Summary
This study introduces the solo technique for challenging percutaneous coronary interventions. It uses intravascular ultrasound (IVUS) guidance for precise guidewire manipulation, improving outcomes in complex cases.
Area of Science:
- Cardiovascular Interventions
- Interventional Cardiology
- Medical Device Technology
Background:
- Percutaneous coronary interventions (PCI) can be challenging, especially for chronic total occlusions (CTO).
- Existing techniques may have limitations in guidewire manipulation and re-entry within complex coronary anatomy.
- Intravascular ultrasound (IVUS) offers real-time visualization crucial for complex PCI procedures.
