Dislodged stent in left main coronary artery

A 45-year-old man, with recent onset effort angina was taken for percutaneous coronary intervention for significant left anterior descending artery (LAD) stenosis. During procedure, there was resistance to advance the stent across the lesion. When the stent was withdrawn to re-dilate the lesion, it dislodged from the balloon catheter completely and was floating over the guidewire from left main coronary artery to proximal LAD. This case demonstrates how to prevent and manage stent dislodgement.
