It was reported that a dissection occurred.Vascular access was obtained via the right femoral artery.The 90% stenosed, 25 x 2.75, concentric, de novo target lesion was located in the mildly calcified left anterior descending artery (lad).Predilatation was performed with a 12 x 2.00 maverick balloon resulting in 50% residual stenosis.A 28 x 2.75 promus elite stent was advanced and deployed in the mid lad.It was noted that the stent balloon was inflated to nominal pressure at 11 atmospheres.Following stent deployment, a proximal edge dissection was noted, and was confirmed by angio and ivus.A 12 x 2.75 promus elite stent was deployed proximally to the to the first stent, overlapping it, and covering the edge dissection.The procedure was completed and the patient was reported to be stable.
