Intracoronary Imaging and Histopathology of Late Phase In-Stent Restenosis after Coronary Stent Implantation
Figure 2
Optical coherence tomography (OCT) and intravascular ultrasound (IVUS) findings of in-stent restenosis before balloon angioplasty. (a) OCT showed homogeneous high intensity in the distal segment. IVUS revealed a homogeneous and slightly hyperechoic material. (b) High intensity accompanied by attenuation was observed in the proximal segment by OCT. Peristent area was hypoechoic by IVUS; however, there was no clear difference between (a) and (b) compared to OCT. (From J Invasive Cardiol 23: E86–E91, 2011 with permission).
