Event Description

It was reported that distal catheter shaft separation occurred requiring additional intervention.The 90% stenosed target lesion was located in the non-tortuous and calcified proximal right coronary artery.A 5.00 x 16mm synergy xd drug-eluting stent was implanted.However, when the physician removed the stent delivery system (sds), resistance was felt.The physician pulled the device and noticed on fluoroscopy that the sds balloon remained in the artery.The physician attempted to remove the detached sds balloon through snare, re-wire and performed antegrade dissection reentry technique but was unsuccessful.A surgery was scheduled in 30 days to remove the detached component.No patient complications were reported and the patient status was stable.
