Summary
Transradial coronary intervention (TRI) is feasible and safe for Japanese patients. This approach demonstrated significantly lower local complications compared to transfemoral coronary intervention (TFI).
Area of Science:
- Cardiology
- Vascular Surgery
Background:
- Transfemoral coronary intervention (TFI) is a common procedure.
- Transradial coronary intervention (TRI) offers potential advantages but requires evaluation in diverse populations.
Purpose of the Study:
- To assess the feasibility and safety of transradial coronary intervention (TRI) in Japanese patients.
- To compare TRI outcomes with transfemoral coronary intervention (TFI) in this population.
Main Methods:
- Retrospective comparison of TRI (1,791 lesions/1,360 patients) and TFI (966 lesions/793 patients).
- Evaluation of success rates (arterial puncture, cannulation, lesion, patient) and major/local complication rates.
- Post-procedure radial artery assessment (palpation, Doppler) in 294 patients to determine occlusion rates.
Main Results:
- Similar success rates were observed between TRI and TFI groups.
- Major complication rates showed no significant difference between the two methods.
- Local complications were significantly lower in the TRI group (0.3% vs. 3.3%, P < 0.001).
- Radial artery occlusion rates were 5% when sheath removal was delayed by 3 hours, and 0% when removed immediately post-procedure.
Conclusions:
- Transradial coronary intervention (TRI) is a safe and feasible option for Japanese patients.
- TRI is associated with a significant reduction in local complications compared to TFI.
- Immediate sheath removal post-TRI minimizes the risk of radial artery occlusion.
