Intravascular ultrasound study of SAFE-CUT~(TM)balloon angioplasty in coronary heart disease / 中国介入心脏病学杂志

ABSTRACT

70%(59 male and 22 female,mean age 61?11 years)were enrolled in the study,IVUS was done in 55 cases before and after percutaneous coronary intervention(PCI)with 24 patients from the SFCT group and 31 patients from the conventional percutaneous coronary angioplasty(POBA).Quantitative coronary angiography(QCA)measurements included minimal lumen diameter(MLD),reference lumen diameter(RLD)and diameter stenosis(DS);IVUS measurements include external elastic membrane area(EEMA),minimal lumen area(MLA),and area stenosis(AS),style of endomembrane tear and dissection.Results All the target lesions were successfully dilated in both groups without serious complications.Mean dilated pressure was lower in the SFCT group than that in the POBA group(871.4 kPa vs 1 013.2 kPa P
