Evaluation of the R-One robotic system for percutaneous coronary intervention: the R-EVOLUTION study
Authors' conclusion
This study suggests that robotic PCI using R-One is safe and effective with markedly lower radiation exposure to the operator.
Study context
- Population
- Patients with a de novo coronary artery stenosis (length <38 mm, reference diameter 2.5–4.0 mm) undergoing stent implantation; recent STEMI, ostial or left main lesion, bifurcation, severe tortuosity or calcification excluded
- Participants
- 62 patients64 lesions
- Outcome
- Clinical success (absence of major intraprocedural complications) and technical success (successful advancement and retraction of all PCI devices without total manual conversion)
