Insights
A new Monorail balloon catheter can create a false image of coronary dissection during angioplasty. This artifact, seen as vessel staining, disappears upon balloon deflation and is not associated with complications.
Area of Science:
- Interventional Cardiology
- Medical Imaging
Background:
- Persistent contrast staining during percutaneous transluminal coronary angioplasty (PTCA) typically indicates coronary dissection.
- New medical devices require careful evaluation for potential imaging artifacts.
Purpose of the Study:
- To describe a novel false imaging finding during coronary angioplasty using the Monorail balloon catheter.
- To characterize the appearance and behavior of this artifact.
Main Methods:
- Retrospective review of seven patients undergoing angioplasty with the Monorail balloon catheter.
- Observation and documentation of contrast media staining patterns during balloon inflation and deflation.
Main Results:
- A false image of severe coronary dissection was observed in seven patients.
- This artifact appeared as distal vessel staining upon balloon inflation.
- The staining resolved completely after balloon catheter deflation.
Conclusions:
- The Monorail balloon catheter can produce a transient, false-positive image mimicking coronary dissection.
- This imaging artifact is not associated with any adverse patient outcomes.
- Awareness of this artifact is crucial for accurate interpretation during coronary interventions.
Abstract:
During percutaneous transluminal coronary angioplasty, the appearance of persistent staining in the vessel by contrast media suggests coronary dissection. We report seven patients in whom a false image of severe coronary dissection was observed during angioplasty performed with the new Monorail balloon catheter. This image emerges at the moment of balloon inflation, is distally located to the balloon, and disappears with balloon catheter deflation. No complications were associated with the appearance of this image.
