Figure 1 Experimental Design of the Study

Three hundred and forty-seven patients with unprotected left main (UPLM) disease were screened. Patients who were eligible for the study and signed informed consent (105 patients) were randomized to both treatment arms. Seventeen patients were not randomized due to their refusal. Patients not eligible for the study were included in the LE MANS registry. CABG = coronary artery bypass grafting; PCI = percutaneous coronary intervention.
