MDCT of the left atrium and pulmonary veins in planning radiofrequency ablation for atrial fibrillation: a how-to guide. Cronin P, Sneider MB, Kazerooni EA et-al. total anomalous pulmonary venous return (TAPVR).Imaging differential considerations include: ![]() Therapeutic options include surgical repair with ASD patching, intracardiac baffle, anomalous vein anastomosis, systemic vein translocation and Warden procedure inter alia. It is considered the imaging modality of choice 3,4. Utilization of contrast-enhanced studies with MDCT technology enables both detection and characterization of the anomalies. Pulmonary venous congestion can be seen if the venous drainage is obstructed.Ĭardiomegaly can also be seen if significant abnormal intracardiac venous drainage occurs. The abnormal vein is rarely identified, except in cases of Scimitar syndrome. more rarely it is seen with ostium primum defect, a subtype of atrioventricular defectsĬhest radiographic features are particular to each subtype of PAPVR.in ~40% of patients with right-sided PAPVR, an atrial septal defect is seen 3.It is unclear if this is because of a higher proportion of symptomatic manifestation of the latter. The left upper lobe vein anomaly is thought to be most common. Left-sided PAPVR has been reported to be found more often in adults, whereas right-sided PAPVR is reported more commonly in children 3. a combination of two or more of the above anomalies.inferior vena cava ( Scimitar syndrome).brachiocephalic veins (=innominate veins).Cases of secondary pulmonary arterial hypertension have been reported 6,7. ![]() Patients with large shunts may present with symptoms of dyspnea, chest pain and palpitations, signs like tachycardia and murmur can be encountered. The overall prevalence of PAPVR is 0.4-0.7% 9. ![]()
