P ercutaneous coronary intervention (PCI) is an established treatment for unprotected (i.e., no bypass grafts to the left anterior descending artery and/or the circumflex) left main (ULM) lesions (1). Provisional stenting (i.e., stenting the main vessel and “jailing” the side branch, which is only treated if it becomes severely stenotic or occluded) is currently favored in most non-left main bifurcation lesions, because it is simple and easy to perform and often provides satisfactory results (1). Several 2-stent techniques have been developed for bifurcations involving both the main and the side branch, such as the T-stent, the culotte, and the double kissing crush (DK crush) technique. T-stent is usually used when the side branch originates at an approximately 70 to 90 angle from the main vessel, whereas culotte and DK crush are the currently preferred 2-stent techniques for <70 angle bifurcations. In this issue of the Journal, the DKCRUSH-V trial reports novel and important data demonstrating both incremental
