It was reported that the patient presented with a free perforation in the right coronary artery.The 3.5x16mm graftmaster covered stent was attempted to be advanced; however, failed to cross due to anatomy.A 2.8x19mm graftmaster was advanced and deployed successfully; however, the perforation was larger than expected.A 2.8x16mm graftmaster covered stent was advanced to the perforation; however, during inflation the device would not inflate even at 20 atmospheres.It was noted the graftmaster met resistance with anatomy during advancement.Therefore, an additional graftmasters 3.5x19mm was attempted to be advanced; however, failed to cross due to anatomy.A 2.8x16mm graftmaster was used to successfully complete the procedure and seal the perforation.There was no adverse patient sequela and no clinically significant 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.Additionally, a review of the complaint history identified no similar incidents from this lot.It was reported that the graftmaster was inflated to a maximum pressure of 20 atmospheres (atm).It should be noted in the graftmaster rapid exchange (rx), coronary stent graft system, domestic, instructions for use specifies the rated burst pressure (rbp) is 16 atm and clearly states not to exceed the rbp.It is unknown if the exceeded rated burst pressure contributed to the reported event.A conclusive cause for the reported difficulties could not 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.
