Treatment of Bifurcation Lesions: Has DK Crush"ed" the Competition?

This paper reviews the double-kiss crush (DK crush) technique in coronary artery bifurcation lesions. The technical aspects of the procedure and the clinical data supporting its use are summarized.

Randomized studies support the adoption of DK technique in complex bifurcation lesions for both left main and non-left-main lesions. For true bifurcation lesions, DK crush may become the default technique for lesions in which the side-branch disease is complex and long. Optimal technique is essential for obtaining the clinical outcomes noted in the DKCRUSH randomized studies.
