+Arms and interventions

Arm	Type	Interventions	Description
Jailed wire technique	Active comparator	Procedure: jailed wire technique
Modified jailed balloon technique	Experimental	Procedure: Modified jailed balloon technique

jailed wire technique (Procedure): protection of the side branch during main vessel coronary artery stenting by a wire placed in the side branch
Modified jailed balloon technique (Procedure): protection of the side branch during main vessel coronary artery stenting by a ballon placed in the side branch which is inflated simultaneously with main vessel stent deployment

+Outcome measures

Primary outcomes

side branch occlusion [intra-procedural]: TIMI III flow in the side branch < 3

Secondary outcomes

in-hospital MACE [immediately after the procedure]: cardio-vascular death, MI, target lesion revascularization
