Background: Drug-eluting stents (DES) have been shown to reduce restenosis in many types of lesions. The purpose of this study is to assess the efficacy of DES in large real world cohort of patients with bifurcation lesions.

Methods & Results: The study included 616 consecutive patients. Age 64±12 year, male 78% and 35% had DM. Clinical presentation was stable angina 42%, acute coronary syndrome 47% and STEMI 11%. LAD/Diag PCI was performed in 55% of cases with Medina type 1.1.1, 1.0.1, 0.1.1 in 79% of lesions. First and second generation DES was used in 38.5% and 61.5% respectively. Two stent techniques were used in 39% of lesions.

	One year	2-year
12 month Death	3.4%	5%
12 month MI	3.1%	3.7%
12 month Definite Stent thrombosis	0.8%	1.0%
12 month TVR	7%	10.4%
12 month MACE	12%	17%

Conclusions: in this large cohort of patients with bifurcation lesions treated by DES showed acceptable one and two year clinical outcomes with low risk of stent thrombosis.
