ABSTRACT


OBJECTIVES - The authors sought to investigate whether the impact of treatment strategies on clinical outcomes differed between patients with left main (LM) bifurcation lesions and those with non-LM bifurcation lesions.


BACKGROUND - Few studies have considered anatomic location when comparing 1- and 2-stent strategies for bifurcation lesions.

METHODS - We compared the prognostic impact of treatment strategies on clinical outcomes in 2,044 patients with non-LM bifurcation lesions and 853 with LM bifurcation lesions. The primary outcome was target lesion failure (TLF) defined as a composite of cardiac death, myocardial infarction (MI), and target lesion revascularization.

RESULTS - The 2-stent strategy was used more frequently in the LM bifurcation group than in the non-LM bifurcation group (40.3% vs. 20.8%, p < 0.01). During a median follow-up of 36 months, the 2-stent strategy was not associated with a higher incidence of cardiac death (hazard ratio [HR]: 1.24; 95% confidence interval [CI]: 0.72 to 2.14; p = 0.44), cardiac death or MI (HR: 1.12; 95% CI: 0.58 to 2.19; p = 0.73), or TLF (HR: 1.39; 95% CI: 0.99 to 1.94; p = 0.06) in the non-LM bifurcation group. In contrast, in patients with LM bifurcation lesions, the 2-stent strategy was associated with a higher incidence of cardiac death (HR: 2.43; 95% CI: 1.05 to 5.59; p = 0.04), cardiac death or MI (HR: 2.09; 95% CI: 1.08 to 4.04; p = 0.03), as well as TLF (HR: 2.38; 95% CI: 1.60 to 3.55; p < 0.01). Significant interactions were present between treatment strategies and bifurcation lesion locations for TLF (p = 0.01).

CONCLUSIONS - The 1-stent strategy, if possible, should initially be considered the preferred approach for the treatment of coronary bifurcation lesions, especially LM bifurcation lesions. (Korean Coronary Bifurcation Stenting [COBIS] Registry II; NCT01642992).
