Catheter ablation provides an important treatment option for patients with both paroxysmal and persistent atrial fibrillation. It mainly involves pulmonary vein isolation and additional ablations in the left atrium in persistent cases. There have been significant advancements in this procedure to enhance the safety and effectiveness. One of them is the evolution of various imaging modalities to facilitate better visualization of the complex left atrial anatomy and the pulmonary veins in order to deliver the lesions accurately. In this article, we review the electroanatomic mapping systems including the magnetic-based and impedence-based systems. Each of these mapping systems has its own advantages and disadvantages. In addition, we also discuss the role of intracardiac echocardiography and three dimensional rotational angiography in atrial fibrillation ablation.
导管消融术为阵发性和持续性心房颤动患者提供了一种重要的治疗选择。它主要包括肺静脉隔离，对于持续性病例还需在左心房进行额外消融。该手术在提高安全性和有效性方面取得了重大进展。其中之一是各种成像方式的发展，以便更好地显示复杂的左心房解剖结构和肺静脉，从而精确地进行消融。在本文中，我们回顾了包括基于磁和基于阻抗的系统在内的电解剖标测系统。这些标测系统各有优缺点。此外，我们还讨论了心腔内超声心动图和三维旋转血管造影在心房颤动消融中的作用。
