    MANUFACTURERS REF# (B)(4). AFTER INVESTIGATION THE EVENT FOR (B)(4) IS NO LONGER REPORTABLE. SUMMARY OF INVESTIGATIONAL FINDINGS: A 70-YEAR-OLD MALE PATIENT UNDERWENT TEVAR ON (B)(6) 2020 WHERE A ZDEG-PT-32-202-PF AS WELL AS 2 ZDES DEVICES ZDES-36-120 AND ZDES-36-180 WERE IMPLANTED WITHOUT DIFFICULTY. THE DEGREE OF OVERSIZING WAS NOT REPORTED. A MOLDING BALLOON WAS USED FOR ¿COMPRESSION OF FALSE LUMEN¿ DURING THE PROCEDURE. PRIMARY INDICATION FOR IMPLANT WAS AN AORTIC DISSECTION. THE PROXIMAL LOCATION OF THE DISSECTION WAS DISTAL TO THE LEFT SUBCLAVIAN ARTERY AND THE DISTAL LOCATION WAS THE INFRARENAL AORTA. THERE WERE NO REPORTED RE-ENTRY TEARS. DETAILS ON THE PROXIMAL LANDING ZONE WERE NOT REPORTED. THE GRAFT FABRIC DID NOT COVER THE LEFT SUBCLAVIAN ARTERY. THE DEVICE WAS PATENT WITHOUT DEVICE INTEGRITY ISSUES AT THE END OF THE PROCEDURE. CONTINUED FLOW INTO THE FALSE LUMEN WAS REPORTED THROUGH AN UNKNOWN SOURCE. THE PATIENT WAS DISCHARGED ON (B)(6) 2020. ON (B)(6) 2021 (123 DAYS POST-PROCEDURE), THE PATIENT HAD A SECONDARY INTERVENTION TO PLACE A DISTAL EXTENSION (ZTA-P-34-161). THE SECONDARY INTERVENTION WAS MARKED AS NOT SUCCESSFUL DUE TO ¿PERSISTENCE OF A DISTAL ENDOLEAK 1B¿. PER REQUESTED INFORMATION ENDOLEAK REFER TO BLOOD FLOW INTO THE FALSE LUMEN. IT IS REPORTED THAT THE PATIENT REMAINS IN THE STUDY AND NO PLANS FOR FURTHER INTERVENTION HAVE BEEN REPORTED. REVIEW OF DEVICE HISTORY RECORD GAVE NO INDICATION OF THE DEVICE BEING PRODUCED OUTSIDE OF SPECIFICATIONS. A PRE-OPERATIVE AND POST-OPERATIVE CT WERE PROVIDED AND REVIEWED BY AN IMAGING EXPERT. ON PRE-OPERATIVE CT SCAN OF (B)(6) 2020 THE IMAGING REVIEWER FOUND ¿THE CELIAC AND SMA ARE PERFUSED BY THE TRUE LUMEN WITH A RE-ENTRY TEAR AT THE ORIGIN OF THE CELIAC. THE LRA IS PERFUSED BY THE FALSE LUMEN WITH MULTIPLE RE-ENTRY TEARS IN THE ABDOMINAL AORTA. THE RRA IS EXTREMELY DIMINUTIVE WITH ATROPHY OF THE RIGHT KIDNEY.¿ ON 6 WEEKS POST-OPERATIVE CT THE IMAGING REVIEWER FOUND ¿THERE IS RETROGRADE FALSE LUMEN PERFUSION FROM THE DISTAL TA ADJACENT TO THE ZDES STENT (ABOVE THE CELIAC) TO THE MID TA AROUND THE DISTAL ZDEG GRAFT. THERE IS NO FLOW BETWEEN THE DISTAL GRAFT AND INTIMA, SO THIS IS NOT A TRUE ENDOLEAK. THE FALSE LUMEN PERFUSION IS LIKELY FROM RE-ENTRY TEAR(S) ALONG THE ZDES STENT IN THE DISTAL TAA.¿ A QUERY TO THE IMAGING REVIEWER WAS PLACED REQUESTING WHETHER THE RE-ENTRY TEARS ALONG THE FIRST ZDES STENT ARE CAUSED BY/RELATED TO THE STENT OR IF THEY WERE PRESENT BEFORE THE STENT WAS IMPLANTED. THE IMAGING REVIEWER RESPONDED ¿THERE WERE RE-ENTRY TEARS AT THE DISTAL TA PRIOR TO THE IMPLANT, NOTHING TO SUGGEST ANY NEW STENT RELATED TEARS FROM THIS IMAGING¿ . BASED ON THE FINDINGS IN THE IMAGING REVIEW NO ENDOLEAK OR NEW RE-ENTRY TEARS IN RELATION TO THE COMPLAINT DEVICE WERE FOUND AND THEREFORE, THE COMPLAINT IS UNCONFIRMED. IN ADDITION, IT IS NOTED THAT THE PATIENT WAS TREATED WITH AT ZTA DEVICE IN THE SECOND INTERVENTION WHICH IS OFF-LABEL AS DISSECTION IS OUTSIDE THE INTENDED USE FOR ZTA DEVICES. COOK WILL REOPEN THE INVESTIGATION IF FURTHER INFORMATION IS RECEIVED. THIS REPORT IS REQUIRED BY THE FDA UNDER 21CFR PART 803. THIS REPORT IS BASED ON UNCONFIRMED INFORMATION SUBMITTED BY OTHERS. NEITHER THE SUBMISSION OF THIS REPORT NOR ANY STATEMENT MADE IN IT IS INTENDED TO BE AN ADMISSION THAT ANY COOK DEVICE IS DEFECTIVE OR MALFUNCTIONED; THAT A DEATH OR SERIOUS INJURY OCCURRED; OR THAT ANY COOK DEVICE CAUSED OR CONTRIBUTED TO; OR IS LIKELY TO CAUSE OR CONTRIBUTE TO A DEATH OR SERIOUS INJURY IF A MALFUNCTION OCCURRED.
