Abstract:
Objective 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).Methods CICT and IVUS examinations were performed on 30 diseased coronary vessels from 27 patients underwent PCI from Feb.2008 to Jul.2008.Results 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 OC T.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 underexpansion detected by OCT was 26.0% (same as that by IVUS).stent malappesition 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).Conclusions 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.
