Jpn Circ J. 1976 Jun;40(6):648-52. doi: 10.1253/jcj.40.648.

In congenital heart disease with pulmonary hypertension, the place for surgical correction still remains even with almost systemic PA pressure if R to L shunt ratio on lung scintigram is lower than 25%. 2) The patient with pulmonary hypertension in congenital heart disease younger than 3 years of age has wider acceptability for surgery compared to older patient. 3) In patients with mitral valvular disease, surgical correction seems to be indicated irrespective of PA pressure, if their preoperative U/L are lower than 2.4.

在患有肺动脉高压的先天性心脏病中，即使肺动脉压力几乎达到体循环水平，但如果肺闪烁造影显示右向左分流率低于25%，仍可进行手术矫正。2) 与年龄较大的患者相比，3岁以下患有先天性心脏病并伴有肺动脉高压的患者对手术的接受度更高。3) 在二尖瓣疾病患者中，如果术前尿素氮/肌酐比值低于2.4，无论肺动脉压力如何，似乎都应进行手术矫正。
