Journal of Cardiothoracic Surgery 2011 6 126 http www.cardiothoracicsurgery.Org content 6 1 126 JCTS JOURNAL OF CARDIOTHORACIC SURGERY CASE REPORT Open Access Partial anomalous pulmonary venous return and atrial septal defect in adult patients detected with 128-slice multidetector computed tomography Sari Kivisto1 Helena Hanninen2 and Miia Holmstrom3 Abstract The present series describes a group of adults with left-to-right shunts including partial anomalous pulmonary venous return PAPVR and or an atrial septal defect ASD evaluated with ECG-gated 128-slice multidetector computed tomography MDCT . PAPVR is defined as a left-to-right shunt where one or more but not all pulmonary veins drain into a systemic vein or the right atrium. PAPVR involving the right upper pulmonary vein can be associated with a sinus venosus ASD. The presence course number of anomalous veins and associated cardiovascular defects can be reliably observed by 128-slice MDCT angiography. Keywords Partial anomalous pulmonary venous return PAPVR Atrial septal defect ASD Multidetector computed tomography MDCT Background Partial anomalous pulmonary venous return PAPVR is defined as a left-to-right shunt where one or more but not all pulmonary veins drain into a systemic vein or the right atrium. Anomalous right-sided pulmonary veins can drain into the superior vena cava SVC right atrium inferior vena cava azygos vein hepatic vein or portal vein. The connecting sites for anomalous left-sided pulmonary veins can be the left brachiocephalic vein coronary sinus and hemiazygos vein. PAPVR involving the right upper pulmonary vein can be associated with a sinus venosus atrial septal defect ASD located near the SVC orifice 1 . All PAPVRs are left-to-right shunts but unless more than 50 of the pulmonary flow drains to the right side of the heart clinical manifestations are rare.
