Atherectomy was performed in the left anterior descending (lad) artery, followed by balloon angioplasty.The vessel was heavily calcified throughout.The sapphire balloon was inflated in the proximal to mid lad, distal to the heavily calcified atherectomy treated segment.A dissection was noticed, and flow was diminished.A balloon was advanced, followed by stent placement in the distal end of the lad and covered the distal edge of the dissection area.Multiple attempts were made to advance additional balloons and stents to cover the area between the distal and proximal stents.Following stent deployment, wire access was lost, and the vessel was rewired.Neither non-csi balloons, nor stents were able to advance through the lesion.A sapphire balloon was then advanced through the lesion, the balloon appeared to be within the stent and vessel lumen with no areas of waist observed during the inflation.The balloon burst while being inflated within the distal segment of the lad artery beyond a large diagonal branch, proximal to a newly placed stent.The sapphire balloon was then removed, and other balloons were advanced through the lesion.No stent was able to be advanced through the lesion.The dissection proximal to the most distal stent remained after multiple attempts.Angiography revealed the flow to the lad and diagonal branch to be brisk.The procedure was then completed and the patient was hemodynamically stable.The balloon will be returned.
