背景：超声心动图向量血流标测技术可以评价动态血流，用于先天性心脏病的治疗。我们在Glenn和Damus-Kaye-Stansel手术期间使用矢量流标测评价心内流量、能量损失、左心室输出动能和能量性能指数，以评估手术的有效性。一个9个月大的男孩接受了Glenn和Damus-Kaye-Stansel手术。能量损失取决于左心室前负荷;因此，Glenn手术后能量损失减少。在Damus-Kaye-Stansel手术后，由于整合的全身流出，动能将增加;然而，在我们的病例中，动能减少，这可能是因为动能也取决于左心室前负荷。在Glenn和Damus-Kaye-Stansel手术后，我们发现能量性能指数有所改善，表明心脏工作负荷也有所改善。结论我们使用向量流标测显示了Glenn和Damus-Kaye-Stansel手术的有效性。
Background: Echocardiography vector flow mapping can assess dynamic flow to treat congenital heart diseases. We evaluated intracardiac flow, energy loss, left ventricular output kinetic energy, and energetic performance index using vector flow mapping during Glenn and Damus-Kaye-Stansel procedures in order to assess the efficacy of the surgery. Case presentation A 9-month-old boy underwent Glenn and Damus-Kaye-Stansel procedures. The energy loss depends on the left ventricular preload; therefore, energy loss decreased after the Glenn procedure. After the Damus-Kaye-Stansel procedure, the kinetic energy would increase owing to the integrated systemic outflow; however, in our case, kinetic energy decreased, which was potentially explained by the fact that kinetic energy also depends on the left ventricular preload. After the Glenn and Damus-Kaye-Stansel procedures, we detected an improvement in energetic performance index, indicating that the cardiac workload improved as well. Conclusion We revealed the efficiency of the Glenn and Damus-Kaye-Stansel procedures using vector flow mapping.
