A Randomized Clinical Study Comparing Double Kissing Crush With Provisional Stenting for Treatment of Coronary Bifurcation Lesions: Results From the DKCRUSH-II (Double Kissing Crush versus Provisional Stenting Technique for Treatment of Coronary Bifurcation Lesions) Trial
2011
Objectives The present study aimed to investigate the difference in major adverse cardiac events (MACE) at 12 months in patients with coronary bifurcation lesions after double kissing double crush (DK crush) or provisional stenting (PS) techniques. Background Provisional side branch (SB) stenting is preferable to DK crush because it has been associated with fewer complications. It is unknown which strategy would provide the best results. Methods From April 2007 to June 2009, 370 unselected patients with coronary bifurcation lesions from 7 Asian centers were randomly assigned to either the DK or the PS group. Additional SB stenting in PS was required if final results were suboptimal. The primary end point was the occurrence of MACE at 12 months, including cardiac death, myocardial infarction, or target vessel revascularization (TVR). Secondary end point was the angiographic restenosis at 8 months. Results There were 3 procedural occlusions of SB in the PS group. At 8 months, angiographic restenosis rates in the main vessel and SB were significantly different between the DK (3.8% and 4.9%) and the PS groups (9.7% and 22.2%, p = 0.036 and p Conclusions DK crush was associated with a significant reduction of TLR and TVR in this unselected patient population. However, there was no significant difference in MACE between DK and the PS groups.
