[Case 1] A 32 year-old male had (I, D, D) type corrected transposition of the great arteries (cTGA) associated with ventricular septal defect and pulmonary stenosis. [Case 2] A 69 year-old male had (S, L, L) type cTGA associated with tricuspid regurgitation. Both cases showed advanced atrioventricular (AV) block due to HV block. Both patients had endocardial DDD pacemakers implanted, with no complication. (I, D, D) type cTGA is rarely accompanied with AV block, while the incidence of AV block is high in (S, L, L) type cTGA. We speculate that this results from the difference in the position of the AV node between these two types.
[病例1] 一名32岁男性患有（I，D，D）型矫正型大动脉转位（cTGA），合并室间隔缺损和肺动脉狭窄。[病例2] 一名69岁男性患有（S，L，L）型cTGA，合并三尖瓣反流。两例均因希氏束阻滞出现高度房室（AV）传导阻滞。两名患者均植入了心内膜DDD起搏器，无并发症。（I，D，D）型cTGA很少伴有AV传导阻滞，而（S，L，L）型cTGA中AV传导阻滞的发生率较高。我们推测这是由于这两种类型之间房室结位置的差异所致。
