AIMS: We report a new stenting technique which was employed in 12 patients to treat coronary bifurcation lesions.

METHODS AND RESULTS: A stent is positioned in the main vessel together with a balloon in the side branch, which is positioned slightly proximal to the main vessel stent that also has enough length to cover the side branch ostium. Both the stent in the main vessel and the balloon in the side branch are inflated simultaneously. Following deflation, a double lumen is created in the main vessel, proximal to the bifurcation. The stent balloon is removed with the side branch balloon left deflated in its initial position. The main vessel is rewired with a third guidewire. The side branch balloon and guidewire are removed. The initial guidewire in the main vessel is directed to the side branch. A balloon is advanced and inflated in the side branch to dilate the struts of the main vessel stent that will provide the side branch entrance. The side branch balloon is left in place. A size matched balloon is advanced on the third guidewire that was advanced in the main vessel and inflated inside the stent with high pressure. Finally, kissing balloon inflation is performed at the bifurcation. Provisional stenting of the side branch can be performed when necessary. Final kissing balloon inflation is recommended after stenting of the side branch.

CONCLUSIONS: As a new coronary bifurcation stenting method, the Highway Technique has some advantages in side branch protection, with favourable immediate and 30-day clinical outcomes.
