Buffle et al are to be congratulated for shedding more light on the electrophysiologic links regarding atrial fibrillation recurrence post radiofrequency catheter ablation. The different approaches of left atrium volume and left atrium diameter assessment employed in this study, is a limitation that should not go unnoticed, since angiographically calculated left atrium volume overestimates volume as compared to 3D echo measurements. Further, the timing of change has been reported to have prognostic significance; namely left atrium diameter reduction within the 3 month blanking period has been reported to independently predict prolonged arrhythmia free survival. Hence, we firmly believe that future studies should examine any potential correlations between left atrium diameter and recurrence mechanisms.
布弗莱等人在阐述射频导管消融术后心房颤动复发的电生理联系方面做出了重要贡献。这项研究采用了不同的左心房容积和左心房直径评估方法，这是一个不容忽视的局限性，因为与 3D 超声测量相比，血管造影计算的左心房容积会高估容积。此外，变化的时间已被报道具有预后意义；即 3 个月的空白期内左心房直径的减小已被报道可独立预测心律失常无复发的生存时间延长。因此，我们坚信未来的研究应该检查左心房直径与复发机制之间的任何潜在相关性。
