In plain language
In 10 patients at one Chinese centre, second-generation robotic percutaneous coronary intervention (PCI) was completed without manual conversion or major adverse events. Staff radiation dose was not measured, so this study does not show reduced exposure for the fluoroscopy team.

What it found
All 11 lesions in 10 patients were treated successfully with the second-generation robotic system, with no conversion to manual operation and no in-hospital major adverse cardiac events (MACE).
Key figures: 11/11 (100%) clinical success
Fluoroscopy time and air kerma were numerically lower in later than early cases, but differences were not statistically significant.
Key figures: fluoroscopy 20.3 ± 8.2 vs. 12.5 ± 4.6 min, P = 0.16; air kerma 1932 ± 978 vs. 1007 ± 70 mGy, P = 0.31
Mean procedure and fluoroscopy times across all cases were reported; live demonstration cases inflated times.
Key figures: procedure time 57.7 ± 26.4 min; fluoroscopy 18.2 ± 8.0 min; air kerma 1681 ± 870 mGy
Operators worked seated in a radiation-shielded cockpit, but operator radiation dose was not measured in this study.
Limits to keep in mind
Single-centre series of 10 patients with two operators, no manual-PCI comparison group, and no measurement of staff or operator radiation dose.
