An infant with transposition of the great arteries was paced for postoperative heart block (single-site, right ventricular [RV] epicardial). She developed severe left ventricular (LV) dysfunction and septal dyskinesis. Resynchronization was performed at the age of 4 with an LV epicardial lead and an RV septal endocardial lead. The endocardial lead was affixed to the interventricular septum, then tunneled through the RV free wall and attached to an abdominal pulse generator. QRS duration decreased (176 to 122 ms) and LV ejection fraction improved (26 to 61%) and remained stable for 8 years. We present a case of successful resynchronization in congenital heart disease using a transmural RV septal lead.
一名患有大动脉转位的婴儿因术后心脏传导阻滞(单点,右心室 [RV] 心外膜)而接受起搏治疗。她出现严重的左心室(LV)功能障碍和室间隔运动障碍。在 4 岁时,使用 LV 心外膜导联和 RV 间隔心内膜导联进行了再同步化治疗。心内膜导联固定在室间隔上,然后通过 RV 游离壁隧道,并连接到腹部脉冲发生器。QRS 时限缩短(176 至 122ms),LV 射血分数改善(26 至 61%),并稳定 8 年。我们介绍了一例使用经室间隔 RV 心内膜导联成功治疗先天性心脏病的再同步化病例。
