Advantage of intravascular ultrasound guiding left main lesion intervention / 心血管康复医学杂志

ABSTRACT

Objective:To explore advantage of intravascular ultrasound (IVUS) guiding coronary intervention .Meth‐odsA total of 100 patients with left main (LM) lesion were selected and equally divided into IVUS group (n=50 , received stent implantation under IVUS guidance ) and control group [n=50 ,received stent implantation after coro‐nary angiography (CAG) evaluation without IVUS examination ) .Instant condition after stent implantation and fol‐low-up results after 12 months were compared between two groups .Results:There were no significant difference in general data ,percentages of LM opening ,body part and tail lesions ,different types of plaques between two groups , P>0.05 all .During hospitalization ,there were no significant difference in percentage of emergency coro‐nary artery bypass grafting (0% vs .4% ) and mortality (0% vs .4% ) between IVUS group and control group (P>0.05) .However ,after 12 months ,compared with control group ,there were significant reductions in incidence rates of in-stent restenosis (16% vs .4% ) and late stent malapposition (34% vs .6% ) in IVUS group , P< 0.05 ,<0.01. Conclusion:IVUS guiding left main lesion intervention is helps to select more appropriate therapeutic plan , reduce tissue injury and improve long -term therapeutic effect .
