Change in scar visibility in LGE-MRI with time after RF ablation procedure
نویسندگان
چکیده
Background Atrial 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.

Visibility of RF ablation lesions in native T1-weighted MRI reduces with time after ablation
Background Cardiac RF ablation is a widely accepted procedure for treatment of ventricular tachycardia and atrial fibrillation. Late gadolinium enhanced MRI (LGE-MRI) can be used to assess RF ablation lesions. However, LGE-MRI requires contrast injection and the visibility of lesions and appearance considerably change with time after the injection. Recently, native (non-contrast) T1-weighted (T...
متن کاملT2*-weighted MRI technique for visualization of RF ablation lesions
Background LGE-MRI is widely used to assess cardiac RF ablation lesions. However, LGE-MRI requires contrast injection and the appearance, dimensions and visibility of lesions in LGE-MRI noticeably change with time after ablation and time after contrast injection. Recently proposed non-contrast T1-weighted (T1w) technique is only applicable to visualize acute (< 3 days) RF lesions. The main goal...
متن کاملQuantitative magnetic resonance imaging analysis of the relationship between contact force and left atrial scar formation after catheter ablation of atrial fibrillation.
BACKGROUND Catheter contact force (CF) is an important determinant of radiofrequency (RF) lesion quality during pulmonary vein isolation (PVI). Late gadolinium enhancement (LGE) magnetic resonance imaging (MRI) allows good visualization of ablation lesions. OBJECTIVE This study describes a new technique to examine the relationship between CF during RF delivery and LGE signal intensity (SI) fo...

Background Atrial fibrillation (AF) is the most common cardiac arrhythmia affecting more than 5 million people in North America and Europe. Radio-frequency ablation (RFA) is effective in symptomatic, drug refractory AF. Reported success rates of the procedure vary significantly with AF recurrences ranging from 25-40%. The transmural extent of left atrial (LA) wall injury is difficult to assess ...

Background Radiofrequency (RF) ablation of myocardial tissue is a clinically acceptable therapy for atrial fibrillation and ventricular tachycardia. LGE-MRI has been used to assess immediately post-ablation RF lesions. It was shown that appearance of acute lesions in LGE-MRI changes with time after contrast injection [1,2]. Dickfeld, et al. [1] studied ventricular RF lesions delivered epicardia...
