Coronary artery stents were developed to prevent acute coronary closur
e and reduce restenosis after coronary angioplasty. A well-recognized,
although uncommon, complication of stent deployment is loss of contro
l, resulting in the stent being inadvertently deployed in an undesirab
le location. This case study describes a patient who underwent stent i
nsertion to the left anterior descending artery and had stent entrapme
nt in the left anterior descending/left main coronary artery. The sten
t was surgically removed, preventing unnecessary bypass grafting to a
normal circumflex artery.
