室间隔缺损(VSD)是先天性心脏病中的常见病,但有关VSD自然愈合过程中肺血及心影征象的改变罕有报道,而且临床上一直习惯从X线胸片中肺血及心影的情况来估计VSD的大小并决定是否需手术治疗,但实际上,有时用此种方法往往估计有错误。自超声心动图尤其是二维多普勒超声应用于临床以来,以其无创准确,对VSD的诊断符合率极高,对VSD的愈合亦提供可靠的证据,现根据我们 Ventricular septal defect (VSD) is a common disease in congenital heart disease. However, the changes of lung blood and heart shadow in the course of natural healing of VSD have rarely been reported, and have been clinically used to detect pulmonary blood and heart shadow Of the situation to estimate the size of the VSD and decide whether the need for surgical treatment, but in fact, this method is often used to estimate the error. Since echocardiography, especially two-dimensional Doppler ultrasound in clinical applications, with its non-invasive and accurate diagnosis of VSD with a very high rate of VSD healing also provide reliable evidence is based on our
