估计先心病室间隔缺损(VSD)患者缺损面积的大小,尤其是检出较小的缺损,对选择手术病例很有帮助。从心导管检查来计算缺损大小的公式,不仅需要右心且还需要左心导管的数据,因而使用相当受限。仅
Estimating the size of the defect area in patients with congenital ventricular septal defect (VSD), especially the detection of small defects, is very helpful in the selection of surgical cases. The formula for calculating the size of the defect from the heart catheterization not only requires the right heart but also the data of the left heart catheter, thus resulting in quite limited use. only
