It was reported that the procedure was to treat a de novo lesion located in the proximal posterior lateral coronary artery that was mildly tortuous, mildly calcified and 80% stenosed.The nc trek 2.5 x 15 mm balloon dilatation catheter (bdc) was advanced in the anatomy with resistance and inflated to 10 atmospheres but the balloon could not expand further.When the bdc was removed from the anatomy, the balloon tip was kinked and the balloon was ruptured.Another non-abbott balloon was used to successfully pre-dilate the lesion and complete the procedure.It was confirmed that the device was prepped per the instructions for use with no leak noted during preparation.There were no adverse patient effects or clinically significant delay.No additional information was provided.
