Intravascular imaging with OCT was carried out which showed in-stent diffuse backscattering lesion with minimum stent area of 2.62 mm2 which could be either due to an underexpanded stent or probably malapposed struts at 4-6 o'clock positions [Figure 3].

Repeat OCT poststenting was carried out, which showed good apposition and minimum stent area of 4.97 mm2 with no evidence of underexpansion or geographical miss [Figure 4].
