Comparison of clinical outcomes of double kissing crush (DKC) and mini-crush (MC) techniques in patients with complex coronary bifurcation lesions is lacking. This study sought to determine the clinical results of DKC and MC stenting techniques in mid-term follow-up. This retrospective study included a total of 269 consecutive patients with complex bifurcation lesions who underwent percutaneous coronary intervention; 132 (49%) of them were treated with MC technique, whereas 137 (51%) treated with DKC technique. The primary end point was target lesion failure (TLF), defined as the combination of cardiac death, target vessel myocardial infarction, or clinically driven target lesion revascularization. This is the first study to compare the cardiovascular outcomes of DKC and MC stenting techniques in patients with complex bifurcation lesions. The SYNTAX scores were similar in both groups (23 [20 to 30] vs 23 [19 to 28], p = 0.631)]. The number of balloons (6.31 ± 1.80 vs 4.42 ± 0.87, p <0.001) and guidewires (3.55 ± 0.83 vs 2.86 ± 0.74, p <0.001) used, fluoroscopy time (21.55 ± 7.05 vs 16.66 ± 4.19 minutes, p <0.001), and procedure time (80.42 ± 27.95 vs 69.61 ± 18.97 minutes, p <0.001) were significantly higher in the DKC group. The rate of composite TLF was similar in complex bifurcation patients treated with MC than those treated with the DKC technique (14% vs 12%, p = 0.453). Moreover, both groups had similar rates in terms of cardiac death or all-cause death, target vessel-related myocardial infarction, clinically driven target lesion revascularization, and stent thrombosis. In conclusion, the present study showed that both techniques of bifurcation treatment met high angiographic success with low complication and similar TLF rates.
