It was reported that the patient presented with a non-st-elevation myocardial infarction and the procedure was to treat a lesion in the right coronary artery (rca) with moderate to severe calcification.An intravascular lithotripsy (ivl) catheter was used for calcium modification, however, a dissection occurred in the mid rca.The 4.5x15mm nc trek neo balloon dilatation catheter (bdc) was used without issues and then a 4.0x33mm xience skypoint stent delivery system (sds) was used to treat the dissection.Another 2 nc trek neo balloons, 4.5x12mm and 4.5x15mm, were used without issues and a 4.5x15mm xience skypoint stent was implanted successfully in the proximal rca.Another 4.5x12mm nc trek neo balloon was used for post dilatation and inflated to 30 atmospheres (atms) when a perforation occurred in the mid rca.The physician then used a 4.0x20mm trek balloon as a tamponade then placed a non-abbott covered stent to treat the perforation, however, at that point the patient already expired.Reportedly, the cause of death was the perforation.There was no clinically significant delay in the procedure.No additional information was provided.

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 death and perforation are listed in the xience skypoint 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 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.
