Insights
Coronary catheter knotting during angiography is a complication, often from right coronary artery engagement attempts. A new percutaneous technique effectively reduces these knots, offering a novel management approach.
Area of Science:
- Interventional Cardiology
- Medical Device Technology
Background:
- Catheter knotting is a known complication during coronary angiography, particularly when engaging the right coronary artery.
- Existing literature on managing complex catheter knots is limited, necessitating new strategies.
Observation:
- Five cases of cardiac catheterisation complicated by significant catheter knotting were encountered.
- Simple catheter manipulation sometimes resolves kinks but is ineffective for tighter knots.
Findings:
- A novel percutaneous technique was developed and applied to reduce catheter knots.
- This technique offers a minimally invasive solution for a challenging complication.
Implications:
- The presented technique provides a new, effective method for managing coronary catheter knotting.
- This approach may improve procedural safety and efficiency in interventional cardiology.
- Further studies are warranted to validate this technique across a larger patient cohort.
Abstract:
During coronary angiography knotting of a coronary catheter is a recognised complication. It commonly results through excessive manipulation of a catheter in an attempt to engage the right coronary artery. Although simple manoeuvres of the catheter can often result in resolution of a kink, tighter knots may not be amenable to such measures. There is, however, little published material regarding its best management. We present five cases of cardiac catheterisation complicated by catheter knotting and present a novel percutaneous technique for their reduction.
