To collect data on the routine patterns of use, safety and effectiveness, including the clinical and technical performance of the CorPath GRX System, in the delivery and manipulation of coronary guidewires and stent/balloon catheters, and manipulation of guide catheters during PCI procedures in the first 231 patients treated with the CorPath device in Japan.

This is a single-arm, open-label, multi-center patient registry in Japan of the CorPath GRX System to examine its performance during PCI procedures and patient outcomes through 72 hours post-procedure or hospital discharge, whichever occurs first.

Inclusion Criteria:

1. Age ≥ 20 years;
2. Patients with coronary artery disease with clinical indication for PCI;
3. Patient deemed appropriate for robotic-assisted PCI; and
4. The subject has been informed of the nature of the study, agrees to its provisions and has provided written informed consent, unless the EC has waived informed consent.

Exclusion Criteria:

1. Failure/inability/unwillingness to provide informed consent, unless the EC has waived informed consent; or
2. The Investigator determines that the patient or the coronary anatomy is not suitable for robotic-assisted PCI.
