A case of an infant, following surgical repair for double outlet right ventricle, who developed low cardiac output syndrome and complete heart block that required insertion of a pacemaker is presented. The infant underwent optimization of his ventricular function to determine whether pacing the right ventricle or left ventricle or both would improve cardiac function. Using standard two-dimensional echocardiography and Doppler imaging, tissue synchronization imaging, and two-dimensional speckle-tracking strain analysis, improvement in cardiac output and function was demonstrated. The present case highlights the usefulness of newer echocardiographic techniques in pacemaker optimization in the acute postoperative setting.
本文介绍了一例婴儿，在接受右心室双出口修复手术后出现低心输出量综合征和完全性心脏阻滞，需要植入起搏器。该婴儿接受了心室功能的优化治疗，以确定起搏右心室、左心室或两者都能改善心功能。使用标准的二维超声心动图和多普勒成像、组织同步成像和二维斑点追踪应变分析，显示心输出量和功能得到改善。本病例强调了在急性术后情况下，新的超声心动图技术在起搏器优化中的应用价值。
