Summary
Complete heart block (CHB) after left ventricular catheterization is rare. This case shows transient CHB in a patient with aortic stenosis, resolving spontaneously with pacing recommendations provided.
Area of Science:
- Cardiology
- Electrophysiology
Background:
- Complete heart block (CHB) is an uncommon complication of retrograde left ventricular catheterization.
- Patients with pre-existing bifascicular block and severe aortic stenosis may be at increased risk.
Observation:
- A patient with severe aortic stenosis and bifascicular block developed transient CHB during retrograde left ventricular catheterization.
- The cardiac rhythm disturbance resolved spontaneously without lasting effects.
Findings:
- This case highlights a rare but significant complication of a common cardiac procedure.
- Literature review provides recommendations for temporary and permanent pacing strategies in similar scenarios.
Implications:
- Understanding the risk factors and management of CHB post-catheterization is crucial for patient safety.
- Appropriate pacing strategies can effectively manage this complication, ensuring favorable patient outcomes.
