An impenetrable proximal cap complicates chronic total occlusion (CTO) percutaneous coronary intervention (PCI). A novel retrograde balloon-assisted subintimal entry (BASE) technique successfully treated a CTO case with both proximal and distal cap impenetrability.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Medicine
Background:
- Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) presents challenges, particularly with impenetrable proximal caps.
- The retrograde approach is often necessary for CTO PCI when proximal caps are difficult to cross.
- Impenetrable distal caps further limit treatment options for CTO, often necessitating advanced techniques.
