Abstract：Objective To evaluate the diagnostic value of prenatal echocardiography in pulmonary atresia with intact ven‐tricular septum (PA/IVS) ,to analyze the reasons of misdiagnosed and to improve the echocardiographic diagnosis .Meth‐ods A retrospective echocardiographic review was performed on 19 fetus with PA/IVS confirmed by prenatal magnetic resonance imaging (MRI) or postnatal echocardiography .Results More common findings of PA/IVS were tricuspid valve regurgitation in 19 cases (100% ) ,reversed flow through ductus arteriosus by color Doppler flow imaging in 18 cases (94.7% ) ,and right ventricular hypoplasia in 13 cases(68 .4% ) .Among 19 PA/IVS fetus ,16 cases (84 .2% ) were diag‐nosed correctly by echocardiography .In the remaining 3 cases (15 .8% ) ,1 case with pulmonary valve stenosis ,tricuspid valve regurgitation and right ventricular hypoplasia and 1 case with mild tricuspid valve regurgitation were diagnosed by prenatal echocardiography ,1 case with intramyocardial sinusoids was misdiagnosed .Conclusion Combining visualization of PA/IVS in four‐chamber view ,outflow tract view ,and three vessels view ,PA/IVS could be accurately diagnosed by prenatal echocardiography ,but it should be differentiated from critical pulmonary valve stenosis .
