Manufacturer Narrative

System updates pending.No results available since no evaluation performed.According to the instructions for use (ifu), cardiovascular complications, including perforation or dissection of vessels which may require intervention, are potential adverse events associated with the transfemoral transcatheter aortic valve replacement procedure.According to literature review, and as documented in a technical summary, vascular complications are a well recognized complication of the transfemoral tavr procedure in this elderly population with multiple co-morbidities.Edwards has reviewed many reports, including screening data records and source documentation of vascular complications and has found that the root cause is typically related to a combination of vessel size, tortuosity and calcifications.Although the incidence is decreasing with smaller sheath/delivery system sizes and physician experience, there will continue to be cases in which vascular complications will occur.The thv physician training manuals instruct on procedural considerations for sheath insertion with regards to proper screening critical to reducing vascular complications.The training manual instructs the operator on proper sheath insertion and withdrawal techniques, including pre-dilating the vessel with the edwards dilators, as needed.It also notes that calcification may reduce lumen diameter and limit or prevent transfemoral passage of the devices.The ifu contraindicates patients with ilio-femoral vessel characteristics that would preclude safe placement of sheaths such as severe obstructive calcification or severe tortuosity.Pre-procedure screening and assessment of the femoral/iliac artery internal diameters will enable the clinician to determine if the sapien valve can be delivered transfemorally.Assessment of location and amount of circumferential calcium will aid in determining areas of reduced vessel diameters.The operators are trained to measure minimum vessel diameter taking calcium into account.The physician training manual also lists the minimum recommended vessel size for each size device.Despite the best screening tools, a small percentage of patients will have femoral/iliac vessels that are not amenable to the trans-femoral approach or where increased resistance is encountered during insertion of devices.In many cases, the vessel minimum luminal diameter (mld) may be borderline or below the indicated size.In addition, significant calcification and/or tortuosity, not always appreciable on imaging, could be contributing factors to the event.The minimum required vessel diameter for a 20fr sheath is 7mm.In this case, the access vessel mld was 7mm.It is possible that a borderline vessel diameter in combination with vessel calcification and/or tortuosity not appreciable on pre-procedural imaging likely caused or contributed to the reported vascular complication.The ifu and training manuals have been reviewed and no inadequacies have been identified with regards to warnings, contraindications, and the directions/conditions for the successful use of the device.Complaint histories for all reported events are reviewed against trending control limits on a monthly basis, and any excursions above the control limits are assessed and documented as part of this monthly review.No corrective or preventative actions are required at this time.

Event Description

During a transfemoral tavr procedure, upon removal of the 20fr esheath, a perforation was noted in the left common femoral artery.A stent was used to repair the perforation.The patient was stable and transported to icu.The event was attributed to the patient's small access vessels.The 20fr e-sheath and dilators advanced with little to no difficulty.The patient's access vessel minimum luminal diameter (mld) measured 7mm.The vessel was moderately calcified and mildly tortuous.
