Figure 2. Impact of RFCA on VENC-MRI: univariate analysis.
RFCA was associated with significant improvement in VENC-MRI. Patients with non-paroxysmal AF and low pre-RFCA VENC-MRI had greater improvement in VENC-MRI. Late recurrence had negative impact on VENC-MRI.
AF: atrial fibrillation; RFCA: radiofrequency catheter ablation; VENC-MRI: velocity-encoded cardiac magnetic resonance imaging.
