It was reported that the procedure was to treat a heavily calcified, mildly tortuous right coronary artery (rca).The 3.5x38mm xience prime stent was deployed; however, the stent balloon only partially deflated.Multiple methods to deflate the balloon was attempted including; with an unspecified indeflator applying negative pressure and applying negative pressure with a syringe fixing to the stent hub, but unsuccessful.The stent delivery system was pulled with force and the distal shaft separated, remaining in the patient.The patient was immediately sent for emergency open heart surgery and the distal shaft portion was removed along with the stent from the rca.No clinically significant delay was reported.No additional information was provided.
