It was reported a balloon tear, stent entrapment, and stent dislodgement occurred.The patient experienced in-stent restenosis of an unknown stent, previously placed in the circumflex.During a procedure to address the restenosis, information suggested a balloon was inflated in the previously placed stent prior to advancing the 2.5 x 38 mm promus premier¿ drug-eluting stent.However, the stent delivery system was only able to advance halfway through the previously placed stent, and the promus premier¿ was then stuck in the previously placed stent.The physician attempted to remove the stent delivery system, but it was not able to be removed.A snare was used in an attempt to remove the stent and delivery system; however, during removal, a distal portion of the balloon tore off and the stent dislodged and fell into the aorta.The patient underwent surgery, during which the stent was retrieved from the aorta and the original procedure was completed.The balloon fragment remained stuck in the circumflex; that area of the circumflex was bypassed during surgery.The patient survived surgery, but died a number of hours following the procedure.The cause of death was not known.
