Optical coherence tomography-guided treatment of very late stent thrombosis caused by inaccurate stent deployment in a bifurcation.

: A 65-year-old man presented at our institution with anterior wall reinfarction, due to very late stent thrombosis, 4 years after primary angioplasty on the first bifurcation of the left anterior descending artery. Using intravascular optical coherence tomography, we identified stent malapposition in the proximal left anterior descending artery, occurring during the first primary angioplasty, as the probable cause of the very late stent thrombosis. Imaging with optical coherence tomography guided our treatment strategy of mechanical and pharmacological thrombectomy, followed by staged stent postdilatation.
