简要总结
Zero-fluoroscopy is the dream of all interventionists, and as low as reasonably achievable (ALARA) is the goal the investigators can manage at this moment. Trans-septal puncture (TSP) is the most pivotal step in the ablation procedure for left heart procedure, including atrial fibrillation ablation, and it is the only step that still needs fluoroscopy in the era of 3D electroanatomical map. With the incorporation of intracardiac echocardiography (ICE), the dream of zerofluoroscopy can be achieved.
Because the imaging offered by fluoroscopy or ICE is so different in terms of the advantages and shortages, the best TSP protocols might be different. Currently, in the literature, two techniques are commonly referred. However, no comparison has been made between these two techniques. Therefore, this study is to compare the safety and efficiency of these two techniques, also to observe the transition of a senior EP doctor who has been experienced in fluoroscopy-guided TSP, hoping to establish the learning curve for future reference of zerofluoroscopy promotion.

研究组 & 干预措施
Echocardiography
The movement of the puncture needle was monitored using intracardiac echocardiography rather than fluoroscopy. All other steps followed the conventional approach.
干预措施: J Wire (Procedure)
3D mapping system
Guided by the ablation catheter image on the 3D mapping system, the long sheath was advanced to the puncture site and then exchanged for a puncture needle. The entire procedure was monitored with intracardiac echocardiography.
干预措施: 3D mapping system (Procedure)
结局指标

Time duration from femoral venous access to the completion of both the first and second transseptal puncture (TSP). Unit of Measure: Minutes
Fluoroscopy usage and radiation dose
时间窗: during the procedure
Whether fluoroscopy was used during the procedure and the corresponding radiation dose recorded if applicable.
Incidence of procedural complications
时间窗: up to 12 weeks
Occurrence of major complications during the procedure, including pericardial effusion, cardiac tamponade, stroke, or death.
