Ellis-Van-Creveld Syndrome and Congenital Cardiac Anomaly: Common Atrium with Atrioventricular Canal Septal Defect

Background: Children presenting with physical features of chondro-ectodermal dysplasia (Ellis-Van Creveld syndrome) such as skeletal and joint abnormalities often have concomitant congenital cardiac anomalies. Presence of cardiorespiratory symptoms in children with Ellis-Van Craved syndrome warrants a thorough cardiologic evaluation to recognize and treat underlying congenital heart anomaly. Aim: A child with physical stigmata of Ellis-Van-Creveld syndrome is evaluated to detect an associated congenital cardiac anomaly and accomplish successful repair of the underlying cardiac lesion to reduce the cardiac related morbidity and improve the patient survival. Case Presentation: Ten years old boy with chondroectodermal dysplasia (dental anomalies, genu valgum and other skeletal abnormalities) presented with dyspnea and cyanosis. Cardiac evaluation by 2D echo revealed an atrioventricular (AV) canal septal defect with AV valve regurgitation and a common atrium. Angiocardiography showed a goose neck deformity of the left ventricular outflow tract. The Qp/Qs was 3.4: 1, with systemic arterial oxygen desaturation (SaO2 of 0.7) and O2 saturation in the common atrium was 0.7. The pulmonary venous connections to the common atrium were anomalous. Atriotomy on cardiopulmonary bypass and on a cardioplegic arrest discerned a partial AV canal septal defect with a common bridging leaflet, clefts in septal leaflets of tricuspid and mitral vlalves, an incompletely closed interventricular communication, and a common atrium with highly anomalous pulmonary venous insertions well anterior (8 cm) to vena caval orifices. Intracardiac repair was performed with two patches of Goertex to partition the common atrium into the pulmonary and systemic venous chambers after repair of the partial AV canal septal defect. Patient required only a temporary afterload reduction with enalapril; otherwise patient had an uneventful postoperative course. At a 2-year follow-up, the child was well without AV valve regurgitation and had normal How to cite this paper: Sirivella, S.
