The device was not returned for evaluation as the stent remains in the patient.
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 perforation, angina, death, pericardial effusion and hypotension are listed in the xience sierra everolimus eluting coronary stent systems instructions for use 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 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 graftmaster device referenced is being filed under a separate medwatch report number.

This is filed on the first xience stent deployed.
It was reported that the xience 3.
0x38 was deployed first in the mid right coronary artery (rca) and overlapped the 4.
0x18 xience that was implanted in the proximal rca second.
A 4.
0 nc (non-compliant) bdc (balloon dilatation catheter) was used to post dilate and then a 4.
0x15 nc bdc at 18 atmospheres.
Patient then had chest pain and a perforation in the mid rca was noted, likely from post dilatation.
The 3.
5x19 mm graftmaster stent was inserted to treat the perforation, but it was unable to cross through the stents due to the tortuosity.
The patient went into cardiac arrest as she became hypotensive and bradycardic.
Cardiopulmonary resuscitation (cpr) was performed with administration of epinephrine, atropine, bicarbonate.
Transthoracic echocardiogram showed a large pericardial effusion.
Pericardiocentesis drained 1.
1 liters of blood.
The graftmaster was attempted again with another guide wire, but it was still unable to cross.
Cpr was discontinued after a long time of performing it and in view of unlikely recovery.
The patient expired.
No additional information was provided.
