摘　　要：Background:Communication between the right pulmonary artery(RPA)and left atrium(LA)is a rare cause of central cyanosis in pediatric patients.Case presentation:We describe a 3-year-old female patient with an oxygen saturation of 70%at admission.The echocardiogram indicated an abnormal color flow Doppler in the LA and she underwent standard cardiac catheterization.The angiography of pulmonary artery revealed a 7.4 mm×7.6 mm fistula between the RPA and LA and achieved successful closure using ventricular septal defect occlusion.Conclusion:The fistula between pulmonary artery and left atrium is an extremely rare but treatable congenital defect.It should be considered in differential diagnosis of cyanosis in children.
