Summary
Transradial coronary intervention using a novel SheathLess guiding catheter allows for simultaneous kissing stenting (SKS) without needing a larger sheath. This technique simplifies the procedure, avoiding femoral conversion or extra access for complex interventions.
Area of Science:
- Interventional Cardiology
- Vascular Access Techniques
- Medical Device Innovation
Background:
- Transradial coronary intervention typically uses 5 or 6 Fr sheaths due to radial artery size limitations.
- Simultaneous kissing stenting (SKS) requires larger guiding catheters (≥7 Fr), posing challenges for the transradial approach.
- Current methods often necessitate femoral artery conversion or additional access for SKS via transradial access.
Observation:
- A novel hydrophilic 7.5 Fr SheathLess guiding catheter was evaluated.
- This catheter has an outer diameter comparable to a 6 Fr sheath but an inner diameter of 7.5 Fr.
- The catheter was used to perform SKS through a transradial approach.
Findings:
- The SheathLess guiding catheter enabled successful SKS via the transradial route.
- The procedure was performed smoothly, overcoming the size limitations of standard transradial access.
- This approach eliminated the need for femoral conversion or additional arterial access.
Implications:
- This innovation expands the applicability of the transradial approach for complex coronary interventions like SKS.
- It offers a potentially safer and more efficient alternative to traditional methods.
- Facilitates complex stenting procedures through a single, smaller arterial access point.
