The ROB-OSTIAL Study

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.
