- W2375338421 abstract "Objective To explore the application of intravascular ultrasound(IVUS) imaging in assessing the characteristics of coronary lesion and guiding the percutaneous coronary intervention.Methods IVUS was used to assess the morphologic appearance of the vessel wall in 30 consecutive patients after coronary angiography.The mean age of these patients was 68.7±14.3 years.Among them,8 patients were female.IVUS with a motorized pullback system was performed in 46 segments of coronary vessel to assess the diameter of vessel,plaque character and the total vessel cross-sectional areas.The measurements of IVUS were compared with the results of quantitative coronary angiography(QCA).Results By QCA and IVUS examinating,among 46 segments measured the eccentric lesions were 25(54.3%) and 32(69.6%),respectively(P0.05),the target vessel calcification was 18(39.1%) and 30(65.2%),respectively(P0.01).The incidence of diameter stenosis was 62.15% and 74.35%(P0.01).IVUS was successfully performed in all 46 target vessels.All vessels but one were passed the re-examed,the only one was failed to pass IVUS catheter.8 segments(24.2%) with non-optimal stent deployment needed high pressure ballon re-dilatation.All patients were follow-up for one month and found no major adverse cardiac events.Conclusions IVUS can accurately assess morphologic appearance of coronary vessel wall and the characteristics of plaque.IVUS has shown to be a safe and efficient procedure for strategic adaptations during percutaneous coronary intervention." @default.
