Radiofrequency catheter ablation of pulmonary veins has emerged as an effective therapy for patients with symptomatic atrial fibrillation. Advances in real-time intracardiac echocardiography with 2D and Doppler color flow imaging have led to it integration in atrial fibrillation ablation procedures. It allows imaging of the left atrium and pulmonary veins, including identification of anatomic variations. It has an important role in guiding transseptal catheterization, imaging the pulmonary vein ostia, assisting in accurate placement of mapping and ablation catheters, monitoring lesion morphology and flow changes in the ablated pulmonary veins, hence allowing titration of energy delivery. Importantly, it allows instant detection of procedural complications.
射频导管消融肺静脉已成为治疗有症状心房颤动患者的一种有效疗法。二维和多普勒彩色血流成像实时心内超声心动图的进展已使其整合到心房颤动消融手术中。它可对左心房和肺静脉进行成像，包括识别解剖变异。它在引导经房间隔导管插入术、对肺静脉口进行成像、协助精确放置标测和消融导管、监测消融肺静脉中的病变形态和血流变化从而允许调整能量输送方面发挥着重要作用。重要的是，它可即时检测手术并发症。
