A 2100-g neonate underwent a two-ventricular surgical repair of a right ventricle-dominant unbalanced atrioventricular septal defect associated with the heterotaxy syndrome and sinus node dysfunction. Postoperative congestive heart failure persisted despite bradycardia management by temporary ventricular pacing. Spectral Doppler echocardiographic analysis of pulmonary venous inflow and aortic outflow patterns demonstrated significant improvement with transesophageal atrial pacing. Extended transesophageal pacing was performed for two days, resulting in dramatic clinical improvement. This is the first report of extended transesophageal atrial pacing complementing Doppler echocardiography predicting an improved outcome with permanent atrial pacing.
一名体重2100克的新生儿接受了右心室主导型不平衡房室间隔缺损合并内脏异位综合征和窦房结功能障碍的双心室手术修复。尽管通过临时心室起搏对心动过缓进行了处理，但术后仍持续存在充血性心力衰竭。对肺静脉血流和主动脉血流模式进行的频谱多普勒超声心动图分析显示，经食管心房起搏后有显著改善。进行了两天的延长经食管起搏，临床症状得到显著改善。这是关于延长经食管心房起搏辅助多普勒超声心动图预测永久心房起搏可改善预后的首例报告。
