It was reported that premature deployment and difficulty in removal occurred, requiring additional intervention.The 80% stenosed target lesion was located in the mildly tortuous and severely calcified right coronary artery (rca).Atherectomy and cutting balloons were used successfully without any complications.A 4.00 x 48mm synergy xd drug-eluting stent was advanced for treatment.However, upon delivery, the operator bent the proximal end of the delivery hypotube while attempting to complete crossing the stent.The operator removed the device because of the inability to inflate the delivery system.Upon removal, air was sucked into the balloon because of the change in pressure, which in turn, partially inflated the device, adding to the inability to remove it.It was noted the proximal end of the delivery system broke at the bent area outside the guide catheter, leaving the stent and balloon inside of the stent, partially stuck in the ostium of the rca and in the aorta.All systems and wires were successfully removed via snare through the arteriotomy access site.The procedure was completed with a 2 4.0mm synergy xd and the patient was kept overnight for evaluation and was discharged the next day without any complications.
