Congenital pulmonary venous return anomaly
MONDO:0017705Congenital pulmonary venous return anomaly is a cardiac malformation where some or all of the pulmonary veins drain into the right atrium or the systemic veins, with or without the presence of pulmonary venous obstruction, leading to various manifestations such as fatigue, exertional dyspnea, pulmonary arterial hypertension, cyanosis and progressive congestive heart failure. The two main subtypes are congenital partial pulmonary venous return anomaly (PAPVC), where one or a few of the pulmonary veins are anomalous, and congenital total pulmonary venous return anomaly (TAPVC), where all of the pulmonary veins are anomalous.
Also known as: congenital pulmonary venous connection anomaly, APVR, TAPVR, TAPVR1, anomalous pulmonary venous return, pulmonary venous return anomaly, scimitar anomaly, scimitar syndrome
