Per the instructions for use (ifu), cardiovascular injuries such as perforation or dissection of vessels, ventricle, myocardial or valvular structures are known potential risks or adverse events associated with the overall thv procedure and may require intervention.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 the transfemoral passage of the devices.Per the instructions for use (ifu), artery rupture and death are a potential adverse events associated with the transcatheter valve replacement (tvr) procedure and the use of the edwards thv devices.In this case, there was no allegation or indication a product malfunction contributed to this adverse event.The root cause of the event remains indeterminable.A review of edwards lifesciences risk management documentation was performed for this case.The reported event is an anticipated risk of the transcatheter heart valve procedure, additional assessment of this adverse event is not required at this time.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 monthly, and any excursions above the control limits are assessed and documented as part of this monthly review.No corrective or preventative actions are required.
