    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 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. 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 16FR ESHEATH IS 6MM. THE MINIMUM LUMINAL DIAMETER FOR THE ACCESS VESSEL IN THIS CASE WAS 6.75X5.35MM; THE VESSEL WAS MODERATELY CALCIFIED AND MILDLY TORTUOUS. THE CASE PHYSICIAN FELT THAT CALCIUM AT THE INSERTION SITE CONTRIBUTED TO THE VESSEL DISSECTION. THE SMALL VESSEL DIAMETER MAY HAVE ALSO BEEN A CONTRIBUTING FACTOR. 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.

    Description of Event or Problem · 1

    DURING A TRANSFEMORAL TAVR PROCEDURE, THE LEFT EXTERNAL ILIAC ARTERY WAS DISSECTED. A VASCULAR SURGEON CALLED IN TO REPAIR THE LOCAL DISSECTION AND THE TAVR PROCEDURE WAS ABORTED. INITIALLY ACCESS WAS OBTAINED AT THE LEFT COMMON FEMORAL ARTERY VIA CUTDOWN APPROACH. EXTRA SUPPORT WIRE USED TO ADVANCE THE DILATORS. THE 16FR DILATOR ADVANCED WITHOUT INCIDENT. THE 16FR SHEATH WAS ATTEMPTED BUT WOULD NOT ADVANCE. NEXT, THE 18FR DILATOR WAS ATTEMPTED BUT WOULD NOT ADVANCE. RUNOFF IMAGING SHOWED A LOCAL DEFECT IN THE LEFT COMMON FEMORAL ARTERY. THE PATIENT REMAINED STABLE DURING THE CASE AND RECOVERED APPROPRIATELY POST PROCEDURE. THE DILATORS AND SHEATH WERE WITHOUT DEFECT UPON REMOVAL FROM PACKAGING AND DURING INSPECTION. THE CASE PHYSICIAN FELT THAT CALCIUM AT THE INSERTION SITE CONTRIBUTED TO VESSEL DISSECTION. THE MINIMUM LUMINAL DIAMETER FOR THE ACCESS VESSEL WAS 6.75X5.35MM; THE VESSEL WAS MODERATELY CALCIFIED AND MILDLY TORTUOUS.
