Abstract:
Objective To investigate the application of intravascular ultrasonography in guiding the performance of interventional management for coronary true bifurcation lesions. Methods A total of 62 patients with coronary true bifurcation lesions, who were admitted to authors’ hospital during the period from April 2010 to Jan. 2014 to receive double stenting treatment, were included in this study. The patients were randomly divided into intravascular ultrasonography group (IVUS group, n=32) and coronary angiography group(CA group, n=30). The minimal lumen diameter(MLD), the minimal lumen area(MLA), the reference lumen diameter (RLD), the length of the lesion and the diameter and length of the implanted stent were determined, and the results were compared between the two groups. During the follow-up period lasting for 12 months after percutaneous coronary intervention, the incidence of in - stent thrombus, target lesion revascularization (TLR) and major adverse cardiac events were recorded. Results The MLD values of the main artery and branches in IVUS group were higher than those in CA group, but the difference was not significant (P>0.05). The MLA, RLD, the diameter and length of the implanted stent in IVUS group were significantly larger than those in CA group (P<0.05). The incidence of in-stent thrombus, TLR and major adverse cardiac events in IVUS group were lower than those in CA group (P>0.05). Conclusion Intravascular ultrasound- guided double stent implantation for coronary true bifurcation lesions can help optimize the performance of stenting and improve the long-term outcome of percutaneous coronary intervention.
