Absent right atrioventricular connexion with the left atrium connected to the morphologically right ventricle, a right-sided rudimentary left ventricle, and right juxtaposition of the atrial appendages: documentation by angiography and cross-sectional echocardiography

In this report, a 12-hr-old male infant was demonstrated to have the absent connexion variant of right atrioventricular valve atresia with the left atrium connected to the morphologically right ventricle with a right-sided rudimentary left ventricle. The aorta arose from the right ventricle and there was pulmonary atresia, the pulmonary circulation being duct-dependent. In addition there was right juxtaposition of the atrial appendages. The definitive cross-sectional echocardiographic and angiographic findings are presented.
