It was reported that stent damage post deployment and thrombosis occurred.The target lesion was located in the left anterior descending (lad) artery.After implanting a 2.5x38 promus element dug-eluting stent (des) in the distal lad, a 2.75x24 mm promus element ¿ des was advanced and successfully deployed in mid lad.During post-dilation, angiography revealed a proximal edge deformation on the 2.75x24 mm promus element ¿ des.Deformation was treated by another post-dilation; however, haziness was observed at the proximal edge.A 3.5x20 mm promus element des was then deployed overlapping the 2.75x24 mm stent and completed the procedure.No further patient complications were reported and the patient's status was stable.
