It was reported that the device detached requiring additional surgery.The 90% stenosed target lesion was located in the severely tortuous and severely calcified right coronary artery (rca).A 1.50 mm rotapro and rotawire were selected for treatment.Dynaglide mode was initiated and the device was advanced just proximal to the lesion.After several ablations, the burr became stuck in the lesion and the device stalled.The device remained stuck in the lesion and in a stalled state despite many attempts to free the burr by initiating rotation in dynaglide mode.The advancer was then pulled, resulting in separation of the burr.After removal of the device from the body, it was confirmed that the rotawire had also separated approximately 30 cm from the tip within the guide catheter.The fragment migrated to the aorta and could not be retrieved via snare.Retrieval of the burr was attempted by inserting a trapping balloon and pulling the guide catheter, but the device remained stuck in the lesion.An additional guide catheter was inserted via an alternate vascular access site and a guidewire was then advanced to the lesion using the double-guide technique.Dilation with a small diameter balloon was performed, but the burr remained stuck within the lesion.The patient was transferred to another facility for surgical intervention.A thoracotomy was performed to retrieve the device fragments followed by a bypass procedure.The patient was stable post procedure.
