Manufacturer Narrative

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 written by edwards lifesciences, 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 xt 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 16fr esheath is 6.0 mm.The patient¿s access vessel mld was reported to measure 6.1 mm with moderate calcification and tortuosity.In this case, the cause of the iliac artery dissection and resistance inserting the delivery into the esheath cannot be confirmed.However, it is likely that patient factors (borderline access vessel diameter for a 16fr esheath) in combination with vessel calcification and/or tortuosity not appreciated on imaging, could have contributed to the event.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

As reported by our (b)(6) affiliate, a right iliac artery dissection was found upon removal of the 16fr esheath and a patch angioplasty was performed with a prosthetic vessel.The transfemoral tavr procedure was performed via percutaneous access on the right femoral artery.The 22fr dilator was inserted without difficulty.Slight resistance was felt upon insertion of the 16 fr esheath.When a novaflex+ delivery system was inserted, remarkable resistance was noted.A 23 mm sapien xt valve was uneventfully deployed.The delivery system was withdrawn without difficulty.Upon sheath withdrawal, angiography showed a vascular dissection of the right external iliac artery extending to the access site.Ballooning was performed from contralateral approach.As the ballooning was ineffective, a ¿patch angioplasty¿ was performed with a prosthetic vessel.After the treatment, no abnormality was observed on angiography.Per the report, the minimal luminal diameter (mld) of the access vessel measured 6.1 mm with moderate calcification and moderate tortuosity.
