The effect of completeness of revascularization on event-free survival at one year in the ARTS trial.

Objectives: We sought to assess the relationship between completeness of revascularization and adverse events at one year in the ARTS (Arterial Revascularization Therapies Study) trial.

Background: There is uncertainty to what extent degree of completeness of revascularization, using up-to-date techniques, influences medium-term outcome.

Methods: After consensus between surgeon and cardiologist regarding the potential for equivalence in the completeness of revascularization, 1,205 patients with multivessel disease were randomly assigned to either bypass surgery or stent implantation.
