[Partial anomalous pulmonary venous drainage: early diagnosis and complications after surgical repair of a rare pathology difficult to identify].

Partial anomalous pulmonary venous connection is a rare congenital heart defect and it is usually difficult to identify by transthoracic echocardiography alone. Here we report a case in a newborn, identified by echocardiographic imaging techniques with subcostal views, to detect the anomalous venous return. Our case is an uncommon one, as regards both its anatomy and early diagnosis. Surgical repair can be safely managed by means of multiple techniques with low morbidity. This correction may be associated with complications such as superior vena cava occlusion and sinus node dysfunction.
