Angioplasty of the unprotected distal left main coronary artery with 2 stents presents the less favorable results in the segment. The double kissing (DK) technique and Culotte technique have been reported as effective for the treatment of bifurcation lesions, however this has never been tested for left main coronary artery.
The DKCRUSH-III study investigated the differences in adverse cardiac events, (MACE), at 12 months between the application of the Crush and Culotte techniques for distal artery angioplasty. A total of 420 patients with bifurcation lesions of the trunk in 15 centers were randomly assigned to receive treatment with the Crush technique (n = 210) or Culotte (n = 209).
The primary endpoint was the occurrence of MACE at 12 months, including cardiac death, myocardial infarction and/or target vessel revascularization. Restenosis and late lumen loss at six months were the secondary end points. The rate of stent thrombosis, (ST), was used as a security endpoint. The group of patients who received the Culotte technique had a higher restenosis rate compared with the Crushing group. Thrombosis was 1% for the Culotte and no thrombosis was reported for the Crushing group
