Neonatal Ebstein's anomaly with type B Wolff-Parkinson-White syndrome: a case report / 中华围产医学杂志

ABSTRACT

This paper reported a male newborn with Ebstein's anomaly complicated by type B Wolff-Parkinson-White syndrome. The baby was delivered at 39 weeks of gestation and diagnosed as Ebstein's anomaly complicated by type B Wolff-Parkinson-White syndrome 2 d after birth. He was improved and discharged after conservative management in the Department of Internal Medicine. No abnormality was found by fetal echocardiography at 20 weeks of gestation, while supraventricular tachycardia was diagnosed by M-mode ultrasonography at 38 weeks of gestation due to rapid fetal heart rate. In addition to hemodynamic changes,the abnormal cardiac structure in patients with Ebstein's anomaly may also lead to tachyarrhythmia. Therefore, in fetuses diagnosed with supraventricular tachycardia by prenatal ultrasound or children with type B Wolff-Parkinson-White syndrome detected by electrocardiogram after birth, tricuspid valve should be carefully scanned under echocardiography to avoid the missed diagnosis of Ebstein's anomaly.
