ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the value of combined optical coherence tomography (OCT) and intravascular ultrasound (IVUS) examinations in detecting coronary artery plaque during percutaneous transluminal coronary intervention (PCI).</p><p><b>METHODS</b>OCT and IVUS examinations were performed on 30 diseased coronary vessels from 27 patients underwent PCI from Feb. 2008 to July. 2008.</p><p><b>RESULTS</b>Seventeen vulnerable plaques (4 intima tearing which were not detected by IVUS), 5 plaque rupture (1 out of 5 was detected by IVUS), 5 thrombus lesions (1 out of 5 was found by IVUS), 12 thin-cap lipid-rich lesions (2 detected by IVUS) were detected by OCT in 22 lesions (without 8 lesions post DES stents). Analysis result of plaque burden by IVUS was superior to that obtained by OCT. In 8 DES stents (implanted for 6 months to 4 years), OCT detected 2 had severe restenosis, 6 stents struts were completely covered with neointima without restenosis, 1 stent had aneurysm-like dilatation. IVUS results were similar except for limitations on exactly detecting neointima post stenting. In 19 newly implanted stents, the incidence of stent under-expansion detected by OCT was 26.0% (same as that by IVUS), stent malposition was 63.2% (10.5% by IVUS, P < 0.01), near stent tearing was 10.5% (not detected by IVUS), tissue prolapse between coronary stent struts was 52.6% (10.5% in IVUS, P < 0.05).</p><p><b>CONCLUSIONS</b>OCT imaging is superior to IVUS on detecting vulnerable plaques and change of structure around stents while IVUS is superior to OCT on estimating plaque burden in patients underwent PCI.</p>
