Right coronary artery was cannulated with a 8 Fr ALJ1 SH guiding catheter and left coronary artery was positioned with 7 Fr JL 3.5 SH guiding catheter through the bi-femoral approach, respectively. Initially, Sion blue¢ç 0.014 inch 180cm guidewire was inserted into LCX. And then by using the Corsair¢ç 0.014 inch 2.6 Fr 150cm microcatheter, Sion blue¢ç 0.014 inch 180cm guidewire was tried into PDA to the septal branch (Figure 1). Finally, we crossed the septal branch with XT-R 0.014 inch 180cm and Ultimate 0.014 inch 180cm (Figure 2). Thereafter retrograde wire was advanced into LAD guiding catheter and ASAHI Corsair ¢ç 0.014 inch 2.8 Fr -150cm Coronary Micro-Guide catheter was advanced into LAD guiding catheter by anchoring with Amadeus 2.5 sized balloon. Retrograde wire was changed into RG3 long wire (330 cm) and externalized into outside of antegrade guiding catheter. And then Crusade ¢ç 0.014 inch 2.6 Fr -135cm Coronary Micro-Guide catheter was advanced into LAD (Figure 3). After several predilation, we deployed 2 consecutive stents with overlapping (RESOLUTE INTEGRITY stent 3.0x24 mm and 3.0x38 mm in LM to mLAD) (Figure 4, Figure 5). Final angiogram showed successful stent expansion without periprocedural complications ( Movie 3, Movie 4). |
