Same case as mdr id as: 2134265-2018-03511 and 2134265-2018-03510.It was reported that vessel dissection and balloon rupture occurred.On an unknown data, approximately 13 years prior to the reported event, a 3.0 x 28 mm taxus liberte paclitaxel-eluting coronary stent was implanted in the left circumflex artery (lcx).Vascular access was obtained via the right femoral and right radial arteries.The 80% stenosed, 3.0 mm x 28 mm,concentric, in-stent restenosis (isr) was located in a moderately tortuous and moderately calcified lcx.There was a significance bend in the lesion between 45 and 90 degrees.A 2.0 x 20 mm emerge balloon catheter was advanced for dilatation followed by a 10/2.50 flextome¿ cutting balloon¿ which failed to cross the lesion.The physician then attempted to use a 2.75 mm x 12 mm nc emerge® balloon catheter to further dilate the lesion but during the second inflation at 14 atmospheres the balloon ruptured and a slight dissection was noted within the taxus liberte stent.The lesion was dilated with a 2.5 x 12 mm nc emerge® balloon catheter and a new 2.75 x 12 mm nc emerge® balloon catheter.However, during the second inflation at 14 atmospheres, the 2.75 x 12 mm balloon also ruptured.A 2.75 x 32 mm synergy drug-eluting stent was successfully deployed and post dilated with a 3.25 x 12 mm nc emerge® balloon catheter.Intravascular ultrasound ( ivus) was used to optimize post percutaneous coronary intervention and no dissection was observed.No further patient complications were reported and the patient's status was stable.
