About

The purpose of this study is to compare the accuracy of robotic-assisted percutaneous coronary intervention (PCI) using the CorPath GRX® System, versus standard PCI when treating ostial lesions.

CorPath GRX System (the Device) is a robotic-like device that is cleared for the remote delivery and control of heart catheterization devices. It helps doctors insert and move heart catheters (a thin, flexible tube) and similar types of devices inside patients blood vessels to treat the blockage in their heart.

The results will help to evaluate whether procedures using the CorPath GRX result in more accurate stenting (placing of a tube to keep heart vessel open) compared to standard PCI.

Full description

To assess accuracy of robotic-assisted PCI in obtaining full ostial lesion coverage and minimal protrusion compared to standard PCI.

Robotically assisted PCI offers the opportunity of performing minimal device movements (up to a minimum of 1 mm) in a stable and reproducible setting. This feature may be of great help when dealing with ostial lesions, whose treatment requires a precise stent positioning to avoid strut protrusion but also geographic miss of the lesion. Robotic-assisted PCI for ostial lesions showed encouraging results in large observational registries, but no study compared this approach with standard PCI.

The aim is to perform a randomized (1:1) study comparing standard (n=33) and robotic-assisted PCI (n=33) in obtaining full lesion coverage when treating ostial lesions (ostial left main will be excluded).

Primary endpoint of the study will be full ostial coverage as assessed by IVUS imaging, while secondary endpoints will be procedural success, vessel damage and number of protruding struts in the donor vessel as assessed by IVUS imaging.
