It was reported that during treatment of a heavily tortuous and heavily calcified right coronary artery with 100% in-stent restenosis, reportedly, after a non-abbott balloon dilatation catheter (bdc) was unable to cross the stenosis, a rx mini trek 1.20x6mm bdc was advanced and able to cross the stenosis.The rx mini trek 1.20x6mm bdc inflated five times.When the mini trek rx bdc was removed, the guide wire came with it.A guide wire was advanced to the lesion and an attempt was made to cross the lesion with a non-abbott bdc, but it could not cross the lesion.The same rx mini trek 1.20x6mm bdc was advanced for the second time, but became caught up in the anatomy, proximal to the lesion.The rx mini trek 1.20x6mm bdc could not cross the lesion.Another guide wire was inserted and another attempt was made to cross the lesion with the rx mini trek 1.20x6mm bdc, but was unsuccessful.It was believed that the dilatation catheter balloon was not properly rewrapped causing the inability to cross the lesion when advanced in the vessel a second time.A non-abbott 1.0mm bdc was able to cross the lesion and a stent was implanted.There were no reported adverse patient sequelae and no reported significant clinical delay in the procedure.No additional information was provided.
