Abstract：Objective To investigate the clinical effect of T-stenting with small protrusion(TAP)technique for non-left main bifurcation lesions of coronary artery,and to compare it with the DK-Crush technique.Methods Eighty patients with non-left main bifurcation lesions of coronary artery admitted to the first department of cardiology,the third affiliated hospital of Nanchang university from July 2014 to March 2017 were enrolled.They were equally divided into TAP group and DK-Crush group in random.The success rate of immediate percutaneous coronary intervention (PCI),the condition of bifurcation,the use of instruments(including number of stents and balloons),X-ray exposure time,contrast agent usage,incidence of stent thrombosis during hospitalization,and incidence of major adverse cardiac events(MACE,including sudden cardiac death,myocardial infarction,stent thrombosis,target vessel revascularization)after 12 months of follow-up were compared in the two groups.Results There was no significant difference in the success rate of immediate PCI between the two groups (P>0.05).In the TAP group,the number of balloons used and angiographic doses were both less compared with those in the DK-Crush group with statistical significance(P<0.05).The X-ray exposure time of the TAP group was shorter than that of the DK-Crush group with a significant difference(P<0.05).No significant difference was displayed in the incidence of MACE after 12 months of follow-up(P>0.05).There was no significant difference in the incidence of stent thrombosis during hospitalization and the incidence of intramural restenosis within 6 to 12 months between the two groups(P>0.05).Conclusion The short-term and long-term clinical efficacy of TAP in the treatment of non-left main bifurcation lesions of coronary artery is comparable to that of DKCrush,but it significantly shortens the exposure time,and reduces the amount of contrast agent,the use of surgical instruments,and medical expenses.
