Comparison between provisional Stenting and Two Stents Technique (DK-crush or Nano-crush) in Bifurcation Coronary Artery Lesions

Background: A higher incidence of significant adverse cardiac events is linked to bifurcation lesions. Objectives: To evaluate the efficacy of provisional stents versus a planned 2-stent DK-crush or Nano-crush procedure in patients with distal LM bifurcation lesions. Compare the short- and long-term results of using two stent techniques with provisional stenting techniques in a hospital. Methods: 150 patients were randomly assigned to two groups: group I (PS=75) and group II (2-stent DK=75) with lesions of the distal LM bifurcation. The first tactic, or provisional stenting procedure, involved stent placement in the (MB). The routine side branch stenting is the second (2 stent technique) strategy. Angiograms of the heart. Results: There were 18 females (24%) and 132 males (88%) in the study. Target lesion failure (TLF) was seen more frequently in group I compared to DK crush group II (5.3% vs. 0%; p=0.04), and stent thrombosis was observed at the 30-day follow-up. TLF occurred in 6 (8% of group one patients) in contrast to 2 (2.7%) of group two patients at the 6-month follow-up, with a significant difference between the two groups (p=0.028). Without a discernible difference, group I experienced higher rates of recurring anginal pain, stent thrombosis, target vessel MI, target lesion revascularization, and all-cause death. Conclusion: Regarding Target Lesion Failure (TLF) at the 6-month follow-up, the two-stent approach outperformed provisional stenting.
