To determine the value of gated equilibrium angiography in secundum atrial septal defect (ASD) in children, the first pass pulmonic/systemic flow ratio (Qp/Qs) was compared with diastolic count ratio (DCR) and stroke count ratio (SCR) of the two ventricles. In 50 children we have found a correlation between Qp/Qs and DCR (r = 0.71) and between Qp/Qs and SCR (r = 0.66). For detection of significant atrial shunt (QP/Qs greater than 1.5) the sensitivity of DCR greater than 2 was 0.81 and the specificity 0.75. For SCR greater than 1.5 we sensitivity and specificity values of 0.87 and 0.71 respectively. Left and right ventricular ejection fractions were normal (0.67 +/- 0.08 and 0.50 +/- 0.07).
为确定门控平衡血管造影术在儿童继发孔型房间隔缺损（ASD）中的价值，将首次通过时肺循环/体循环血流比率（Qp/Qs）与两个心室的舒张期计数比率（DCR）及每搏计数比率（SCR）进行比较。在50名儿童中，我们发现Qp/Qs与DCR之间存在相关性（r = 0.71），Qp/Qs与SCR之间也存在相关性（r = 0.66）。对于检测明显的心房分流（QP/Qs大于1.5），DCR大于2时的敏感性为0.81，特异性为0.75。对于SCR大于1.5，敏感性和特异性值分别为0.87和0.71。左、右心室射血分数正常（分别为0.67±0.08和0.50±0.07）。
