“…Furthermore, when the anomalous connection is to the portal venous system, the high resistance of the hepatic parenchymal circulation creates its own barrier to blood flow for the PV. 20 Children with infracardiac TAPVC accounted for 42% of the obstructed veins in our study. In one child, obstruction was at the left hepatic vein-to-inferior vena cava connection; in another child, at the vertical veinto-ductus venosus connection; and in a third child, at the diaphragmatic level.…”

“…Although obstruction can occur in any type of TAPVC, it is most often encountered in the infracardiac type, 20 wherein the PVs drain a confluence posterior to the left atrium. A descending vertical vein originates from this confluence, passes through the esophageal hiatus, and drains below the diaphragm into the portal venous system, the inferior vena cava, the hepatic veins, the ductus venosus, or the azygos vein.…”

“…Obstruction is unusual in this type of TAPVC. 20 Because radiation exposure with MDCTA has become a foremost concern-especially in children, consequential to the risks of radiation-induced chromosomal DNA damage and cancer-every approach to the minimization of radiation dosage (while preserving image quality) is important. One should always apply the principle of "as low as reasonably achievable."…”

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 T otal anomalous pulmonary venous connection (TAPVC) constitutes approximately 1% to 3% of all cardiovascular abnormalities in which the pulmonary veins (PVs) have no connection with the left atrium and connect directly to the right atrium or to one or more systemic veins. 1 Embryologically, TAPVC results from early atresia or failure of the common PV to develop, with persistence of at least one connection to the cardinal or the umbilical vitelline venous system. 2 Total anomalous pulmonary venous connection is a cause of neonatal cyanosis and can result in rapid death when blood is not shunted from the right side of the heart to the left side. Isolated TAPVC is diagnosed if the patient has atrial septal defect (ASD), patent ductus arteriosus (PDA), or both; complex TAPVC is diagnosed if the patient has other intracardiac lesions in addition to ASD or PDA. Although TAPVC is usually isolated, it can be a component of a complex cardiovascular disease such as heterotaxy syndrome. 3 Accurate delineation of TAPVC and the cardiovascular anomalies that accompany it are important to the guidance of surgical planning in these patients.Although TAPVCs have usually been evaluated with use of echocardiography and catheter angiography, magnetic resonance imaging (MRI) and multidetector computed tomographic angiography (MDCTA) are now playing larger roles in the diagnosis of these anomalies. 4 These imaging methods help overcome the shortcomings of transthoracic echocardiography (TTE), which gives a suboptimal acoustic window and a poor depiction of extracardiac vascular structures. They are also an improvement over catheter angiography, which produces overlapping views of adjacent vascular structures, causes difficulty in the simultaneous depiction of the systemic and pulmonary vascular systems, leads to undesirable catheter-related sequelae, and delivers relatively high doses of ionizing radiation. 5 Even though MRI is eminently

Total anomalous pulmonary venous return (TAPVR), also known as total anomalous pulmonary venous connection, is a congenital cardiovascular malformation that presents itself in the neonatal period, with cyanosis and tachypnea. There are 4 types of TAPVR with the mixed type being the least common. Any type of TAPVR may be associated with obstruction as result of flow redirection through the liver parenchyma before it may return to the heart, but infracardiac is the most common one.We report a case of a 10-hour-old female, with a mixed (cardiac and infracardiac) TAVPR with obstruction, that showed drainage to the coronary sinus and the portal vein, as the other classic findings in TAVPR, made with computed tomography angiography and echocardiogram. The patient was taken to surgical repair, but unfortunately died during the procedure because of multiple complications.

“…Chest radiography (CXR), electrocardiography and transthoracic echocardiography are non-invasive methods typically used to screen children with a suspected TAPVC. More recently, computer tomography (CT)-assisted angiography has also become a reliable tool in the preoperative evaluation of cardiac anatomy in TAPVC patients [8]. Despite technological advancements, diagnosis of TAPVC is especially challenging in neonates and infants with developing mediastinal structures, as it is highly dependent on the clarity and resolution of the images obtained.…”
