  4. 4. Impact of symmetricityOtake H, JACC Intrv, 2009, 2,459KBTAsymmetrical stent expansion leads to uneven intimalgrowth and frequent thrombus attachment withuncovered struts after SES deployment.SEI: stent eccentricity indexNUS: neointima unevenness scoreKBT induces more asymmetrical stent expansion.What are its effects on neointimalialization after2nd generation DES deployment?
  5. 5. Purpose of the studyStudy-1To compare acute phase and mid-term outcome ofprovisional stenting between EES and SES deploymentunder the IVUS guidance.Study-2To investigate whether asymmetrical expansion in thebifurcation lesion leads to more disturbance ofneointimalization.EndpointsStudy-1Major adverse cardiac events (MACE) during 9-mo F/U periodDeath, Myocardial infarction, Target lesion revascularization(TLR), Target vessel revascularization (TVR), Stent thrombosisStudy-2OCT abnormal findings (unevenness of intimal growth,uncovered struts, thrombus attachment)

  14. 14. Conclusion• The EES deployment under the IVUS-guidance in thecoronary bifurcation lesion brought a favorable TLR ratecompared to the SES.• Although the KBT induced more SB dissection requiringstenting and asymmetrical stent expansion in theproximal MV, it maintained lower levels of SB stenosisand larger proximal MV lumen during the 9-month F/Uperiod without any increase in MACE.• Asymmetrical stent expansion induced by KBT did notresult in more disturbance in neointimalization, whichmight be influenced by the improvement inmalapposition or overstretch in the proximal MV.
