As reported, during the procedure the 1st esheath was opened and prepared without difficulty.The operator experienced challenging access with difficulty advancing the esheath.The tip of the esheath was reported to be bent and the operator was unable to safely advance the sheath.The perceived cause of difficulty advancing the sheath was severe tortuosity.The vessel was reported to be perforated with extravasation noted on angiogram.Vascular surgery was consulted.The patient had an episode of hypotension (a drop in systolic bp <70) due to blood loss and received 2 units of packed red blood cells (prbc) and 1-unit of platelets during the vascular repair.The patient tolerated the procedure well and was sent to the cardiovascular intensive care unit in stable condition.At the time of this report, the patient was in good condition and awaiting discharge to a rehab facility.

H2, h3, h6 updated.The returned device was visually inspected, and the following was noted; sheath shaft curvature noted.Sheath liner is partially expanded for approximately 1" from the distal tip, rest of the liner unexpanded.Sheath distal tip is opened as designed with scratches noted.Minor damage to the hdpe noted at about 1.5" and 2" from distal tip.No functional and dimensional testing were able to be performed due to the nature of the complaint.A device history record (dhr) review was performed and did not reveal any manufacturing nonconformance issues that would have contributed to the complaint event.A lot history review was performed and revealed no other complaints related to sheath insertion and suturing inability to introduce sheath and sheath insertion and suturing difficulty introducing sheath the returned device meets specification with no evidence to support a manufacturing/design defect has contributed to the complaint, therefore a manufacturing mitigation review was not required.A complaint history review on confirmed device complaints was performed.Of the root causes identified, the following are potentially applicable to the complaint event: patient factors (tortuosity, calcification).A review of edwards lifesciences risk management documentation was performed for this case.No evidence of product non-conformances or labeling/ifu inadequacies were identified in the evaluation.The following instructions for use and training manuals were reviewed: esheath ifu, device prep manual s3 and commander and procedural training manual s3 and commander.No ifu/training deficiencies were identified.The complaint for sheath insertion and suturing inabilit to introduce sheath was confirmed through evaluation of the returned device.However, no manufacturing nonconformance was identified during evaluation.Reviews of the dhr, lot history, and complaint history did not provide any indication that a manufacturing non-conformance would have contributed to the complaint event.A review of ifu/training materials revealed no deficiencies.Furthermore, no abnormalities were reported during device unpacking or preparation.As reported, they experienced a challenging access with difficulty advancing esheath.The perceived cause of difficulty advancing the sheath was severe tortuosity.Per visual inspection of the returned device, the sheath shaft had some curvature.The sheath distal tip was opened as designed, with scratches along the area.The liner was partially expanded for 1 inch from the distal tip.Lastly, there was some damage to the sheath shaft about 1.5 inches from the distal tip.Per the training manual, push force can vary due to angle of insertion, vessel diameter, tortuosity and degree of calcification.Returned imagery shows tortuous bends and calcification in the patients anatomy.Tortuosity can create sub-optimal angles for the sheath which can increase resistance and difficulty during sheath insertion.Calcification can reduce the vessels luminal diameter, creating a constrained effect on the sheath and further increasing resistance.As such, available information suggests that patient factors (tortuosity, calcification) may have contributed to the reported event.Since no edwards defect, which could have resulted in the complaint, was confirmed, no preventative or corrective actions (capa) are required.Since no product non-conformances or ifu/training deficiencies were identified during evaluation, a product risk assessment (pra) escalation is not required.In this case, the vessel was perforated possibly due to procedural factors (difficulty advancing) and/or challenging access that may have contributed to the complaint event.
