Brief summary
KISS study is an investigator-initiated, multi-centre, prospective, randomized (1:1), parallel, two-arm, non-inferiority trial aiming to compare two bifurcation PCI procedures for Side Branch protection
Detailed description
In the treatment of bifurcation lesion, the role of side branch intervention for improving the safety of Percutaneous Coronary Intervention (PCI), when MB is treated according to the Murray law with a Proximal Optimization Technique (POT), remains unclear. The KISS study will evaluate the non-inferiority of no side branch intervention versus side branch ballooning, in the setting of single stenting with systematic proximal optimization technique.
Interventions
Side branch protection in the context of percutaneous coronary intervention for the treatment of bifurcation lesion

Eligibility
Inclusion criteria
1. Coronary artery disease requiring revascularization that is amenable to percutaneous coronary intervention (PCI) 2. Any de novo Medina type bifurcation lesion with \>70% lesion in the main vessel by visual assessment except Medina 0,0,1 if the planned strategy does not include a main branch stenting 3. Side branch diameter compatible with a PCI with stent implantation (≥ 2.25mm) 4. Side branch requiring a protection wire according to operator evaluation 5. Anatomy compatible with a proximal optimization technique 6. Post main branch treatment (stenting then POT): Absence of side branch occlusion Or low flow associated with ongoing ischemia (either chest pain or ST changes) 7. Male or female patient \>18 years old
Exclusion criteria
1. Acute myocardial infarction with ongoing ST-elevation 2. Cardiogenic shock 3. Requirement for ongoing hemodialysis 4. Life-expectancy limited to \<12 months due to co-morbid condition 5.
