Abstract：Objective To observe the effect of pulmonary artery banding(PAB) on children with congenital heart disease complicated with pulmonary arterial hypertension (PAH);to investigate the effectiveness of pre-PAB use of cardiotonics and diuretics.Methods A total of 98 children with congenital heart disease and PAH who underwent PAB in Pediatric Cardiovascular Center,Beijing Anzhen Hospital,Capital Medical University from August 2010 to March 2016 were retrospectively analyzed.According to the type of malformation,the children were divided into functional single ventricle repair group (n =52) and delayed biventricular repair group(n =46).Systolic pulmonary artery pressure(sPAP) and oxygen saturation(SpO2) were recorded.The operative effect was analyzed.Results Thirteen children(10 cases in functional single ventricle repair group and 3 cases in delayed biventricular repair group) had cardiotonics and diuretics.In 98 children,postoperative sPAP and SpO2 significantly decreased compared to those before operation [functional single ventricle repair group:(28 ± 8)mmHg vs (59 ± 20) mmHg,(79 ± 6) ％ vs (90 ± 6) ％;delayed biventricular repair group:(27 ± 11) mmHg vs (53 ± 14)mmHg,(88 ±7)％ vs (97 ±4)％] (P ＜0.05).There were 3 cases(3.1％) of death;2 cases needed re-PAB to adjust the size of pulmonary artery band;2 cases had hydropericardium after operation.Nineteen children in functional single ventricle repair group had second stage surgery,including 1 case of total cavopulmonary connection,6 cases of right ventricular Glenn shunt,5 cases of right ventricular bidirectional Glenn shunt and 7 cases of bilateral bidirectional Glenn shunt.Ten children in delayed biventricular repair group had second stage surgery,including 5 cases of double outlet right ventricle surgery and 5 cases of total endocardial cushion defect surgery.Conclusions PAB can effectively restrict pulmonary blood flow.Combined use of targeted agents can consolidate the efficacy of PAB.
