Summary
Transient ST-segment elevation during cardiac ablation is rare. This case highlights inter-atrial septal stretch from a mapping catheter as a cause during pulmonary vein isolation.
Area of Science:
- Cardiology
- Electrophysiology
- Cardiac Procedures
Background:
- ST-segment elevation (STE) is an uncommon complication during cardiac ablation.
- Pulmonary vein isolation (PVI) is a common procedure for atrial fibrillation treatment.
Observation:
- Transient STE was observed during a PVI procedure.
- This elevation occurred upon introduction of a multipolar mapping catheter.
Findings:
- The STE was attributed to inter-atrial septal stretch.
- Various potential mechanisms for this STE phenomenon were explored.
Implications:
- Understanding this rare complication can improve patient safety during PVI.
- Recognizing septal stretch as a cause of STE aids in differential diagnosis.
