Brief Summary
In the setting of single stent strategy for treatment of bifurcation, we investigate to compare simple strategy as "provisional final kissing balloon technique(fKBT)" to complex one as "routine FKBT", focusing on actual myocardial ischemia assessed by scintigraphy in 7-month and to examine optimal endpoint of side branch ostium.

Study Arms (2)
Provisional fKBT
ACTIVE COMPARATORStent technique that final kissing balloon technique(fKBT) is performed if side branch flow was aggravated to TIMI0-2 after stent deployment
Routine fKBT
ACTIVE COMPARATORStent technique that fKBT was mandatory irrespective of side branch flow after stenting.
Interventions
Provisional use of fKBT only when SB flow is aggravated to TIMI0-2 after stenting for non-left main bifurcation. Additional stenting for SB is recommended if residual stenosis (\>50% in visual) or TIMI flow grade (\<TIMI 3) was seen at SB after fKBT. Stent type: Everolimus-eluting stent only
