Bifurcations constitute up to 20% of all percutaneous coronary interventions. Both the NORDIC I and British Bifurcation Coronary trials compared a two-stent strategy with main vessel (MV) stenting and provisional stenting of the side branch (SB). They consistently revealed a higher peri-procedural rate of myocardial infarction (MI) in the two-stent strategy, making provisional stenting the default strategy.
