RESUMO
BACKGROUND: Provisional T-stenting (PS) is generally recommended to treat patients with coronary bifurcation disease (CBD) percutaneously, but PS may not fit all complex bifurcation anatomies. Therefore, several types of up-front 2-stent techniques have been described. We aimed to identify the best percutaneous coronary intervention (PCI) technique to manage patients with CBD. METHODS: We systematically reviewed randomized controlled trials (RCTs) including patients undergoing CBD PCI which included several types of PCI techniques-PS, double-kissing (DK) crush, T-stenting and protrusion, culotte, dedicated bifurcation stents, crushing, and T-stenting-and we compared device-oriented clinical events (DOCEs), a composite of cardiac death, target-vessel myocardial infarction, stent thrombosis, and target-lesion or target-vessel revascularization, in a network meta-analysis. We included 26 RCTs, leading to a pooled population of 10,339 patient-years and a total of 1229 DOCEs. RESULTS: The DK-crush technique was associated with the lowest DOCE rate, with a relative risk of 0.62 (95% CI 0.42-0.92) compared with the PS technique. DK-crush had the highest probability (model likelihood 90.2%, area under the cumulative ranking curve 98.0%) of being the best technique among those explored to reduce DOCEs in patients receiving CBD PCI. CONCLUSIONS: When a 2-stent strategy is considered in a patient with CBD, the DK-crush technique reduces DOCEs compared with other bifurcation techniques based on all available RCTs.
