Abstract
We report a case of late stent malapposition occurring 6 months after intra coronary beta-irradiation detected by three-dimensional intravascular ultra sound, in spite of good apposition immediately after the procedure. Volumet ric quantification revealed that stent volume remained unchanged, whereas t otal vessel volume increased by 13% after 6 months within the stent area. T he increase of the vessel volume took place mainly in the proximal part of the stent, where the malapposition was located.
