-dilated with 3.0 X 20mm Quantum balloon.(Figure 1) And then, we pre-dilated 1st diagonal branch using 2.0 X 15mm Tazuna balloon.(Figure 2) Thereafter a Xience Alpine 3.0 X 18 mm Stent was successfully deployed at 2nd diagonal branch, firstly.(Figure 3) Another Xience Alpine 2.75 X 18 mm Stent was successfully deployed at 1st diagonal branch.(Figure 4) And then a Xience Alpine 3.25 X 38 mm Stent was successfully deployed at mid to proximal LAD by crushing.(Figure 5) And 0.014-inch 182cm Choice PT wire was inserted into the 2nd diagonal branch. Additional kissing ballooning was performed by using a NC TREK 3.5 X 15mm at proximal LAD and a Quantum 2.75 X 15mm at 2nd diagonal branch.(Figure 6). And then, 0.014-inch 182cm Choice PT wire was reinserted into the 1st diagonal branch. Additional kissing ballooning was performed by using a NC TREK 3.5 X 15mm at proximal LAD and a Quantum 2.75 X 15mm at 1st diagonal branch.(Figure 7). Final left angiogram and IVUS showed that the procedure was successful.( Movie 4, Movie 5)
