“…Computerized tomography (CT) and magnetic resonance imaging are being used more recently in diagnosing and evaluating CHD. [2][3][4][5] In neonates with suspected CHD, CT may be used instead of catheterization to obtain detailed anatomic evaluation of the heart and great vessels if echocardiography is not conclusive. We report two cases where the diagnosis of TAPVR was not confirmed by echocardiography.…”

Total anomalous pulmonary venous return (TAPVR) is an uncommon cause of cyanotic congenital heart disease in the neonatal period. This diagnosis is often made by echocardiography. We present two cases where echocardiography was not confirmatory. Computerized tomography (CT) scan of the chest and abdomen with contrast was performed instead of cardiac catheterization to establish the diagnosis. We suggest that CT with contrast is a noninvasive modality to obtain anatomic details of pulmonary venous drainage in TAPVR when echocardiography is inconclusive.

“…15 Although conventional catheter angiography has been accepted as the gold standard-and it does enable detailed evaluation of the drainage of the PVs and of possible obstructions-it carries the risk of cardiac arrest and even of death in cases of obstructive TAPVC and severe cyanosis. 16 Magnetic resonance imaging offers several advantages over cardiovascular imaging: its true multiplanar capabilities, its lack of ionizing radiation, its absence of need for an iodinated contrast agent, and its ability not only to characterize shunt direction but also to quantify flow. [17][18][19] However, its disadvantages include lower spatial resolution, increased pixel size, susceptibility artifacts, and longer examination times.…”

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

“…Kim et al [9], studying 14 patients with TAPVC demonstrated that the combination of MDCT with three dimensional reconstruction helped in the diagnosis of TAPVC, being a good tool in the preoperative evaluation of neonates and infants [9]. However, it is not sufficiently adequate for visualization of intracardiac structures, due to heart rate and respiratory movements generally high.…”
