5-Year clinical follow-up of the COBRA (complex coronary bifurcation lesions: Randomized comparison of a strategy using a dedicated self-expanding biolimus A9-eluting stent vs. a culotte strategy using everolimus-eluting stents) study

ABSTRACT

OBJECTIVES:
We evaluated healing responses with optical coherence tomography, and long-term clinical outcomes after treatment with a dedicated stent versus a conventional culotte technique.

BACKGROUND:
Dedicated bifurcation stents have been proposed as an alternative treatment for coronary bifurcation lesions. The long-term performance of dedicated stents versus conventional dual-stent techniques for the treatment of complex coronary bifurcation lesions is unknown.

METHODS:
Forty patients with true coronary bifurcation lesions were randomized to treatment with a dedicated Axxess bifurcation stent in the proximal main vessel and additional Biomatrix stents in branches versus culotte stenting using Xience stents.

RESULTS:
The percentage of uncovered struts in each bifurcation segment at 9 months (primary endpoint) was similar between groups. Five-year clinical follow-up was available for all patients and included major adverse cardiac events [MACE; a composite of cardiac death, myocardial infarction (MI) and ischemia-driven target lesion revascularization (TLR)], target-vessel (TVR) and non-target-vessel revascularization (non-TVR), non-TLR and stent thrombosis. At 5 years, in the culotte group, one patient had undergone TLR and another suffered a clinical MI, resulting in 10% MACE versus none in the Axxess group. TVR (5% vs. 10%, P = 0.54) and non-TVR (5% vs. 20%, P = 0.39) rates were similar between the Axxess and culotte groups, respectively. There was no stent thrombosis.

CONCLUSION:
Compared with culotte stenting with Xience, complex coronary bifurcation stenting using a dedicated strategy combining the Axxess and Biomatrix stents results in similar stent strut coverage at 9 months, and excellent clinical outcomes at 5 years.
