Catheter ablation (CA) of atrial tachyarrhythmias (ATs) in patients with complex congenital heart disease (CHD) often requires technically challenging transbaffle or transconduit puncture. The aim was to assess the feasibility and safety of transbaffle/transconduit puncture based on computed tomography (CT) three‐dimensional (3D) reconstruction merged with electro‐anatomical mapping (EAM) without per‐procedure echocardiographic guidance.

先天性心脏病患者使用简单的CARTO引导方法进行超声/穿刺穿刺，无需超声心动图检查。

患有复杂先天性心脏病（CHD）的患者的房室快速性心律失常（AT）的导管消融（CA）通常需要在技术上具有挑战性的经导流或经导管穿刺。目的是在无手术超声心动图指导的情况下，基于计算机断层扫描（CT）三维（3D）重建与电解剖标测（EAM）结合，评估经导流管/跨导管穿刺的可行性和安全性。
