Reports come from manufacturers, hospitals and patients and are not verified by the FDA. A report does not prove the device caused the event. Widely used products collect more reports, so totals can't be used to compare products or estimate failure rates. Only reports that name a model's exact device identifier are counted.

  IT WAS REPORTED THAT A PLAIN OLD BALLOON ANGIOPLASTY (POBA) WAS PERFORMED TO TREAT A MODERATELY CALCIFIED AND MILDLY TORTUOUS LESION IN THE LEFT ANTERIOR DESCENDING ARTERY (LAD). AN ASAHI SION BLUE GUIDE WIRE WAS ADVANCED TO THE DISTAL LAD, WHILE A SECOND ASAHI SION BLUE GUIDE WIRE WAS ADVANCED TO THE LEFT CIRCUMFLEX ARTERY (LCX). A 2.5X12MM ONYX STENT (MEDTRONIC) WAS PLACED IN THE OBTUSE MARGINAL BRANCH (OM) AND BALLOON DILATATION WAS PERFORMED. AN ADDITIONAL 3.0X8MM ONYX STENT WAS DEPLOYED TO THE PROXIMAL OM. A 3.5X15MM XIENCE DRUG ELUTING STENT (DES) (ABBOTT) WAS DEPLOYED IN THE LAD, AND BALLOON DILATATION WAS PERFORMED. WHEN AN ATTEMPT WAS MADE TO REMOVE THE TWO SION BLUE GUIDE WIRES SIMULTANEOUSLY IN ORDER TO RE-POSITION THE SUBJECT SION BLUE GUIDE WIRE THAT HAD BEEN ADVANCED IN THE LAD TOWARD THE LCX, THE SUBJECT SION BLUE GUIDE WIRE WAS CAUGHT AND THE WIRE TIP WAS DETACHED. THE GUIDE WIRE WAS REPLACED WITH A DIFFERENT ONE AND RE-POSITIONED IN THE LAD. TWO BALLOON CATHETERS WERE USED FOR DILATATION TO SUCCESSFULLY REOPEN THE STENT. THE FINAL STENT OPTIMIZATION WAS PERFORMED WITH POST-DILATATION WITH AN UNIDENTIFIED BALLOON CATHETER. THE MID LAD LESION WAS NOT TREATED. THE PHY

  IT WAS REPORTED THAT STENT DEPLOYMENT WAS SUCCESSFULLY PERFORMED DURING A PERCUTANEOUS CORONARY INTERVENTION (PCI) TO THE MILDLY CALCIFIED AND 90-99% STENOSED UNSPECIFIED SEGMENT OF THE LEFT ANTERIOR DESCENDING ARTERY (LAD). WHEN AN SECOND ASAHI SION BLUE GUIDE WIRE WAS ADVANCED TO MONITOR WITH THE INTRAVASCULAR ULTRASOUND SYSTEM (IVUS), THE SION BLUE GUIDE WIRE WAS CAUGHT IN THE FIRST DIAGONAL BRANCH (D1). A MICROCATHETER AND BALLOONS WERE PLACED TO REMOVE THE GUIDE WIRE, WITHOUT SUCCESS. THE STUCK SION BLUE GUIDE WIRE CAME OUT, LEAVING THE COATING AND TIP SEGMENT IN THE PATIENT ANATOMY. THE THIRD SUBJECT SION BLUE GUIDE WIRE WAS ADVANCED TO STENT THE WIRE FRAGMENT BUT PERFORATED IN THE D1, CAUSING CARDIAC TAMPONADE. PERICARDIAL DRAINAGE WAS PERFORMED, AND A BALLOON WAS DILATED OVER THE PERFORATION SITE. THE PATIENT WAS TAKEN TO A DIFFERENT HOSPITAL, WHERE A STENT WAS DEPLOYED OVER THE WIRE FRAGMENT. IT WAS REPORTED THAT THE PATIENT HAS BEEN ALREADY DISCHARGED.

