The physician treated a patient with multiple medical comorbidities and severely calcified lesions.After atherectomy with a rota wire and 1.5 mm burr, the guidewire was exchanged for a choice pt and the angiosculpt was delivered with not much resistance.The angiosculpt was inflated two times; one at 8 atm (nominal pressure) for five seconds, second inflation at 10 atm for 5 seconds.The balloon was able to deflate with no issues.Upon removal, the angiosculpt got caught on the patient's anatomy.The physician attempted to pull several times with the guide catheter being deep throated without success.Another wire passed the stuck angiosculpt and was placed in a diagonal position.Then, another balloon was advanced passed the angiosculpt partly inflated to try and dislodge the angiosculpt without success.The physician finally tugged on the shaft, and the shaft broke inside the patient and tried snaring it without success.By this time the patient started to decompensate, dropping bp, dropping o2 saturation, and code was started.Dye was injected, but did not see a perforation.It is likely that the patient developed global ischemia from the 3 vessel coronary disease as he was not a candidate for surgery or hemodynamic support.In retrospect, the physician suspected that the angiosculpt scoring element got imbedded in the calcific plaque, despite using rotational atherectomy in the vessel prior to the balloon angioplasty.The patient expired.This adverse event and product problem is being submitted because the distal portion of the shaft was retained in the patient.Additional intervention for device removal was performed; however, the patient expired during the procedure.
