The Rolex Registry (Revascularization Of LEft Main With Resolute onyX)

The ROLEX Registry (Revascularization Of LEft Main With Resolute onyX) A Multicenter Prospective Registry of the Onyx Resolute Stent for the Treatment of Unprotected Left Main Coronary Artery Disease.

The primary objective of this study is to assess the safety and efficacy of the new-generation zotarolimus-eluting stent Resolute Onyx in the treatment of unprotected left main coronary artery disease (ULMCAD), both isolated or in association with two- or three-vessel coronary artery disease.

The ROLEX study is a prospective, non-randomized, European, multi-center registry.

Four hundred and fifty patients with unprotected left main coronary artery disease (ULMCAD) will be enrolled at up to 40 European sites. The main objective of the study is to assess the safety and efficacy of the new-generation zotarolimus-eluting stent Resolute Onyx in the treatment of ULMCAD, both isolated or in association with two- or three-vessel coronary artery disease