  IT WAS REPORTED THAT A PERCUTANEOUS CORONARY INTERVENTION (PCI) WAS PERFORMED TO TREAT A HEAVILY CALCIFIED AND MODERATELY TORTUOUS 90-99% STENOSED TRIPLE VESSEL DISEASE. THE LEFT ANTERIOR DESCENDING ARTERY (LAD) WAS WIRED WITH AN ASAHI SION BLUE GUIDE WIRE AND THE HEAVILY CALCIFIED LESION IN THE LEFT CIRCUMFLEX ARTERY (LCX) WAS WIRED WITH AN ASAHI SUOH 03 GUIDE WIRE. THE LCX WAS PRE-DILATED WITH AN ORBUSNEICH SAPPHIRE BALLOON CATHETER (0.8 MM), AN UNSPECIFIED NON-COMPLIANT BALLOON (2.5 MM) AND THEN A SPECTRANETICS ANGIOSCULPT BALLOON CATHETER (2.5 MM). THE LAD WAS PRE-DILATED WITH AN UNSPECIFIED NON-COMPLIANT BALLOON (3.0 MM) AND AN ANGIOSCULPT BALLOON CATHETER (3.0 MM). TWO OVERLAPPING STENTS WERE THEN DEPLOYED FROM THE MID LAD BACK TO THE LEFT MAIN STEM (LMS), AND MODIFIED T STENTING WAS PERFORMED TO THE LCX. TWO OVERLAPPING STENTS WERE ALSO DEPLOYED FROM THE DISTAL LCX TO THE OSTIUM WITH KISSING BALLOON TECHNIQUE USING TWO UNSPECIFIED BALLOON CATHETERS (3.0 MM AND 3.5 MM) AND PROXIMAL OPTIMIZATION TECHNIQUE USING AN UNSPECIFIED NON-COMPLIANT BALLOON (5 MM) TO THE LMS.

  IT WAS REPORTED THAT TWO ASAHI SION BLUE GUIDE WIRES WERE USED DURING A PERCUTANEOUS CORONARY INTERVENTION (PCI) FOR A MODERATELY CALCIFIED 75% OR LESS STENOSIS FROM THE LEFT MAIN TRUNK TO THE LEFT ANTERIOR DESCENDING ARTERY (LAD). ONE SION BLUE GUIDE WIRE WAS INSERTED INTO THE LAD AND THE OTHER SION BLUE GUIDE WIRE WAS INSERTED INTO THE LCX. THERE WAS A DISSECTION IN THE OSTIAL LAD AND THE GUIDE WIRE WAS UNCOILED AND FRACTURED. THE WIRE FRAGMENT EXTENDED INTO THE AORTA. LIFELONG DUAL ANTIPLATELET THERAPY WAS CONTINUED. IT WAS INFORMED THAT THE PATIENT HAD NO CONSEQUENCES AND THE BLOOD BLOW WAS FINE AFTER THE PROCEDURE.

