It was reported that the procedure was to treat a 95% stenosed de novo lesion in the right coronary artery (rca) with moderate calcification and heavy tortuosity.Following pre-dilatation, the 2.50x48mm xience xpedition stent was implanted and post dilatation was performed with a nc balloon.Later in the day, the patient experienced chest pain and was returned to the cath lab.The patient went into cardiac arrest, could not be revived and expired.Per the physician, the 2.50x48mm xience xpedition stent and stent system did not cause or contribute to the death.No additional information was provided.

The stent remains in the patient.The device was not returned for analysis.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.The reported patient effects of angina and death are listed in the xience xpedition everolimus eluting coronary stent systems instructions for use (ifu) as known patient effects of coronary stenting procedures.A conclusive cause for the reported patient effects, and the relationship to the product, if any, cannot be determined; however, the subsequent treatment appears to be related to the operational context of the procedure.There is no indication of a product quality issue with respect to manufacture, design or labeling.The xience xpedition 48 is currently not commercially available in the us; however, it is similar to a device sold in the us.
