Correlation of the Arrhythmia Mechanism and Substrate to Ablate Persistent Atrial Fibrillation Study
Sponsor: Ottawa Heart Institute Research Corporation
Summary
This is a pilot study to assess the usefulness of ECG mapping, and enhanced MRI and PET scan imaging in identifying atrial fibrosis and arrhythmia circuits involved in persistent atrial fibrillation and in guiding an innovative AF catheter ablation strategy. It is hypothesized that identifying these critical arrhythmia circuits and atrial fibrosis with enhanced imaging and performing an individualized innovative AF catheter ablation will result in higher procedural success rates.
