Summary
Coronary dissection during percutaneous coronary intervention (PCI) can create cavities that hinder device delivery. A balloon spacer technique, guided by intravascular ultrasound (IVUS), can be a successful bailout strategy when rewiring alone fails.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Devices
Background:
- Coronary dissection during percutaneous coronary intervention (PCI) can lead to dissection-related cavities.
- These cavities may destabilize guidewire passage and device delivery.
- Stable true-lumen device delivery is crucial for successful PCI outcomes.
