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.
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.
We revealed the efficiency of the Glenn and Damus-Kaye-Stansel procedures using vector flow mapping.
超声心动图向量血流图可评估动态血流以治疗先天性心脏病。我们在格林分流术和达姆斯-凯-斯坦塞尔手术过程中使用向量血流图评估心内血流、能量损失、左心室输出动能和能量性能指标，以评估手术效果。
一名9个月大的男孩接受了格林分流术和达姆斯-凯-斯坦塞尔手术。能量损失取决于左心室前负荷；因此，格林分流术后能量损失减少。达姆斯-凯-斯坦塞尔手术后，由于体循环流出整合，动能会增加；然而，在我们的病例中，动能下降，这可能是因为动能也取决于左心室前负荷。在格林分流术和达姆斯-凯-斯坦塞尔手术后，我们检测到能量性能指标有所改善，表明心脏工作负荷也有所改善。
我们通过向量血流图揭示了格林分流术和达姆斯-凯-斯坦塞尔手术的效果。
