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

PURPOSE: 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. RECENT FINDINGS: 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.
