Abstract:
Objective To evaluate the efficacy and safety of double lumen microcatheters in chronic coronary artery total occlusion(CTO)lesions at bifurcation during percutaneous coronary intervention(PCI).Methods From October 2013 to March 2015,we retrospectively analysed the application of double lumen microcatheter with bifurcation CTO lesions and reviewed the patients' clinical features,coronary angiography,intervention operation success rate,complications rates and incidence of major adverse cardiac events(including all-cause death,nonfatal myocardial infarction and target vascular remodeling).Results Twenty-three CTO lesions at bifurcation were treated with double lumen microcatheters,stenting were performed in 21 lesions and 2 lesions only received PTCA due to small blood vessel size.The operation success rate was 100％.All the 11 right coronary lesions and 3 left coronary lesions were managed using single stenting technique.Double stenting strategy was used in 9 left coronary lesions including 4 cases with mini-crush technique,4 cases with modified culottes technique and one case with modified T technique.All double stenting procedures were completed by kissing balloon expansion.There was no major adverse cardiac event occured during and after operation.Conclusion Double lumen microcatheters are useful in PCI treatment of bifurcation CTO lesions.
