Methods: We report preliminary data of our ongoing, prospective FRiK registry, started in mid 2021. This registry investigates robotic-assisted percutaneous coronary intervention (R-PCI) using the Corindus CorPath GRX (Siemens Healtineers) focusing on success rates and safety, radiation dose of patients and personnel, long-term outcome (after 6, 12 and 24 months), as well as on economic aspects and the learning curve of the interventionalists. Moreover, R-PCI will be compared to manual PCI (M-PCI).
Results: So far, 37 patients (age 69 (59-78.5) years, BMI 28.3 (25.6-32) kg/m², male 81.1%), received R-PCI. PCI success rate was 100%, with 13.5% requiring manual assistance (figure 1). Rate of complications (myocardial infarction after PCI, dissection, stent thrombosis, pericardial effusion, target lesion revascularization and MACE (major adverse cardiovascular events) was 0%. Median dose-area product was 5203.6 (3810.4-6685.8) cGycm², contrast volume use 200 (150-280) ml, procedural time (diagnostic and intervention) 98 (78-121) min and fluoroscopy time 19.8 (14.6-27.1) min.
Conclusion: Preliminary results of R-PCI showed a high success rate, low rates for need of manual assistance, and a very high safety profile without any complications. Future steps will include a larger number of cases, direct comparison with M-PCI, as well as definitions of patient cases with optimal eligibility for R-PCI.
