It was reported that the procedure was to treat a 90% stenosed lesion in the proximal right coronary artery (prca).The 2.25x28mm xience skypoint drug eluting stent (des) was advanced to the target lesion without issue but the indeflator did not hold pressure and contrast was observed via imaging on the first inflation attempt at 1 atmosphere (atm) indicating a balloon rupture.The contrast leaked and entered the artery, and the patient had a brief episode of chest pain and st changes.The stent remained on the balloon after the rupture and the device was removed without issue.The angina and st changes were treated with morphine and nitrile glycerin, which resolved quickly, after which a non-abbott stent was used to successfully complete the procedure.There was no adverse patient sequela and no clinically significant delay in the procedure.No additional information was provided.

A visual and functional inspection was performed on the returned device.The reported material rupture was confirmed.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no similar incidents from this lot.The reported patient effect of angina is listed in the xience skypoint, everolimus eluting coronary stent system (eecss), electronic instructions for use (eifu) as a known patient effect of coronary stenting procedures.The investigation was unable to determine a conclusive cause for the reported material rupture.A conclusive cause for the reported patient effect, 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.
