Patients
Between June 2002 and April 2003, we recruited 91 consecutive patients with symptomatic coronary heart disease who fulfilled the following inclusion criteria: 1) lesion located in a major bifurcation point regardless of morphology and angulation; 2) main vessel ≥2.5 mm diameter; 3) SB ≥2.25 mm diameter; and 4) significant stenosis in both main vessel and SB origin. Patients with diffuse SB lesions were excluded. Written informed consent was obtained from all patients.

Patients were randomly
Baseline and procedural data
Baseline clinical data are shown in Table I.There were no significant differences between groups in terms of age, sex, risk factors, or clinical condition. Table I also summarizes baseline angiographic characteristics in both groups of patients. There was no significant difference between the 2 groups with respect to the location of bifurcation, vessel size, severity of stenosis or type of bifurcation.10). The procedural characteristics are summarized in Table II.Lesions in the 2 groups were
Approach to bifurcated lesions in the era of drug-eluting stents
Percutaneous treatment of bifurcation lesions remains one of the most difficult areas to solve with catheter-based techniques. Recommendations and lessons learned from the bare stent era may become obsolete in today's practice. To stent the SB or not has already been widely discussed.1, 2, 3. We have proposed a 3-step strategy that provides good immediate and long-term outcomes by elective stent implantation at the main vessel and provisional SB stenting.1, 11 In the current era of drug-eluting
