Comparison of simple vs complex stenting in patients with true distal left main bifurcation lesions
Catheterization and Cardiovascular Interventions Sep 12, 2020
Lee CH, Ahn JM, Kang DY, et al. - Researchers used two large clinical registries to compare clinical results after single vs dual stenting for true distal left main (LM) bifurcation lesions. Participants were patients having true distal LM bifurcation lesions (type 1,1,1 or 0,1,1: both left anterior descending and circumflex artery > 2.5 mm diameter) undergoing percutaneous coronary intervention with drug‐eluting stents. Target‐lesion failure (TLF), defined as a composite of cardiac mortality, target‐vessel myocardial infarction (MI), or target‐lesion revascularization, was the primary outcome. At 3 years, a similar adjusted risk of TLF was found between the single‐ and dual‐stenting groups. Both the groups also showed similar adjusted risks for mortality, MI, repeat revascularization, or stent thrombosis. These observations should be corroborated or refuted via large, randomized clinical trials.
