Inclusion criteria

Key Inclusion Criteria * Symptomatic coronary artery disease including subjects with chronic stable angina, silent ischemia, and acute coronary syndromes including non-ST elevation and ST-elevation myocardial infarction * Subject is an acceptable candidate for treatment with a drug eluting stent in accordance with the applicable guidelines on percutaneous coronary interventions, manufacturer's Instructions for Use, and the Declaration of Helsinki * Subject requires treatment of a single de novo bifurcated lesion amenable to treatment with Resolute Onyx using the provisional stenting technique

Exclusion criteria

* Unprotected left main disease * Subjects with planned PCI of three vessel disease * Planned two stent technique (main branch and side branch) of a bifurcation * Subjects with more than one bifurcation lesion
