Brief Summary:
The objective of this randomized safety and observational study is to demonstrate CorPath GRX chronic total occlusion PCI is safe, and that Cardiac Catheterization Laboratory staff have no additional exposure to radiation when compared to conventional manual chronic total occlusion PCI procedures without added procedure time.

Condition or disease Intervention/treatment
Coronary Artery Disease Chronic Total Occlusion of Coronary Artery Percutaneous Coronary Intervention Device: Robotic CTO PCI Procedure: Conventional (Manual) CTO PCI

Detailed Description:
This is prospective, dual-arm, randomized, multi-center, observational study comparing patient outcomes and staff radiation exposure in chronic total occlusion PCI procedures through 48 hours post procedure or hospital discharge, whichever occurs first.

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Clinical Success [ Time Frame: 48 hours ]
    Defined as successful CTO PCI revascularization with achievement of <30% residual diameter stenosis (visual estimate) within the treated segment and restoration of antegrade TIMI grade 3 flow, without in-hospital major adverse events (MAE).

  2. In-hospital Major Adverse Events (MAE) [ Time Frame: 48 hours ]
    Number of MAE events that occurs within 48 hours of the CTO PCI procedure or hospital discharge, whichever occurs first.


Secondary Outcome Measures :
  1. Operator Radiation Exposure [ Time Frame: Procedure ]
    Cumulative dose the physician receives as recorded from electronic pocket dosimeter during procedure.

  2. Staff Radiation Exposure [ Time Frame: Procedure ]
    Cumulative dose the staff receives as recorded from electronic pocket dosemeter during procedure.

  3. Patient Radiation Exposure [ Time Frame: Procedure ]
    DAP (dose-area-product) and cumulative dose/air kerma as recorded during the procedure

  4. Fluoroscopy Time [ Time Frame: Procedure ]
    Total fluoroscopy (min.) utilized during the procedure as recorded by an Imaging System.
