Event Description
|
It was reported that failure to deflate device, device detachment and patient death occurred.A 10mmx3.00mm wolverine coronary cutting balloon was selected for a percutaneous coronary intervention procedure.The area of treatment was located in the proximal circumflex artery.A nc balloon was used to dilate the stenosis within the lesion.The nc balloon did not successfully dilate the stenosed lesion.The 10mmx3.00mm wolverine coronary cutting balloon was then advanced and post dilation it was observed that the balloon did not fully deflate.The 10mmx3.00mm wolverine coronary cutting balloon was then moved forward then backwards.The catheter detached from the balloon.The catheter was removed from the balloon and the balloon remained in the vessel.A buddy wire with a second balloon was used to dilate the vessel and to remove the wolverine but was not successful.A snare was used to retrieve the detached balloon but was not successful.The patient was not stable and patient death occurred.

Manufacturer Narrative

E1: initial reporter phone number - (b)(6).The device was not returned for analysis.Procedural angiographic media was provided to assist in the investigation and was reviewed by a boston scientific medical director.Media review identified that a previously placed stent had been placed and a distal stent strut was lifted.The final review noted the following: this case was a high risk, ivus-guided coronary intervention to treat in-stent restenosis in a previously stented lmt bifurcation.The media reviewed are consistent with cutting balloon entanglement with a previously placed stent as the primary issue.Excessive manipulation while positioning the cutting balloon may have caused hypotube damage or entanglement with the previously placed stent.Hypotube damage may have contributed to incomplete balloon expansion or incomplete evacuation of the inflation media during deflation.The inability to completely deflate the balloon did not appear to trap an expanded balloon in the vessel; however, the incompletely deflated balloon did obstruct blood flow through the vessel.Severe ischemia resulted when the partially deflated balloon obstructed the left coronary artery.Continued effort to remove the stuck wolverine catheter resulted in device separation with an irretrievable device fragment lodged in the lmt bifurcation.Preparation for emergency percutaneous mechanical circulatory support ensued but ultimately the patient did not survive.The cutting balloon may have become entrapped by the lifted stent strut leading to withdrawal difficulty.Severe (global) myocardial ischemia caused by lmt obstruction from the device fragment likely contributed greatly to the fatal outcome.
