Reportable based on device analysis completed on 01-oct-2020.It was reported that crossing difficulties were encountered.Vascular access was obtained via the femoral artery.The 90% stenosed, 15x3.00mm, eccentric, de novo target lesion with a bend of >=90 degrees was located in the severely tortuous and mildly calcified left circumflex artery.After a 6f guide catheter and a non-boston scientific guide wire crossed the lesion, pre-dilation was performed with a balloon catheter resulting to 50% residual stenosis.A 16 x 3.00 promus premier select drug-eluting stent was advanced but failed to cross the lesion even after multiple attempts.The device was removed from the patient's body and the procedure was completed with a different device.No patient complications were reported and the patient's status was stable.However, returned device analysis revealed stent damage.
