Ebstein's disease with functional pulmonary atresia is a severe neonatal presentation of Ebstein's anomaly where the therapeutic management is typically based on the prescription of prostaglandins. The circular shunt is a serious "hemodynamic" complication which is often undiagnosed leading to the discontinuation of prostaglandins. We report a severe neonatal form of Ebstein's anomaly with hemodynamic deterioration relatted to a circular shunt. The diagnosis of Ebstein's anomaly with functional pulmonary atresia was made prenatally at 36 weeks of pregnancy. The patient was born at 38 weeks of gestation by caesarean section. Postnatal ultrasound confirmed the diagnosis. Treatment with prostaglandins was originally created to maintain the vital ductus arteriosus patent. Despite this treatment, hemodynamic deterioration was observed. Ultrasound monitoring showed pictures for a circular shunt. Indeed, blood coming into the pulmonary artery by the wide ductus arteriosus, was "drawn" to the right ventricle and the right atrium due to tricuspid regurgitation and from there to the left heart via the fossa ovalis shunting right to left, when it was ejected into the aorta and the ductus arteriosus. Before this circular shunt, treatment with prostaglandin was discontinued and treatment to reduce pulmonary resistance was described. However, the patient died prior to initiation of treatment. The neonatal form of Ebstein's anomaly is a severe form that can be complicated by a circular shunt. This hemodynamic phenomenon encourages early closure of the ductus arteriosus against indicating the prescription of prostaglandins.

Kawasaki disease (KD) is a common acute vasculitis in pediatric population that usually involves small and middle-sized arteries, commonly coronary arteries. Although the incidence and natural course of coronary aneurysms after KD are well documented, related reports on peripheral arterial and aortic aneurysms are scarce. We report an original case of a giant aortic aneurysm involving the horizontal part of aortic arch in a 28 months- old patient diagnosed with Kawasaki Disease. This complication was managed by steroids therapy in the beginning than surgery was indicated because of mechanical complication and risk of rupture.

Cantrell's pentalogy is a very rare syndrome associating varying degrees of midline wall defects and congenital cardiac anomalies. It is characterized by a combination of five anomalies that are: a midline supra umbilical abdominal wall defect, a sternal defect, an anterior diaphragmatic defect, a diaphragmatic pericardial defect and a congenital intra cardiac defect. Ectopia cordis, defined as a developmental defect in which the heart is abnormally located partially or totally outside the thorax, is in some cases a part of this syndrome. We report two cases of Cantrell's pentalogy in which cardiac ectopia was complete in one case and limited to left ventricular diverticulum in the other case. Both cases had a common intracardiac defect which is a double outlet right ventricle. The first case underwent surgical repair of the intracardiac lesions with resection of the diverticulum associated to repair of the midline defects with good outcome. The second case that presented with complete extra thoracic ectopia cordis died because of sepsis. We review through this article the main characteristics of Cantrell's pentalogy, we highlight the diversity of anatomic lesions and study the prognosis of this syndrome.
