Bipolar radiofrequency ablation successfully treated perimitral flutter resistant to standard ablation. This novel approach for mitral isthmus block may improve outcomes for persistent atrial fibrillation patients.
Area of Science:
- Electrophysiology
- Cardiovascular Ablation Technologies
Background:
- The mitral isthmus is a common target for radiofrequency ablation in persistent atrial fibrillation.
- Standard unipolar ablation for mitral isthmus block has modest acute success and high rates of late reconduction, potentially leading to proarrhythmia.
- Incomplete lesions can result in recurrent arrhythmias like perimitral flutter.