  IT WAS REPORTED THAT THE TIP OF AN ASAHI SION BLUE GUIDE WIRE HAD FRACTURED DURING A COMPLEX PERCUTANEOUS CORONARY INTERVENTION (PCI) FOR THE HEAVILY DISEASED AND HEAVILY CALCIFIED LEFT CIRCUMFLEX ARTERY (LCX). THE OSTIAL LEFT ANTERIOR DESCENDING ARTERY (LAD) AND THE OSTIAL LCX WAS CALCIFIED. THE SION BLUE GUIDE WIRE WAS SHAPED AND INSERTED INTO THE PATIENT ANATOMY. IT WAS DIFFICULT TO ADVANCE THE SION BLUE GUIDE WIRE INTO THE LCX DUE TO THE TIGHT CURVATURE OF THE VESSEL. THE PHYSICIAN ADVANCED THE SION BLUE GUIDE WIRE INTO THE RELATIVELY EASILY ACCESSIBLE LAD AND ADJUSTED THE TIP CURVE. WHEN AN ATTEMPT WAS MADE TO DELIVER THE SION BLUE GUIDE WIRE TO THE LCX BY PULLING THE GUIDE WIRE BACK, THE WIRE TIP WAS FRACTURED IN THE LAD. THE LENGTH OF THE WIRE FRAGMENT WAS ESTIMATED AT LESS THAN 2CM AND CLOSE TO 1CM. AN UNSPECIFIED STENT WAS DEPLOYED TO TRAP THE WIRE FRAGMENT. THE PATIENT WAS IN CARDIOGENIC SHOCK, AND DURING SUBSEQUENT REVASCULARIZATION SUFFERED CARDIAC ARREST AND DIED. THE PHYSICIAN COMMENTED THAT THE CARDIAC ARREST WAS NOT RELATED DIRECTLY TO THE WIRE FRACTURE, BUT DUE TO A NON-ASAHI SHOCKWAVE CATHETER.

  IT WAS REPORTED THAT A PLAIN OLD BALLOON ANGIOPLASTY (POBA) WAS PERFORMED TO TREAT A MODERATELY TORTUOUS, MODERATELY CALCIFIED 75-90% STENOSIS IN THE RIGHT CORONARY ARTERY (RCA). AN ASAHISION BLUE GUIDE WIRE WAS DELIVERED TO AN UNSPECIFIED SIDE BRANCH FOR PROTECTION PURPOSE AND A NON-ASAHI STENT WAS DEPLOYED IN THE RCA. THE ANGLE BETWEEN THE RCA AND THE SIDE BRANCH WAS ABOUT 90? AND THE SION BLUE WAS 90? CURVED. DURING REMOVAL OF THE SION BLUE, PART OF THE GUIDE WIRE REMAINED BETWEEN THE VESSEL WALL AND THE STENT. THE REMOVED SION BLUE WAS FOUND FRAYED. AS THE RETAINED WIRE FRAGMENT WAS VERY THIN AND WAS TRAPPED BEHIND THE STENT, THE PHYSICIAN DECIDED TO LEAVE IT IN SITU. THE GUIDE WIRE WAS THEN REPLACED TO RESUME THE PROCEDURE. THE PATIENT WAS REPORTEDLY FINE AFTER THE PROCEDURE.

  IT WAS REPORTED THAT THE PROCEDURE WAS A PERCUTANEOUS CORONARY INTERVENTION (PCI) TO TREAT A 18MM LONG, 75% STENOSIS IN THE PROXIMAL LEFT ANTERIOR DESCENDING ARTERY (LAD). DURING THE PCI, THE DISTAL TIP OF AN ASAHI SION BLUE GUIDE WIRE FRACTURED AND WAS RETAINED IN THE PATIENT, REQUIRING SURGICAL INTERVENTION. THE GUIDE WIRE WAS PARKED IN THE DIAGONAL ARTERY TO PROTECT VESSEL WHILE TREATING THE PROXIMAL LAD, ALLOWING ACCESS TO THE DIAGONAL ARTERY IN THE EVENT THE DIAGONAL ARTERY OCCLUDED DUE TO PLAQUE SHIFT FROM STENT DEPLOYMENT IN THE LAD. AFTER STENT DEPLOYMENT, THE WIRE IN THE DIAGONAL ARTERY WAS REMOVED, BUT THE DISTAL TIP OF THE WIRE FRACTURED DURING THE PROCESS. ALTHOUGH ATTEMPTS WERE MADE TO RETRIEVE IT USING A PERCUTANEOUS TECHNIQUE, THEY WERE UNSUCCESSFUL AND IT REQUIRED SURGICAL REMOVAL. THE PATIENT WAS STABLE AFTER THE PROCEDURE AND DISCHARGED FROM HOSPITAL.
