一位47岁男性，患有未矫正的原发性房间隔缺损，主诉自1990年以来阵发性房颤频繁发作。IC类和III类抗癫痫药物未能控制复发，患者被转诊至我院进行电生理评估。在手术过程中，通过多电极标测证实房颤发作的局灶性起源于右上级和左肺静脉（PV）。因此，在选择性肺静脉血管造影术后，通过在相应的静脉心房交界处附近输送低能量射频脉冲进行肺静脉电断开尝试。为了便于识别肺静脉电断开，使用双导管技术，将参考四极导管远端放置在标测肺静脉中，将四极、4 mm头端、可操控导管直接放置在同一静脉的开口内进行标测和消融。目标区域被认为是那些...
A 47-year-old man with an uncorrected ostium primum atrial septal defect complained of frequent episodes of paroxysmal atrial fibrillation since 1990. Class IC and III antiarrhythmic drugs failed to control the recurrences, and the patient was referred to our institution for electrophysiological evaluation. During the procedure, the focal origin of the atrial fibrillation episodes from the right superior and left pulmonary veins (PVs) was demonstrated by means of multielectrode mapping. For this reason, after selective PV angiography, PV electrical disconnection attempts were performed by delivering low-energy radiofrequency pulses close to the corresponding venoatrial junctions. To facilitate the recognition of electrical PV disconnection, a double-catheter technique was used with a reference quadripolar catheter placed distally in the mapped PV and a quadripolar, 4-mm tip, steerable catheter positioned immediately within the ostium of the same vein for mapping and ablation. Target areas were considered those …
