It was reported that during an angioplasty, the 14 fr performer mullins guiding sheath was used to introduce an 8 fr balloon valve and to place a stent; introduction of the balloon occurred without issues.The patient's lesion was located in the pulmonary artery and the course was tortuous.The physician was able to advance the balloon, but was unable to remove the balloon from the sheath after dilation of the artery, and had to remove the entire system from the patient's anatomy.The sheath was observed to have several folds that prevented the angioplasty from being completed.As a result of the sheath folds/ kinking, the physician was required to re-schedule the stent implantation.According to the initial reporter, the patient did not experience any adverse effects due to this occurrence.Additional information regarding event details and patient anatomy has been requested, but is not available at this time.
