Change in scar visibility in LGE-MRI with time after RF ablation procedure

Year: 2015

Type: article

Abstract: BackgroundAtrial fibrillation (AF) is the most common cardiac arrhythmia affecting more than 2 million people in North America.Radio-frequency (RF) and cryo ablations of the left atrium (LA) are effective for symptomatic, drug refractory AF patients.Reported success rates of the procedure vary significantly with AF recurrences ranging from 25-50%.Many AF recurrences occur early after the procedure.However, considerable fraction of recurrence happens later (> 3 months after the procedure) when post-ablation scar is believed to be stable.Late Gadolinium Enhancement (LGE) MRI is used to assess post-ablation scar in AF patients treated using RF and cryo ablations.The main aim of this work was to study how the visibility of post-ablation scar in LGE-MRI changes with time after RF ablation procedure.
