Estimated Enrollment : 450 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: The European Bifurcation Club Left Main Study: A Randomised Comparison of Single Versus Dual Stent Implantation for Distal Left Main True Coronary Bifurcation Lesions
Study Start Date : February 2016
Estimated Primary Completion Date : August 2018
Estimated Study Completion Date : August 2020

Arm Intervention/treatment
Experimental: 1 Stent
Patients who are going to receive 1 stent in the main vessel and the side vessel will be treated with kissing ballon inflation
Device: 1 Stent
Stenting of main vessel should be undertaken with a wire jailed in the side vessel to preserve side vessel flow and access. Stent diameter should be chosen according to diameter of the main vessel immediately distal to the bifurcation. Distal left main should be dilated with a short non-compliant balloon. Side vessel should be rewired and a kissing balloon inflation should be undertaken. Balloon sizes should be according to the diameter of the main and side vessel with individual high pressure inflation followed by a final lower pressure kiss dilatation. Proximal stented portion in the left main coronary artery should be dilated to full expansion using either low pressure dilatation of the kissing balloon pair or a separate individual balloon. It is preferred that non-compliant balloons should be used to limit overstretching of vessels. In case of specific situations described in the protocol the operator may choose to implant a side vessel stent, using same process as described above.

Experimental: 2 Stents
Patients who are going to receive 2 stents in both vessels
Device: 2 Stents
Coronary guide wires should be passed to LAD and Cx/intermediate arteries respectively. One should be designated the main vessel and one should be designated the side vessel. The planned dual stent technique is at the discretion of the operator but should be one of culotte, minicrush, T or TAP. If a crush procedure is chosen, it should ideally be of the DK variety. Stent diameter should be chosen according to the diameter of the vessel immediately distal to the bifurcation. Wire jail, POT, non-compliant balloons, high pressure individual "ostial" dilatations and final dilatation of the stented proximal left main should be used in accordance with the advice of the EBC. Further treatment to proximal or distal aspects of the main vessel or side vessel can be continued at the discretion of the operator. At any stage, proximal or distal dissections may be treated as required with further stent implantations. At any stage, post-dilatations may be undertaken to optimise stent expansion.
