It was reported that stent damage occurred.Vascular access was obtained via the left artery.The 84% stenosed, 3mmx17mm, eccentric, de novo target lesion containing a <=45 degrees bend was located in the mildly tortuous, and severely calcified left anterior descending artery.After a 7f non-boston scientific (bsc) guide catheter, and a 0.14 non-bsc guide wire crossed the lesion, pre-dilation was performed with 3.0x20 emerge balloon catheter resulting to 48% residual stenosis.Following pre-dilation, a 3.00 x 20 synergy drug-eluting stent was advanced for treatment.However, during procedure, it was noted that the stent could not cross the lesion and when removed, the tip of the stent itself was found to be deformed.The procedure was completed with another of the same device.There were no patient complications reported, and the patient's status was stable.
