We engaged the RCA with the 8Fr AL1 guide catheter.  After administering heparin to a goal ACT of >250s, we advanced a sionblue coronary wire to the distal PLV using a Mamba flex microcatheter later swapped for a rotafloppy. We performed rotational arthrectomy was performed using a 1.5 mm Burr at 180K RPM with IV aminophylline. Later the rota floppy was replaced with a wiggle wire again. The vessel was prepared with multiple high pressure balloon inflations with a 3X20 NC balloon throughout the diffusely diseased vessel. The PDA was protected for a provisional one stent strategy. Afterwards using IVUS multiple DES were deployed in the RCA. The ostium of the RCA was dissected due to the guide catheter as demonstrated on IVUS. We placed a 4X38 Synergy at 14 atm in the ostium of the RCA that was placed inside the guide catheter extension.(Video 3)  Later the stent balloon shaft fractured while removing the stent balloon. The plan was to get contralateral access and wire the dissected ostial vessel. Later removed the 8Fr system with a balloon anchor in the 8Fr guide and later snare the stent fragments using large one snare(35X120)(Video 4). Later a 3.5X32 Synergy megatron was placed in the ostium of the RCA at 16 atm later was post dilated with 5.0X12 NC balloon at 20 atm with an excellent result.
