It was reported that the procedure was to treat a mildly tortuous, mildly calcified left circumflex to the main coronary artery.A 5x12mm nc trek balloon dilatation catheter (bdc) was advanced and inflated three times at 12 atmospheres each.The bdc was fully deflated holding negative pressure for 10-20 seconds each time.Once deflated and attempted to be removed, resistance was met with an unspecified guide catheter.The bdc and the guide catheter could not retract into the sheath; therefore, a j wire was advanced and removed the sheath, bdc and guide catheter all at once.A new sheath was advanced, but no other devices were used.There was no adverse patient sequela and no clinically significant delay in the procedure.No additional information was provided.
