Outcome After One Stent Technique in Bifurcation

European Bifurcation Club 2019, EBC 2019 - Barcelona, Spain NEWS 2 Outcome After One Stent Technique in Bifurcation: SB Strut Opening VS. Leave Alone Author: Chang-Wook Nam, MD, PhD, Keimyung University Dongsan Hospital, Korea PURPOSE OF THE CURRENT STUDY The aim of the current study is to evaluate the long-term clinical outcome according to SB opening procedure of bifurcation lesion after 1-stent crossover technique from COBIS 3 registry. LIMITATIONS Not free from selection bias as an observational study. Additional imaging study may have provided more information on the plaque progression The number of patients and events was too small to properly adjust for an adequate statistical power. The duration of a dual antiplatelet therapy for these higher- risk patients is still controversial SUMMARY There is the improvement of acute angiographic result in SB opening after simple crossover stenting. However, SB opening after simple crossover stenting did not show improvement in long-term clinical outcome compared to leave alone after simple crossover stenting. In addition, in both left main and true bifurcation, the simple crossover wit h additional SB opening did not showed a better long-term clinical outcome. Therefore, routine KBT after simple crossover may not be recommended. Provisional approach with FFR guidance will help to select the patients who need additional complex bifurcation procedure.
