Background: In this study, we aimed to determine lobar distribution, drainage sites, and associated cardiovascular anomalies of partial anomalous pulmonary venous connection in pediatric patients using low-dose multidetector computed tomographic angiography. Methods: Sixty-one cases (27 female, mean age: 4.7 years) with partial anomalous pulmonary venous connection diagnosed by multidetector computed tomographic angiography were included in this study. In all patients, multidetector computed tomographic angiography examinations were performed using dual-source 256-slice scanner without sedation. Results: In 61 patients, 73 anomalous pulmonary veins were detected, 56 (77%) of them were right-sided and 17 (23%) were left-sided. Of 56 right-sided anomalous pulmonary veins in 49 patients, 38 (68%) drained into superior vena cava, eight (14%) into atriocaval junction, six (11%) into inferior vena cava, three (5%) into right atrium, and one (2%) into levoatriocardinal vein. Of 17 left-sided anomalous pulmonary veins in 12 patients, 16 (94%) drained into left innominate vein, and one (6%) into coronary sinus. Only seven (12%) patients had isolated partial anomalous pulmonary venous connection, whereas 54 (88%) patients had additional cardiovascular anomalies. The most common (66%) associated anomaly is atrial septal defect. The overall mean effective radiation dose was 1.12 mSv (range: 0.15-7.41 mSv), and it was 0.58 mSv (range: 0.15-0.73) in the patients younger than one-year old. Conclusions: The presence and course of the anomalous pulmonary veins and associated cardiovascular anomalies can be reliably detected by dual-source 256-slice multidetector computed tomographic angiography with low radiation doses.

We report the results of our retrospective evaluation, from February 2011 through August 2014, of the anatomic features of total anomalous pulmonary venous connection (TAPVC) and its associated cardiovascular anomalies in a pediatric population. In all 43 patients under study (23 female; average age, 9 mo [range, 4 d–7.1 yr]), these examinations had been performed with a dual-source 256-detector scanner. The type of TAPVC, the presence of obstruction, and the association with other cardiovascular anomalies were investigated and recorded. In accordance with the absence or presence of these accompanying anomalies, patients were subdivided into 2 groups: isolated and complex. In the 43 patients, 22 (51%) TAPVCs were supracardiac, 10 (23%) were cardiac, 6 (14%) were infracardiac, and 5 (12%) were mixed. Obstruction was detected in 7 patients. Seventeen patients were in the isolated group and 26 in the complex group. The diagnostic agreements between multidetector computed tomographic angiographic and surgical results were 100% in both the isolated and complex groups. The overall average effective radiation dose was 0.66 mSv (range, 0.15–1.11 mSv); and it was 0.52 mSv (range, 0.12–0.72 mSv) in patients younger than 1 year of age. We conclude that computed tomographic angiography with a dual-source 256-slice multidetector scanner is a reliable imaging method that enables, despite lower radiation doses, the detailed and comprehensive anatomic imaging of TAPVC in neonates and children.

Chester Disease

Erdheim-Chester disease is a rarely reported disease that can affect nearly every organ and chiefly infiltrates the connective, perivascular, and adipose tissue. The disease is a form of non-Langerhans-cell histiocytosis characterized by the proliferation of foamy histiocytes; its cardiovascular complications carry a severe prognosis. We present the case of a 29-year-old woman who was admitted for analysis of her angina. Our evaluation with use of cardiac multidetector computed tomographic angiography revealed large mediastinal soft tissue that compressed the patient's left anterior descending coronary artery. To our knowledge, this is the first report of the use of low-dose, dual-source, 256-slice multidetector computed tomography to characterize Erdheim-Chester disease that exclusively caused angina and stenosis of a coronary artery in a young adult.

Anomalous Pulmonary Venous Connection

Cor triatriatum may be associated with abnormalities of pulmonary venous anatomy. This case report describes a unique form of partial anomalous pulmonary venous connection. The patient presented at 5 weeks of age with symptoms of tachypnea and poor feeding. Echocardiography demonstrated cor triatriatum and partial anomalous pulmonary venous drainage of the right upper lung. The patient underwent urgent repair of cor triatriatum. It was elected to not address the partial anomalous pulmonary venous connection at that time. The patient returned at age 19 months for elective repair of the anomalous pulmonary venous connection. There was also a large vein connecting the right lower pulmonary veins to the superior vena cava. This was repaired by dividing the superior vena cava along a vertical axis to redirect the flow of the anomalous pulmonary veins through the connecting vein to the left atrium. This report describes the anatomy and surgical approach to a unique form of anomalous pulmonary venous connection.

Tomographic Angiography

Congenital pulmonary venous anomalies are not uncommon that can occur either in isolation or in association with different forms of congenital heart disease. Clinical presentation of these anomalies may vary from the relatively benign single anomalous partial pulmonary venous return to life-threatening critical obstructed total anomalous pulmonary venous return. Accurate delineation of these anomalies and accompanied cardiovascular anomalies are crucial to guide decision making in these patients. Low-dose high-pitch dual-source 256-detector multidetector computed tomographic angiography is a fast and reliable imaging modality allowing comprehensive noninvasive anatomic imaging in neonates and children with congenital pulmonary venous anomalies with lower radiation doses and should be preferred for these patients after transthoracic echocardiography.
